A is incorrect as some ionic compounds can be stronger than covalent compounds.
Answer:
1.5 moles
Explanation:
Given data:
Number of moles of O₂ consumed = 2.5 mol
Moles of CO₂ produced = ?
Solution:
Chemical equation:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
Now we will compare the moles of oxygen with carbon dioxide from balance chemical equation:
O₂ : CO₂
5 : 3
2.5 : 3/5×2.5 = 1.5
Thus from 2.5 moles of oxygen 1.5 moles of carbon dioxide are produced.
Answer:
SnH4
Explanation:
Because the melting point of SnH4 is higher than CH4
1L ------------ 1 kg
? ------------- 3.8 kg
3.8 x 1 / 1
= 3.8 L
Answer:
¾ litters of water was consumed
2.24 litters = 1 mole of water
Therefore ¾÷2.24 moles was consumed
0.33 moles
