Answer:
Four types of molecules important for cell processes:
1. Proteins
2. Carbohydrates
3. Lipids
4. Nucleic Acids
Explanation:
Foremost, Molecules are groups of atoms that bonded and held together by chemical bonds - which form compounds. Cell processes all involve the interaction of molecules and atoms alike. These four groups are absolutely essential for every single organism on Earth. A cell and organism would not be able to live without these vital molecules.

salute vs the solvent a solvent is what a salute gets dissolved in
in this case the salute is the chocolate and the solvent is the water

Answer:
The student's conclusion is not correct
Explanation:
Activation energy is the minimum amount of energy required for a reaction to occur. All reactions require there activation energy to be met before the reaction can proceed. When the temperature of a reaction is increased, the kinetic energy of the reactant molecules increases; colliding more with each other, which makes them "surmount" the activation energy of the reaction faster as compared to a lower temperature.
In combustion, there is burning of an hydrocarbon (in this case propane) in excess oxygen. The burning assists in increasing the kinetic energy of the reactant particles which in turn easily surmounts the activation energy of the reaction by colliding (effective collision) more with oxygen. So, the reaction has an activation energy but the activation energy has been met and passed and hence the reaction is proceeding faster.
Increasing the temperature of a reaction is one of the ways of increasing the rate of a chemical reaction.
Answer:
Explanation:
molar mass of BaCl2 = 208.23
mol of BaCl2 = 8/208.22
mol of BaCl2 = 0.03841905
Molarity = 0.03841905/0.450
Molarity = 0.085 M
