Why is a chemical reaction also called a chemical equation ? I don t feel like an equation!

The chemical equation refers to the fact that a chemical reaction follows the conservation of mass.

Conservation of mass: In a chemical reaction, the sum of the masses of the substances before participating in the reaction is equal to the sum of the masses of the substances generated after the reaction. This is called the law of conservation of mass.

The process of chemical reaction is the process of recombining the atoms of each substance (reactant) participating in the reaction to form other substances. In a chemical reaction, the type of atoms does not change before and after the reaction, the number does not increase or decrease, and the mass of the atoms does not change.

The chemical reaction formula and the equation, the left and right sides are "consistent" is similar to the equation, and the "agreement" here is the connotation is the same, the difference is only the way of expression.

The equation is an equation containing unknowns, that is, the algebra and equality of both sides and the unknown number is introduced, while the chemical reaction equation can be deduced without knowing the products and reactants, and it follows the law of conservation of mass, which itself is conserved, and conservation is the equation, so it is a chemical reaction equation.

equation: The meaning of an equation.

Chemical Equation: A chemical equation.

An equation is an equation that expresses the equality relationship between two mathematical formulas (e.g., two numbers, functions, quantities, operations), usually with an equal sign "=" between them. Equations don't have to think backwards, they can be directly listed and contain unknowns.

It comes in many forms, such as unary linear equations, binary linear equations, etc. It is widely used in mathematics, physics and other science applications.

The chemical equation, on both sides of it, is conserved in energy and in matter. It's an abstract relation, so it's called an equation, or an equation, but no one calls it that, and it's all translated from English.

The full name of chemical reaction formula is chemical reaction equation, referred to as chemical equation.

Because the definition of an equation is an equation that expresses the equality relationship between two mathematical formulas such as two numbers, functions, quantities, operations, etc.

The chemical equation must obey the law of conservation of mass, which means that the types and numbers of atoms on both sides of the equal sign must be equal.

Therefore, since the chemical reaction formula represents an equality relation, it can be called an equation.

If it is separated from the examination-oriented education of junior and senior high schools, it is actually the same name, and there is no substantive difference.

In organic reactions, the products are not fixed, and there are many side reactions that accompany the main reaction. So you can only write out the products that may be generated, and you can't trim. Here the reaction formula and the equation are basically equivalent.

Most inorganic reactions can be trimmed, and the product is fixed under certain conditions.

Equations with unknowns in mathematical concepts are equations. In chemistry, the left side is the known reaction, and the right side is the unknown reaction, and "*****" is abstracted as an equal sign in mathematics, in order to make the left and right sides equal.

It's purely a personal opinion.,,Don't throw it if it's not good.。。

A chemical equation, also known as a chemical reaction equation, is a formula that uses a chemical formula to express the chemical reaction between different substances. You can find the mass ratio according to the chemical equation and use it to solve the problem or something.

This hasn't been studied. It may be that the left and right sides are equal under certain conditions, or the reactant products can be inferred by the formula.

The chemical reaction rate equation is an equation that calculates the reaction rate of a chemical reaction using the concentration or partial pressure of the reactants.

The rate of a chemical reaction usually refers to a decrease in the concentration of reactants or an increase in the concentration of products per unit of time. Depending on the length of time, the unit time can be expressed in different units such as s, min, hr, day, year, etc., which depends on the speed of the reaction.

The chemical reaction rate equation directly calculates the instantaneous rate at a specific concentration, and the average rate is derived from the integration of both sides of the equation.

Matches that are about to extinguish embers in the air will rekindle when placed in pure oxygen.

It shows that the system with a large concentration has more activated molecular groups than the system with a small concentration, the number of effective collisions increases, the reaction is accelerated, and as a result, the ember matches are rekindled.

In primitive reactions, or in the primitive steps of non-primitive reactions, there is a strict quantitative relationship between the reaction rate and the concentration of reactants, i.e., the law of mass action is followed.

At constant temperature, the rate of the radical reaction is proportional to the continuous product of the power of the reactant concentration, and the power exponent is equal to the stoichiometric number in the reaction equation, which is the law of mass action, and the above equation is also called the expression of the law of velocity.

