The effective nuclear charge is the net positive charge experienced by valence electrons
Answer:
Explanation:
2Al + 3Cl2 --> 2AlCl3
Ag2O + Be -----> 2Ag + BeO
4K + O2 ---> 2K2O
CoP + 3NaBr ---> CoBr3 + Na3P
Si + Hg2S ---> SiS2 + Hg
6Li + Ni3N2 --- > 2Li3N + 3Ni
3Ca + 2K3N --> Ca3N2 + 6K
SnS2 + 2F2 --> SnF4 + 2S
The moles of O2 that are needed to react completely with 35.0 mol C2H2 is 87.5 moles of O2
<u><em>Explanation</em></u>
Write a balanced chemical equation for reaction of between C2H2 and O2
2 C2H2 + 5O2 → 4 CO2 + 2 H2O
if 35.0 moles C2H2 reacted then use the o mole ratio to determine the moles of C2H2
The mole ratio of C2H2 :O2 = 2:5 therefore the moles of O2
= 35 moles x5/2 = 87.5 moles of O2
Answer:
Feather
Explanation:
A feather is a solid which doesn't change its shape or size.
Carbon Dioxide and Oxygen are both gases that don't have a fixed size or shape.
Milk is a liquid which can change its shape but not size.
