Answer:
coral bleaching is when the temperature of the water changes (even slight changes in temperature effect coral) and the coral reacts negatively to it causing it to die. unfortunately corals cannot recover once they have been bleached.
Answer:
I'm just guessing/deducting here, but:
1. Because the electronegativity of silicon is much stronger causing electrons to be much less conducive.
2. Extra free electrons = is more charged particals that can move freely and thus conduct electricity. So the resistivity will be lowered.

Answer:
B
Explanation:
Statement A
Vrms (root-mean-square velocity) is defined as follows.
Vrms = √(2RT/Mm), where R is the ideal gas constant, T is the temperature, and Mm is the molar mass of the gas. R and T are the same for both gases, but the molar mass is different, so Vrms for the two gases is different
Statement B
Kinetic energy KE of a molecule is related to temperature as follows:
KE = 3/2KbT, where Kb is the Boltzmann's constant and T is the temperature. The temperature is the same for both gases, so KE is the same for both.
Statement C
The rate depends on the number of molecules present. Since there are twice as many molecules of methane as propane, the rate is different for both gases.
Statement D
Pressure is directly proportional to the number of moles, based on the ideal gas law (pV = nRT). The volume and temperature are the same for both gases, so since there are twice as many molecules of methane as propane, the pressure is twice as great in the cylinder of methane.

The coffee is the solvent. The sugar is the solute. The sweetened coffee is the solution.