Definition of the reaction rate equation.

The expression of the law of mass action is often referred to as the reaction rate equation [2], where [a] denotes the concentration of reactants at a certain moment and vi is the instantaneous rate of reaction expressed by the concentration of species i, i.e., the instantaneous rate when the reactant is [a].

ki is a rate constant that does not vary with concentration during the reaction, but ki is a function of temperature, and at different temperatures, ki is different.

The sum of a and b, which is called the reaction order of this primitive reaction, can be said to be a (a+b) order reaction. It can also be said that the reaction is grade A for A and B for B.

In a primitive reaction, a molecule and a molecule b are collided to complete the reaction, and we say that the number of molecules in this reaction is (a+b), or this reaction is a trillion deficit (a+b) molecular reaction.

Only the number of reactive molecules can be said to be the number of reactive molecules, in the primitive reaction, the number of reactive molecules and the number of reactive molecules are equal, but the number of reactive molecules is a microscopic quantity, and the reactive order is a macroscopic quantity.

This reaction is the Hoffman degradation reaction:

Hoffmann degradation reaction (also known as Hoffman rearrangement) refers to the reaction of amide with sodium hypochlorite or sodium hypobromide alkali solution to remove carbonyl group to produce one less carbon primary amine: R-CONH2 + NaOX + 2NaOH - R-NH2 + Na2CO3 + Nax + H2O

The reaction mechanism is shown in Fig

1. Bromine atom replaces 1 h atom.

2. Hydrogen bromide is added to the double bond, and H is added to C by the benzene ring.

3. Oxidation to terephthalic acid.

4. OH substitution of chlorine atom position.

K2CO3 + 2HCl = 2KCl + CO2 + H2O, which emits a large amount of gas.

CO2 + Ca (quietly withered OH) 2 = CaCO3 + H2O, resulting in a spike hand white precipitate.

CO+CUO=Heating=CO2+CU, the black solid gradually turns red.

3CO+FE2O3=High temperature=2FE+3CO2, the red solid suspect gradually turns black, and the Fe particles are black.

CH4 + 2O2 = ignition = CO2 + 2H2O

It glows and heats, and the flame is pale blue.

2C2H2 + 5O2 = Ignition = 4CO2 + 2H2O Luminescence and Heat, with black smoke (the mass fraction of C in C2H2 is too large, C can not be completely reacted, and C particles will be generated).

4Fes2 + 11O2 = 2Fe2O3 + 8SO2 The object gradually changes from black to reddish-brown.

Yes, your steps:

Write the equation and write the soluble ions separately (e.g. Ba(OH)2 split into Ba2+ and 2OH - if there are the same ions on the left and right sides, they should be canceled out at the same time.

Probably you have an oh- on the left and right sides of your equation, and the cancellation has ba2+ and an oh- on the left.

Finally, the test: the left and right elements are conserved and the charge is conserved. At this time, the left and right charges may not be 0, (for example, yours, with oh- elimination, generally not 0), but the number of left and right charges must be equal.

However, or because barium hydroxide is excessive, we break down the deficiency according to its composition and distribute the excess according to demand. Ba(OH)2 is an ionic compound, which is barium ion and hydroxide ion in water, and it needs to be extracted as much as it wants.

Find a few ion reactions and test them yourself.

What you said about BA(OH)2 should be split into 1 to 2 in the reaction, and the answer may be questionable.

Isn't it written as a simple reaction equation without trimming.

It's just to write just reactant + reactant — product + product kind.

In order to prevent omissions in the calculation of the number of times, Ba(OH)2 is artificially prescribed, and it is written as Ba2+ 2OH- in ionic reactions, and the number ratio is 1:2, for example.

The ion equation for Ba(OH)2+NaHCO3=BAC3 +NaOH+H2O is.

ba2+ +2oh- +na+ +hco3- =baco3 + oh- +na+ +h2o

Generally speaking, that's pretty much it for writing here.

However, the ionic equation generally simplifies the solubles, that is, the same ionic clusters are subtracted from the left and right sides, and the formation will be formed.

BA2+ +OH- +HCO3- =BAC3 + H2O, this may be the 1:1 relationship that LZ is talking about.
