How many moles of C2H2 are needed to react completely with 84 mol O2

Chemistry
1 answer:
Butoxors [25]3 years ago
4 0

Balanced chemical equation:

2 C2H2 + 5 O2 = 4 CO2 + 2 H2O

2 moles C2H2 ---------------- 5 moles O2
moles C2H2 ------------------ 84 moles O2

moles C2H2 = 84 * 2 / 5

molesC2H2 = 168 / 5 => 33.6 moles of C2H2

The p subshell can hold up to eight electrons in an atom (2 points)<br> True or false?
hoa [83]

Answer: The statement is false

Explanation:

Electrons occupy a region in atoms known as orbitals or subs hell.  These orbitals include

I) S-orbital: it can occupy a maximum of two electrons

II) P-orbital: It occupies a maximum of six electrons

III) D-orbital: it occupies a maximum of ten electrons

F and G-orbitals as examples of other orbitals present.

A good illustration of the 6 electrons occupied by the P-subshell is seen in Sodium (Na) with atomic number of 11

Na = 1s2, 2S2 2p6, 3s1

Note: extra electrons are transferred to the next orbital
