Particles of carbon can also be called co2 or also a greenhouse gas. The emission of carbon into the atmosphere causes air pollution and can also lead to global warming.
Answer:
Ca: 1
Cl: 2
Explanation:
Since there is no subscript but there is the element, its assumed that there is at least 1, otherwise it would'nt be there
V=4.8 L
c=5.0 mol/L
M(Mg)=24.3 g/mol
1) n(HCl)=cv
2) m(Mg)=M(Mg)n(HCl)/2
3) m(Mg)=M(Mg)cv/2
m(Mg)=24.3*5*4.8/2=291.6 g
D.The sun does not rotate
I think it is D the last choice
