Cl₂
Explanation:
The gas with the highest molecular mass will be considered the heaviest of all of them.
To solve this problem, we must calculate the molecular mass of the given gases;
O₂ CH₄ CO₂ and Cl₂
O₂ molecular mass = 15.9998 x 2 = 32g/mol
CH₄ = 12 + 4(1) = 16g/mol
CO₂ = 12 + 2(16) = 44g/mol
Cl₂ = 2(35.5) = 71g/mol
The heaviest of the gases given is Cl₂ because it has the highest molar mass compared to other gases.

Answer: Protons
WHY?
Changing electrons will only result in the same element having different charges and hence, changing it's chemical properties.
Changing neutrons will not change an element but it will result in an isotope forming instead. (Isotopes are elements of the same type with different neutron numbers.)
However, changing the proton number would immediately change the nucleus composition, resulting in a change in element with a negative charge as there are more electrons than protons. This results in a expansion in valance electrons's distance from the nucleus. This results in a change in chemical properties of the element.
Therefore, a change in Protons is the answer.
Answer: 44,8 l. of CO2 and 72 g. of water will be produced
Explanation:
He answers is B It equals the rate of the formation of SO3
Answer
Hi,
In this equation, i see we have two answers;
B. Magnesium loses two electrons
C. Chlorine gains one electron
Explanation
Due to their valences, Magnesium,Mg+2 and Chlorine -1, magnesium atom will loose two electrons to form a stable state 2+ ions.Chlorine as a member of group 7 elements of the periodic table, the chlorine atom will gain 1 electron to form a stable 1- ion and facilitate the formation of the ionic bond that occurs between the two elements.
