Sodium hydrogen carbonate reacts with sulfuric acid to produce sodium sulfate, water, and carbon dioxide.

Write the equation out, balance, and tell what kind of reaction it is:

2NaHCO3(aq)+H2SO4(aq)→Na2SO4(aq)+2CO2(g)+2H2O(l)

Explanation:

As we know that

acid + carbonate  →  salt + carbon dioxide + water

So, the general (un-balanced) equation would be-

NaHCO3(aq)+H2SO4(aq)→Na2SO4(aq)+CO2(g)+H2O(l)

Now we will write the net ionic reactions

----> CO2(g)↑+2H2O(l)

Adding all the above equation, we get

2NaHCO3(aq)+H2SO4(aq)→Na2SO4(aq)+2CO2(g)+2H2O(l)

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
