A highly polar molecule that contains a weak bond between a hydrogen atom and another element would be a strong acid.
If the sperm carries a Y chromosome, it will result in a male. During fertilization, gametes from the sperm combine with gametes from the egg to form a zygote. The zygote contains two sets of 23 chromosomes, for the required 46.
1. <span>The phase change in which a substance changes from a liquid to a gas is condensation. The correct option among all the options given is option "c".
2. </span>The phase change in which a substance changes from a solid to a liquid is melting. The correct option among all the options given is option "b".
3. The phase change in which a substance changes from a solid to a gas or vapor without changing to a liquid first is sublimation. The correct option is option "a".
Because the alkali metals are the group 1 metals, they have only 1 valence electron that they want to lose, and the halogens are the group 17 nonmetals, they want to gain 1 valence electron to become stable.
Since pressure is connected to force, the force on a wall is
straightly proportional to the square of the velocity times the mass. The ratio
of the molecular weights of the CO2 and SO2 is (64.066 / 44.01) = 1.456. But,
we are not yet done. The actual rms velocity has to be taken as the square root
of that number, so the answer is 1.206.
