Correctly identify the generic formula for a synthesis reaction.

a. ab + a+b
b. a+b → ab
c. cxhx + o2 → co2 + h2o
d. ab + c + ac + b
e. ab + cd → ad + cb

A + B → AB

Explanation:

Synthesis reaction:

It is synthesis reaction. The reaction in which two or more simple substance react to give one or more complex product.

A + B → AB

While,

E) Double replacement:

It is the reaction in which two compound exchange their ions and form new compounds.

AB + CD → AC +BD

Example:

The following reaction is double replacement reaction.

CaCO₃ + 2HCl  → CaCl₂ + H₂CO₃

A) AB → A + B

Decomposition:

It is the decomposition reaction. The reaction in which one reactant is break down into two or more product.

D) AB + C → AC + B

Single replacement:

It is the reaction in which one elements replace the other element in compound.

a polar bond is formed when electrons are shared unevenly between atoms

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
