Can anyone give me all the chemistry formulas for my first year of high school?

Just spend 5 bucks and buy a math formula book with an explanation.

C = NV = 1000 WM

You write "what", is ww refers to the mass fraction of the solute in the solution, and the following: it is written as:

The prerequisite for 1000 W m = 1000 [s (100+s)] m is that the solution is saturated and s indicates the solubility of the solute. For saturated solutions, there are: w = s (100 + s).

If the dissolution is not saturated, c = n v 1000 W m holds, but:

1000 W m = 1000 [s (100+s)] m does not hold.

Let the solution be 1 L

CB = NB V solution = 1000 WM

w is the mass fraction of the solution.

m is the letter of the quantity of matter! It should be the mass that is calculated!

1.The formula is c=1000pw m.

It can be derived as follows: w = m (solute) m (solution) = PV m (solution). And the amount of matter n=m m, because c=n v

This is also because the concentration of the quantity is measured in moles per liter, whereas in the density formula, the volume of the gas is measured in liters. Therefore, the conversion of the two is 1000.

So c=n v=m mv=wm mv=wpv mv=1000pw m.

2.The principle of conservation of charge is: in a chemical reaction, the number of electrons carried by a substance is conserved.

In the redox reaction, if the valence increases, there must be a decrease, and the increased valence is equal to the decreasing valence. The valency change is reflected in the gain and loss of electrons, the number of electrons is equal to the number of charges, so the number of gains and losses is the same, that is, the charge is conserved. A strong electrolyte is a substance that can be completely ionized, and before ionization, the substance is electrically neutral, that is, the number of positive and negative charges carried by anions and cations is equal.

After ionization, no new matter will appear, and the conservation of matter will be satisfied from a macroscopic point of view. Therefore, in a strong electrolyte solution, the anions and cations satisfy the principle of conservation of charge.

Formula c = 1000 PWM (the mass fraction of the solution is w, and the concentration of the substance is c

The density of the solution is p

m is the molar mass of solute) can be understood: c = the amount of solute species in the solution The volume of the solution, 1L of solution is taken in the formula, and 1000pw m is equivalent to the amount of solute in 1L of solution.

The principle of conservation of charge refers to the equality of the total number of anionic and cation charges in the electrolyte solution, that is, the sensible neutrality of the solution, such as in HAC (acetic acid) solution: C(CH3COO-)+C(OH-)=C(H+). And so on NaCO3 solution:

c（na+）+ch+）=c（co3

The conservation of 2-)+C(HCO3-)+C(OH-) charge can be understood as follows: water molecules are ionized, and for every H+ ionized, an OH- must be ionized, and the same is true for the ionization of solute branches.

Dude, is that clear?

c=1000p*w m (m is the molar mass of the solute) derivation process: the amount of solute substance--n, the volume of the solution --v, the density of the solution-- the mass fraction of the solution--w, the molar mass of the solute m, the solute mass m= vw=nm, obtained.

n = vw m, and the amount concentration of the solute is c = n v = vw m v = w m, but in chemistry, the unit of volume is generally l (liter), and the unit of density is g cm3, then the unit of c = w m introduced above is mol cm3, and the conversion of the leased silver pin is 1000mol l, (because 1l = 1000cm3), so it is dug out:

c=1000*w m, is the formula for the standard unit mol l.
