Total mass of CaCO3 = 40 amu of Ca + 12amu of C + 16×3 amu of oxygen = 100amu of CaCO3
i.e 100 tonnes of CaCO3 .
mass of CO2 = 12amu of C + 2× 16amu of O = 44 amu of CO2
mass % of CO2 in CaCO3 = (44/100)×100 =44%
i.e
44% of 100 tonnes is CO2.
=44 tonnes of CO2.
therefore, 44% of CO2 is present in CaCO3.
Answer:
An ionic compound is a giant structure of ions.
Explanation:
As a result of ion attraction, ions form a regular pattern with oppositely charged ions next to each other in an ionic compound. Ions are organized in an ionic network, a giant structure made up of alternating ions.
Answer:
Explanation:
Hello,
In this case, considering that the density of a body is computed given its mass and volume:
Taking into account that the mass is 24.32 g and the volume is computed via the difference between the volume of the water with the brass and the volume of water by itself as follows:
The density of the piece of brass turns out:
Best regards.
For precipitation to happen, first tiny water droplets must condense on even tinier dust, salt, or smoke particles, which act as a nucleus. Water droplets may grow as a result of additional condensation of water vapor when the particles collide. If enough collisions occur to produce a droplet with a fall velocity which exceeds the cloud updraft speed, then it will fall out of the cloud as precipitation.
Removing chloride ion is the reaction away
