Plz final grade before how many water molecules (h₂o) are there in this equation question 1 options: 1 2 4 6 question 2 (1 point) how many total carbon atoms are their in this equation? question 2 options: 1 2 4 6 question 3 (1 point) what does the law of conservation of matter/ mass state? question 3 options: mass cannot be created nor destroyed in a chemical reaction. mass can be created but not destroyed in a chemical reaction. mass can be destroyed but not created during a chemical reaction. mass can be created and destroyed during a chemical reaction. question 4 (1 point) what does conserving mass mean in a chemical equation? question 4 options: there are more of each type of atom on the product side than on the reactant side. there are more of each type of atom on the reactant side than on the product side. there is an equal number of each type of atom on the reactant and product side. there is an unequal number of each type of atom on both sides of the equation. question 5 (1 point) how many grams of hydrogen (h) would need to react with 190 grams of fluorine (f) to make 200 grams of hf (hydrofluoric acid)? question 5 options: 200 20 10 5 question 6 (1 point) is 2h2 + o2 →2h2o a balanced chemical equation? is it obeying the law of conservation of matter? question 6 options: no, the equation is not balanced. the oxygen (o) in the equation has less atoms represented on the products. yes, the equation is balanced. there are the same number of hydrogen (h) and oxygen (o) atoms on both sides of the equation. no, the equation is not balanced. the hydrogen (h) in the equation has less atoms represented on the products. question 7 (1 point) is 2h + o2 →2h2o a balanced chemical equation? is it obeying the law of conservation of matter? question 7 options: no, the equation is not balanced. the oxygen (o) is not balanced, but the hydrogen (h) is. no, the equation is not balanced. neither the hydrogen (h) nor the oxygen (o) are balanced. yes, the equation is balanced. the hydrogen (h) and oxygen (o) atoms are equal on each side of the equation. no, the equation is not balanced. the hydrogen (h) is not balanced, but the oxygen (o) is. question 8 (1 point) the underlined portion of the chemical formula above represents the which tells question 8 options: coefficient; how many hydrogen atoms there are in one molecule coefficient; how many water molecules there are subscript; how many water molecules there are subscript; how many hydrogen atoms there are in one molecule question 9 (1 point) the blue underlined part of the chemical formula above represents a(n) question 9 options: molecule coefficient subscript equation question 10 (1 point) what is the number in a chemical formula that tells the number of specific atoms in the molecule? question 10 options: coefficient molecule subscript formula
