Jason combines the two intermediate steps shown. na(g)+o2(g) -> 2no(g) 2no(g)+o2(g) 2no2(g) which best describes what jason should do with the oxygen molecules? place two of them as products. place two of them as reactants. cancel them out because there is one in each equation. double them because there is one in each equation.

Place two of them as reactants.

Explanation:

1) N₂(g ) + O₂(g) → 2NO(g).

2) 2NO(g )+ O₂(g) → 2NO₂(g).

N₂(g ) + 2O₂(g) → 2NO₂(g).

NO is cancelled out because there is one in each equation in the products side in eq. 1 and in oriduct side in eq. 2.

So, we place two of oxygen as reactants.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
