Answer:
atomic mass ( N =14 , H = 1×3 that means 14+3=17
340gram×17gram / mole
=5780mole
atomic mass ( H= 1×2 ,O= 16 =16+2 =18
90gram×18gram /mole
=1620mole
I think 340g ammonia (NH3)
Answer:
Explanation:
Using Gay Lusaac's law where there is no change in Volume. The pressure changes directly proportional to absolute T°
P₁/T₁ = P₂/T₂
P₁T₂/T₁
P₂ =
P₂ =
1. A 2. D 3. C 4. B are the answers
Answer:
Plastic is an insulator
Explanation:
This enables you to touch it without burning yourself because it does not conduct heat easily.
The value of x : 2
<h3>Further explanation</h3>
Semi-normal Hydrochloric acid solution = 0.5 N = 0.5 M
for titration :
M₁V₁n₁=M₂V₂n₂(1=HCl,2=Na₂CO₃)
MW Na₂CO₃.xH₂O=143
MW Na₂CO₃.xH₂O = MW Na₂CO₃+ MW xH₂O = 143
MW Na₂CO₃ = 106 g/mol
MW xH₂O = 18x
Equation :
