You form water vapor by mixing oxygen and hydrogen at 730°C in a 5.4-liter container. This is the equation for the reaction:

O2(g) + 2H2(g) → 2H2O(g).

The partial pressure of oxygen before the reaction is 122.3 kilopascals, and there is excess hydrogen. How many moles of water are formed?

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

m=9

step-by-step explanation:

catya that's not even a b or c

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
