Answer:
it will become heterogenous and as well asit will dissociate into ions
also it will form base and evolve h2gas
The Milliliters that occupy when its pressure is 755 mmhg is calculated using Bolyes law fomula
that is P1v1 = p2 V2
p1= 735mmhg
V1= 350 Ml
P2= 755 mm hg
V2= ?
from the formula above V2 is therefore= p1V1/P2
= 350 x735/755= 340.73 Ml
Answer:
First one c for the second one i think is c sorry if wrong hope this help
Explanation:
Answer:
7 moles
Explanation:
The molecular formula of sodium sulfide is Na_2S
One molecule of Sodium sulfide has 2 atoms of sodium and one atom of sulfur
1 mole of Sodium sulfide has 2 moles of sodium and one mole of sulfur
so 3.5 moles of sodium sulfide will have 2× 3.5 moles of sodium atoms
i.e 2×3.5= 7 moles of sodium atom
