Science help me please :))

There will be 2 nitrogen and 2 oxygen atoms in the product.

Explanation:

In a chemical reaction, atoms are neither created or destroyed, which means if there are 2 nitrogen atoms in the reactants, there will be 2 nitrogen atoms in the products. Similarly, if there are 2 oxygen atoms in the reactants, there will be 2 oxygen atoms in the products.

Let me know if this helps!

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
