How many moles of water are produced when 6.0 moles of hydrogen gas react with 2.5 moles of oxygen gas? Balanced equation: 2H2 + O2 → 2H2O

Answers:
6.0 moles of water
3.0 moles of water
5.0 moles of water
2.5 moles of water

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

i think it is true since you can test the answer and can use observations to complete it.

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
