Answer:
B) P₂O₅
Explanation:
A) MgCl₂
Molar mass of Mg = 24
Molar mass of Cl = 35.5
Molar mass = 24 + 2×35.5 = 95 g/mol
B) P₂O₅
Molar mass of P = 31
Molar mass of O = 16
Molar mass = 31 ×2 + 5×16 = 142 g/mol
C) BaCl₂
Molar mass of Ba = 137.33
Molar mass of Cl = 35.5
Molar mass = 137.33 + 2×35.5 = 208.33 g/mol
D) AlCl₃
Molar mass of Al = 27
Molar mass of Cl = 35.5
Molar mass = 27 + 3×35.5 = 133.5
Explanation:
chemical compound, any substance composed of identical molecules consisting of atoms of two or more chemical elements. All the matter in the universe is composed of the atoms of more than 100 different chemical elements, which are found both in pure form and combined in chemical compounds

Answer:there butt and other stuff you know what I am saying
Explanation:
The earth’s plates sliding against each other and moving under each other causes earthquakes. When plates move apart, magma comes up, thus forming a volcano.
