Answer:
3) H-O
Explanation:
because oxygen and hydrogen have very high difference in electronegativity
Answer:
10.6 moles of CO₂ are produced in this combustion
Explanation:
The combustion reaction is:
2C₂H₆ (g) + 7O₂ (g) ⟶ 4CO₂ (g) + 6H₂O (g)
We assume the ethane as the limiting reactant because the excersise states that the O₂ is in excess.
We make a rule of three:
2 moles of ethane can produce 4 moles of CO₂
Therefore 5.30 moles of ethane will produce (5.3 . 4) /2 = 10.6 moles
The answer to that question would be C
Answer:
The large relative distances between particles in a gas means that there is considerable empty space between the particles.
The assumption that particles in a gas are relatively far apart explains gas compressibility.
Compressibility is a measure of how much the volume of matter decreases under pressure.
Energy is released by a gas when it is compressed
Explanation:
The kinetic molecular theory establishes that gases are composed of molecules. These molecules of gas are far apart from each other hence there is a considerable empty space between the gas molecules. As a result of these empty spaces between gas molecules, it is possible to compress a gas.
Compressibility is defined as a measure of how much the volume of matter decreases under pressure. When a gas is compressed, work is done on the gas and energy is evolved hence the gas heats up.
