The appropriate answer is a. Increased consumption of beef which increases methane production. Increases in the number of cases of heat exhaustion will be caused by increases in temperature as a result of the exacerbation of the greenhouse effect which leads to global warming. Cattle production produces large quantities of methane as a result of the process of digestion in these animals. Methane, like carbon dioxide is a greenhouse gas however it traps more heat than carbon dioxide. Methane production as a result of livestock rearing will be the cause of the increased cases because it is practiced on a very large scale. Burning plastics and using cfcs do release greenhouse gases but on a much smaller scale.
Using solar panels instead of fossil fuels will actually reduce the greenhouse gases if done on a large scale.
The question above is incomplete, the options attached to the question are listed below:
A.
Hydrogen effuses 1.4 times faster than helium.
B.
Hydrogen effuses 0.71 times faster than helium.
C.
Helium effuses 1.4 times faster than hydrogen.
D.
Helium effuses 0.71 times faster than hydrogen.
E.
The rate of effusion of both gases is the same.
ANSWER
The correct answer is D.
The rate of effusion of an element refers to the rate at which a gas will escape through a small role. The effusion rate of a gas is inversely proportional to the square root of the mass of its particles.
Effusion rate = rate of hydrogen / rate of helium
Effusion rate = 2^1/2 /4^1/2 = 1/2^1/2
Effusion rate = square root of 1/2 = 0.71.
By providing the heat to the ice th closely packed particles of it gain kinetic energy and move away from each other so it melts
Answer:
4
Explanation:
How many neutrons in total were produced by the two
8.7M Is the solubility of Ca(oh)2 in water at a given Ksp of 6.5 .10-6 and molar mass of 74.09g/mol.
Solubility is defined as the amount of the substance dissolved in a given amount of solvent at a certain temperature.
Ca(OH)2 à Ca2+ + 2OH-
Ksp = 6.5 .10-6
Molar mass= 74.09 g/mol
Ksp is solubility product constant which describes the equilibrium between a solid and its ion in solution.
Ksp=[Ca2+] [OH2-]
6.5 .10-6 = S. (74.09g/mol +S)
6.5 .10-6 = S .( 74.09M)
S = 6.5 .10-6 /74.09 M
= 8.7 M
So, the solubility of Ca(OH)2 is 8.7M.
