Hello friend ☺
ΔH = MCΔT
ΔH = to the amount of energy or change in energy (J)
mass of water
C = waters specific heat capacity
ΔT = change in temperature
and so ΔH = 25 × 4.18 × ( 112-67 ) J = 4702.5 J
Thanks ❤
Elements in the same group have the same amount of electrons.
Elements in the same period have the same amount of atomic orbits.
Hope this helps!
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.
Answer:
Compounds with Carbonate ions are less soluble than the compounds with Chlorate ions.
Explanation:
The reason is that the compounds with carbonate ions have less attraction between positive and negative charges. (Solvation)
