Answer:
153.8 g/mol.
Explanation:
The molar mass of a compound = ∑ atomic masses of atoms.
<em>∴ The molar mass of CCl₄ = 1(atomic masss of C) + 4 (atomic mass of Cl) </em>= (12.0 g/mol) + 4 (35.45 g/mol) = <em>153.8 g/mol.</em>
Batteries come in all shapes and sizes, and depending on the type of battery, the minerals that compose them are mainly lithium, cobalt, graphite, nickel and manganese.

Explanation:
Structural geometry is the key to understanding particle-particle interactions on a physical levels. Suggest a review of molecular geometry and states of matter for a more in depth understanding. Doc
Because flame provides a source of heat so that the magnesium metal atoms can overcome their activation energy. Activation energy is the minimum energy required in order for a chemical reaction to proceed. When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide.
Answer:
Mass is the amount of matter in an object.
Weight is how much an object weighs.
