Question

What are the coefficients in the balanced equation below? 1 H2SO4 + 2 NaNO2 ---> 2 HNO2 + 1 Na2SO4

a. 10:10
b. 6:4:4:6
c. 2:4:2:2:2:4
d. 1:2:2:1

Answer 1

The correct coefficients for the balanced chemical equation 1 H2SO4 + 2 NaNO2 → 2 HNO2 + 1 Na2SO4 are 1:2:2:1.

Step-by-step explanation:

The coefficients in the balanced equation 1 H2SO4 + 2 NaNO2 → 2 HNO2 + 1 Na2SO4 indicate the number of moles of each substance that react or are formed. Looking at the equation, it is clear that the coefficients are 1, 2, 2, and 1, respectively.

Thus, the correct answer to which set of coefficients balances the equation is d. 1:2:2:1.
