7. ## Science

How is the law of conservation of mass used to balance a chemical equation? In a chemical equation, the products formed have the same atoms as the original reactants; however, the atoms may be rearranged. The law of conservation of mass states that the

8. ## Science

9. ## Science

What is a synthesis reaction? a reaction that occurs when one element within a compound is exchanged with another element a reaction that occurs when a single substance breaks apart and forms two or more new substances a reaction that occurs when a

10. ## Science

Why do some chemical reactions occur? Select all that apply. so the particles can have less energy so the particles can turn into gas so the particles can have less volume so the particles can be more spread out

11. ## Science

What is a factor that drives chemical reactions? tendency to have less energy tendency to have less mass tendency to burn tendency to condense Tends to burn right?

12. ## Science

If Ag2O decomposes, what is the balanced equation that shows the products formed? Ag2O(s) → 2Ag(s) + O(g) 2Ag2O(s) → 4Ag(s) + 2O(g) Ag2O(s) → Ag2(s) + O(g) 2Ag2O(s) → 4Ag(s) + O2(g) would it be 2Ag2O(s) → 4Ag(s) + 2O(g)?

13. ## Math

Jamal wants to know if x−3 is a factor of the polynomial P(x)=x3−7x+6. Jamal calculates P(3) and applies the Factor Theorem to conclude that x−3 is a factor of P(x). Is he correct? Why or why not? No, because P(3) is equal to 0. No, because P(3) is

14. ## Science

What is the oxidation state of an element? the total number of protons an atom can gain or lose during a chemical reaction the total number of electrons an atom loses or gains during a chemical reaction the number of elements oxygen can bond with to form a

15. ## Chemistry

Magnesium has two valence electrons and oxygen has six valence electrons. The electronegativity difference between the two elements is 2.13. How can the octet rule be used to explain the bonding between magnesium and oxygen? Oxygen needs access to two

16. ## Science

How can the relationship between synthesis and decomposition reactions be described? Synthesis reactions happen when substances combine to make a new substance. Decomposition reactions occur when a substance breaks apart to make new substances. Thus, the
