50 pts and bra8inliest if u get it right and answer all
question 1 options:
indicate whether the reaction is an example of a synthesis, decomposition, combustion, single displacement or double displacement reaction. na3po4+3kohànaoh+k3po4
i think it might be double displacement but im not sure
question 2
name the reactants in the reaction from question 1. separate the reactants with a comma. do not use subscripts. for example, if the reactants are nh3 and h2o the answer would be entered as: nh3, h2o
i think its napo4 but im not sure
question 3
name the products in the reaction from question 1. separate the products with a comma. do not use subscripts. for example, if the products are nh3 and h2o the answer would be entered as: nh3, h2o
i think its naoh, k3po4 but im not sure
question 4
indicate whether the reaction is an example of a synthesis, decomposition, combustion, single displacement or double displacement reaction. c6h12+9o2à6co2+6h2o
question 5
name the reactants in the reaction from question 4. separate the reactants with a comma. do not use subscripts. for example, if the reactants are nh3 and h2o the answer would be entered as: nh3, h2o
i think its c6h12o6, 6o2 but im not sure
question 6
name the products in the reaction from question 4. separate the products with a comma. do not use subscripts. for example, if the products are nh3 and h2o the answer would be entered as: nh3, h2o
i think its 6co2,6h2o but im not sure
question 7
indicate whether the reaction is an example of a synthesis, decomposition, combustion, single displacement or double displacement reaction. pb+feso4àpbso4+fe
question 8 (
indicate whether the reaction is an example of a synthesis, decomposition, combustion, single displacement or double displacement reaction. caco3àcao+co2
question 9
indicate whether the reaction is an example of a synthesis, decomposition, combustion, single displacement or double displacement reaction. p4+3o2à2p2o3
question 10
indicate whether the reaction is an example of a synthesis, decomposition, combustion, single displacement or double displacement reaction. c3h6o+4o2à3co2+3h2o
question 11
balance the following equation to satisfy the law of conservation of mass. nai + pb(so4)2 àpbi4+ na2so4 enter the coefficients in order from left to right, separated for a comma. if there is no coefficient, use a 1. example: h2+o2àh2o is balanced as 2h2+o2à2h2o enter the answer as 2,1,2 question 12
balance the following equation to satisfy the law of conservation of mass. fe(oh)3à fe2o3+ h2o enter the coefficients in order from left to right, separated for a comma. if there is no coefficient, use a 1. example: h2+o2àh2o is balanced as 2h2+o2à2h2o enter the answer as 2,1,2 question 13

predict the products of the following reaction: nai+cacl2à separate the products with a comma. do not use subscripts. for example, if the products are nh3 and h2o the answer would be entered as: nh3, h2o
question 15
predict the products of the following reaction: li+ kno3à (lithium is above potassium on the activity series for metals) separate the products with a comma. do not use subscripts. for example, if the products are nh3 and h2o the answer would be entered as: nh3, h2o
question 16
5 points extra credit
predict the products of the following reaction: rbno2 +baco3à separate the products with a comma. do not use subscripts. for example, if the products are nh3 and h2o the answer would be entered as: nh3, h2o if needed for polyatomic ions, use parenthesis. example: al(no3)3 should be entered as al(no3)3

Explanation:
Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.
Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.
Double displacement reaction is defined as the reaction where exchange of ions takes place. Double displacement reaction in which one of the product remain in solid form are represented by (s) after their chemical formulas. Such double displacement reaction are called as precipitation reaction.
Double displacement reaction is defined as the reaction where exchange of ions takes place.
Single displacement reaction is defined as the reaction where more reactive element displaces a less reactive element from its chemical reaction.
Decomposition reaction is defined as the reaction where a single substance breaks down into two or more simpler substances.
Synthesis/Combination reaction is defined as the reaction where substances combine in their elemental state to form a single compound.
