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 :
B. A solid forms when two liquids are mixed
Answer: I do think that neighborhoods are an ecosystem
Explanation: a ecosystem contains living and non-living things, some examples are the people,plants,and pets are living organisms and the houses and the street lamps are non living. Therefore making a neighborhood a ecosystem
Answer:
used for making sari obtained from animal is silk
<span>2CH</span>₃<span>OH + 3O</span>₂<span> → 2CO</span>₂ + <span> 4H</span>₂O
mole ratio of CO₂ : H₂O is 2 : 4 (simplified as 1 : 2)
∴ if moles of CO₂ = 3.25 moles
then moles of H₂O = 3.25 moles × 2
= 6.50 moles
