Factories that produce cement account for around 5% of global emissions of carbon dioxide worldwide. Carbon dioxide is a greenhouse gas that absorbs solar radiation and rereleases it into Earth's atmosphere. Cement production has increased over time because the demand for cement has increased. Suppose that cement production continues to increase significantly over the next 50 years. Assuming that all other factors remain the same, what impact will this most likely have on the Earth?
A Gas other than carbon dioxide will become more concentrated in the atmosphere.
B Global temperatures on Earth will increase.
C Global temperatures on Earth will decrease.
D Gases other than carbon dioxide will become depleted in the atmosphere.

Global temperature of earth will increase

Explanation:

green house gases will trap. the heat and it will make our atmosphere warm.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
