The answer is 12g of Carbon
As your body needs more oxygen during exercising and produces more carbon dioxide, this might result in a high respiratory rate.
During exercise, your breathing may occur 3–4 times more frequently. Hyperpnea, or rapid, deep breathing, is the body's natural response to increased carbon dioxide generation. The pace of breathing increases along with the blood's concentration of carbon dioxide. The pH of the blood changes dramatically as carbon dioxide levels rise. The chemoreceptors in the medulla oblongata, a part of the hindbrain that controls respiration, detect this shift. To expel the additional carbon dioxide and breathe in more oxygen, the respiratory center speeds up breathing.

Answer:
6626 g
Explanation:
Given that:
Density of water = 1.00 g/ml, volume of water = 42800 ml.
Since density = mass/ volume
mass of water = volume of water * density of water = 42800 ml * 1 g/ml = 42800 g
Initial temperature of water = 22°C and final temperature of water = 45°C.
specific heat capacity for water = 4.184 J/g°C
ΔT water = 45 - 22 = 23°C
For iron:
mass = m,
specific heat capacity for iron = 0.444 J/g°C
Initial temperature of iron = 1445°C and final temperature of water = 45°C.
ΔT iron = 45 - 1445 = -1400°C
Quantity of heat (Q) to raised the temperature of a body is given as:
Q = mCΔT
The quantity of heat required to raise the temperature of water is equal to the temperature loss by the iron.
Q water (gain) + Q iron (loss) = 0
Q water = - Q iron
42800 g × 4.184 J/g°C × 23°C = -m × 0.444 J/g°C × -1400°C
m = 4118729.6/621.6
m = 6626 g
