With all the coefficients set to 1, how can you tell that the equation is not balanced?
Select all the correct answers.
1)The number of hydrogen atoms in the reactants does not equal the number in the products,
2)The number of nitrogen atoms in the reactants does not equal the number in the products.
3)The number of ammonia molecules in the products does not equal the number in the reactants.
4)There are two molecules in the reactants, but there is only one molecule in the products,

#1 and #2 are the correct answers.

Explanation: The equation isn’t balanced because the amount of hydrogen and nitrogen in the reactants doesn’t match the amount of hydrogen and nitrogen in the products. When the coefficients are all set to 1, there are two nitrogen atoms in the reactants but only one in the products. Similarly, there are two hydrogen atoms in the reactants, but three in the products.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
