Why can the equation for the reaction of Na with H2SO4 be written as a Na

The reaction between Na and H2SO4 is theoretically preceded by the reaction of water, and then the generated NaOH reacts with H2SO4, and what he said can be about off means that water can be about off (the first step consumes 2mol of water, and the second step of the second part generates 2mol of water, so it is flat, and the water is equivalent to not participating in the reaction).

But the reaction between Na and H2SO4 must be 2molNa corresponding to 1molH2SO4, because you see they finally react into Na2SO4, a Na2SO4 molecule has two Na ions and one SO4 ion, the elements are conserved, and one Na provides a Na ion, so there must be 2 Na, and one H2SO4 provides an SO4 ion, so only one H2SO4 is needed, so it should be your chemistry teacher's mistake.

The reaction between NA and H2SO4 is essentially NA replacing H in H2SO4, if you still don't understand, you can see that 2Na+2H2O=2NaOH+H2OH2 2NaOH+H2SO4=Na2SO4+2H2O H2O H2O and NaOH are unchanged, in the first reaction formula consumes water, and in the second reaction formula the same amount of water is generated, and the same is true for NaOH, they are neither generated nor consumed. The two equations can be added together, and H2O and NaOH can be reduced, which is 2Na+H2SO4=Na2SO4+H2

2na+2h2o=2naoh+h2 ①

2naoh+h2so4=na2so4+2h2o---2naoh=na2so4+2h2o - h2so4

Substitute naoh

2na+2h2o=na2so4+2h2o - h2so4+h2 shift2na+2h2o+h2so4=na2so4+2h2o +h2 remove the same water on both sides 2na+h2so4=na2so4 +h2 is the total reaction equation, if balanced, there should be two na...

For the two reactions, we let them add left and left respectively, and right plus right, then 2Na+2H2O+2NaOH+H2SO4=2NaOH+H2+Na2SO4+2H2O, and reduce the NaOH and H2O on the left and right, then we finally get the formula 2Na+H2SO4=H2+Na2SO4.

Na and H2O reactionsChemical equationsYes: 2Na+2H2O=2NaOH+H2.

Analysis: The reaction between sodium and water is explosion, luminescence and heating, and the sodium-water reaction refers to the fact that when sodium and water or steam are in contact, they will slowly heat up, resulting in the phenomenon of explosion and luminescence, which is a strong chemical reaction.

Phenomena of Na and H2O reactions:1. Sodium metal.

When placed in water, sodium floats on the surface of the water.

2. Sodium swims rapidly on the surface of the water and has a slight hissing sound.

3. The sodium melts into a bright ball.

4. After the reaction, phenolphthalein is dropped into the solution.

The solution turns red. 5. The generated gas can be ignited and has a banging sound.

2na2o2+2h2o===4naoh+o2

At the same time, there is also a reaction: Xiangxianghe na2o2+h2o===2naoh+h2o2

Can react. nahso4+nahso3==na2so4+h2o+so2↑

Because NaHSO4 is completely ionized, the sulfite ions produced by the ionization of celery late hydrogen ions and NaHSO3 are counter-suspicious to generate sulfurous acid, which decomposes to water and sulfur dioxide.
