Answer: The Earth is an oblate spheroid which is more elongated along the equator.
Regions along the equator receives more amount of direct sunlight from the sun causing higher temperatures along the region. While places along the poles receives less amount of heat since heat is scattered in a larger area due to the shape of the Earth around the poles.
Explanation: So places along the equator experiences higher temperature due to the direct hit of sunlight. And places along the polar regions experiences cooler temperature since it receives less amount of sunlight.
The correct answers :
It increases with a decrease in the concentration of H₂(g).
It decreases with an increase in the concentration of S₂(g).
It decreases with an increase in the concentration of H₂(g).

Forward reaction : rate to form product
In equilibrium :
The product decreases ⇒ system will move from left to right(forward reaction)
The product increases ⇒ system will move from right to left(reverse reaction)

Answer:
(C) substance B is not involved in the rate-determining step of the mechanism but is involved in subsequent steps.
Explanation:
A. Is incorrect because if the order of the reaction with respect B was one then the rate would increase by the same multiple that B is increased by.
B. If B is reactant then it must be involved in the mechanism of the reaction and in the formation of the product
D. If B was a catalyst then increasing it's amount would affect the rate
E. That is just factually untrue. Effect of reactants on rates can only be found experimentally, not stoichiometrically.
Answer:
360.4 grams
Explanation:
The first step is to find the molecular mass of H2O. The molecular mass of a molecule is the atomic masses added altogether. Because there are 2 hydrogens, we need 2x the atomic mass. 2(1.01) + 1(16.00) = 18.02 amu.
The molar mass of H2O is 18.02 g/mol. This is the unit converter to change from moles to grams
