In atmosphere there is 0.04 % of co2 in the air
In breath we breath out about 2 to 3 pounds of co2 which is greater than the amount of co2 found in air \
The sources of co2 are
respiration
combustion of organic fuels or compounds
CaCO3=100g
CaO=56g
56g of CaO=100g of CaCO3
1.12g of CaO= 100/56*1.12 g of CaCO3
=2g of CaCO3 (ans)
You would get green icing sugar.
Icing sugar is finely-ground sugar, and sugar is a neutral compound.
Universal indicator is green at pH 7 (neutral).
Answer:
pressure and temperature are directly proportional.
Explanation:
At constant temperature and pressure the volume of a gas is directly proportional to the number of moles of gas. Also given a constant temperature and volume the pressure of a gas is directly proportional to the number of moles of gas.
This means that if V is constant then
P = n (RT/V) then n= PV/RT. As P is increased, T is also increased thereby decreasing the value of n since pressure and temperature are directly proportional.
