Answer:
Any Alkali Earth Metal - Group 2A aka Group 16 or polyatomic cation with a 2+ charge
The answer to this question is A
Answer:
The atoms on left side are larger than the atoms on the right side of the periodic table because those on the right have more proton's.
Explanation:
As we travel along a period in a periodic table then the atomic radii decreases
This is because as we travel along a period we have that the atomic number of the atoms increases which means the the number of proton's increased
But the electron's add to the same outer shell throughout the period , which means the effective nuclear charge increases which pulls the outer electrons toward's the nucleus and the size decreases.
Therefore the atoms on left side are larger than the atoms on the right side of the periodic table because those on the right have more proton's.

Answer : The mass of carbon and oxygen produced is 8.83 g and 23.6 g respectively.
Explanation :
Law of conservation of mass : It states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
This also means that total mass on the reactant side must be equal to the total mass on the product side.
The balanced chemical reaction will be,
As we are given:
According to the law of conservation of mass,
Total mass of 
= Mass of 
+ Mass of C
Total mass of = 2.67 + 1 = 3.67 g
Now we have to calculate the mass of and C.
and,
Therefore, the mass of carbon and oxygen produced is 8.83 g and 23.6 g respectively.
