The amount of energy that was used to heat Cu is 27.6 cal
<u><em>calculation</em></u>
Heat (Q) = M ( mass) x c(specific heat capacity) x ΔT( change in temperature)
where;
Q=?
M = 5.0 g
C=0.092 cal/g°C
ΔT = 80°c-20°c=60°C
Q is therefore = 5.0 g x 0.092 cal / g°c x 60°c =27.6 cal
In an acidic solution, the rate change if Sucrose is changed to 2.5 M will be Rate = k[H⁺][2.51M] as the initial rate of sucrose breakdown is measured in a solution that is 0.01 M H⁺.
<h3>What is the breakdown of sucrose?</h3>
Sucrose is a type of sugar that is made by adding fructose and glucose or the breakdown of fructose will be in the form of glucose and fructose always at different levels of concentration.
In the given acidic solution if the concentration of sucrose changes from 0.01 to 2.5 then both have to add to give the total rate of change in the given reaction and it will be 2.51 M.
Therefore, Rate = k[H⁺][2.51M] as the initial rate of sucrose breakdown is measured in a solution that is 0.01 M H⁺for an acidic solution, the rate change if Sucrose is changed to 2.5 M.

Answer: The number of moles of 
produced are, 0.287 moles.
Explanation : Given,
Mass of 
= 14.9 g
Molar mass of = 32 g/mol
First we have to calculate the moles of
Now we have to calculate the moles of
The balanced chemical equation is:
From the reaction, we conclude that
As, 13 mole of react to give 8 moles of
So, 0.466 mole of react to give 
mole of
Therefore, the number of moles of produced are, 0.287 moles.
Answer:
This is called the pulmonary circulation. From your pulmonic valve, blood travels to the pulmonary artery to tiny capillary vessels in the lungs. Here, oxygen travels from the tiny air sacs in the lungs, through the walls of the capillaries, into the blood.
Explanation:
