PL HEL BRAINLIEST FOR WHO GETS IT RIGH Which of the following statements are true about the following chemical equation? 4Na + O2 > 2Na2O
Question 4 options:

1 molecule of sodium combines with 1 molecule of oxygen to make 2 molecules of sodium oxide

4 molecules of sodium combine with 2 molecules of oxygen to make 2 molecules of sodium oxide

4 molecules of sodium combine with 1 molecule of oxygen to make 1 molecule of sodium oxide

4 molecules of sodium combine with 1 molecule of oxygen to make 2 molecule of sodium oxide

n+h→nh3

we must remember that nitrogen and hydrogen are both diatomic molecules in their standard gas form. this adjusts the equation to

n2+h2→nh3

now we need to adjust coefficients in order to balance the atoms on each side of the equation. currently we have 2 atoms of nitrogen and 2 atoms of hydrogen on the reactant side and 1 atom of nitrogen and 3 atoms of hydrogen on the product side.

we can balance the hydrogens by placing a coefficient of 2 in front of ammonia and a coefficient of 3 in front of the hydrogen.

n2+3h2→2nh3

this gives us 6 hydrogen on each side and coincidentally the nitrogens now equal 2 on each side.

let that person have a turn to speak : )

it is the most commonly accepted one

the answer is d. 74.02
