B. Heat is a form of energy so boiling it would increase energy. (I guess)
Ba2+ and Cu2+, and Sr2+ and Li+
M/V=D
65.14/35.4≈1.84
The density of the sulfuric acid would be about 1.84g/mL
Answer:
90.3 L
Explanation:
Given data:
Volume of water produced = 77.4 L
Volume of oxygen required = ?
Solution:
Chemical equation:
2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O
It is known that,
1 mole = 22.414 L
There are 7 moles of oxygen = 7×22.414 = 156.9 L
There are 6 moles of water = 6×22.414 = 134.5 L
Now we will compare:
H₂O : O₂
134.5 : 156.9
77.4 : 156.9/134.5×77.4 =90.3 L
So for the production of 77.4 L water 90.3 L oxygen is required.
Answer:
(we use hess's law) it is so simple but the second reaction is not correct please right it
