Answer:
Explanation:
Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules and ions. And The difference between Applied and Pure Sciences is that Applied Sciences focuses on the scientific knowledge of nature, it is more related to engineering and technology. Pure sciences is more related to theories and predictions to understand the world of nature, often performed in a laboratory.

Answer:
Just study the thing don't expect others to just answer the homework for you
Explanation:
If you truly are a good student then you should have asked your teacher in person or through email instead of asking on here. Not trying to be mean but you also have to understand that people on here have a life. :)
Magnesium oxide can be very bad for your health, and when we did an experiment with it in class it was white because it was so hot. It is very flammable.
Answer: (C) conservation of matter
Solution: Law of conservation of matter or mass states that' total mass of the reactants should always be equal to the total mass of the product that is the total mass is remained conserved in a chemical reaction.
A balanced chemical equation always follow this law.
For example:
Mass of hydrogen = 1 g/mol
Mass of Oxygen = 16 g/mol
Total mass on the reactants = 2(2×1)+(2×16)= 36g/mol
Total mass on the product side = 2[(2×1) +16] = 36 g/mol
As,
Mass on reactant side = Mass on the product side
Therefore, a balanced chemical reaction follows Law of Conservation of mass.
