Answer: D) Monitor the sea level over set period of time.
Since global warming causes land ice to melt, that water goes into the ocean to raise sea levels. This is an effect of global warming.
Choices A through C are things to measure if you want to measure causes of global warming, so we can rule those out.
Answer: For the given reaction an increase in the forward reaction rate due to increase in the number of effective collisions.
Explanation:
According to the rate law, rate of a reaction depends on the concentration of its reactants. So, more is the number of reactants then more will be the number of collisions taking place.
As a result, more will be the amount of product formed. For example, in the reaction 
an increase in 
means an increase in the number of reactants.
Hence, more is the number of collisions taking place leading to more amount of formation of products.
Thus, we can conclude that for the given reaction an increase in the forward reaction rate due to increase in the number of effective collisions.
1 mol of any substance is made of 6.022 x 10²³ units, these units could be atoms making up elements or molecules making up a compound.
In this case. 1 mol of Li is made of 6.022 x 10²³ atoms of Li
The molar mass of Li is 6.94 g/mol
Therefore mass of 1 mol of Li is 6.94 g
In 6.94 g of Li there are - 6.022 x 10²³ atoms
Then in 766.3 g of Li there are - 6.022 x 10²³ atoms / 6.94 g x 766.3 g = 665 x 10²³
There are 6.65 x 10^25 atoms of Li
First,let's assume ideal gas behavior for simplicity. This is a special case because the volumes of the two states are equal. At constant volume, we can use the Gay-Lussac equation:
P₁/T₁ = P₂/T₂
(0.8)/(127+273) = (P₂)/(27+273)
Solving for P₂,
P₂ = 0.6 atm
<em>Thus, the answer is 0.6 atm.</em>
