The answer is acetic acid
Answer:
The pressure decrease with the passage of time due to again dissolution of carbon-dioxide gas in the liquid solution.
Explanation:
In soft drinks, the carbon-dioxide gas is added in the drinks with high pressure because carbon-dioxide is a gas which is insoluble in soft drink at room temperature but soluble in the drinks at high pressure so when the pressure is removed from the soft drink, the carbon-dioxide gas releases in the air with the passage of time. But in close bottle , there is no place of escape so it again dissolve in the solution.
Answer:
7,881 g/L
Explanation:
Iron volume = 30.58 mL - 29.40 mL = 1.18 mL
1.18 mL / 1000 mL = 0.00118 L
Iron density = mass/volume
= 9.3g / 0.00118 L
= 7,881 g/L
It’s A. Land heats up and cools quickly then water
Answer:
4.55 mol of C₂H₂
Explanation:
Let's verify the reaction:
CaC₂ + 2H₂O → C₂H₂ + Ca(OH)₂
Ratio is 1:1, so 1 mol of calcium carbide will produce 1 mol of acetylene.
4.55 mol of CaC₂ will make the same amount of C₂H₂
