Answer: a) 
: Decomposition
b) 
: double displacement
c) 
: Synthesis (Combination)
d) 
: redox
Explanation:
Decomposition is a type of chemical reaction in which one reactant gives two or more than two products.
A double displacement reaction is one in which exchange of ions take place.
Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.
Redox reaction is a type of chemical reaction in which oxidation and reduction takes place in one single reaction. The oxidation number of one element increases and the oxidation number of other element decreases.
the refractive index of the liquid is 1.476
The refractive index, which has no dimensions, measures how quickly light passes through a substance.
It can also be described as the difference between the speed of light in a vacuum and a medium.
Refractive index is equal to the product of the light's liquid and vacuum speeds.
Therefore.
speed of light in vacuum = 4.96 km/t
speed of light in liquid = 3.36 km/t
Refractive index = 4.96/3.36
Refractive index =1.476
Therefore, the refractive index of the liquid is 1.476

Answer:
having a smooth or lubricated surface may help decrease friction.
Explanation:
Answer:
The acceleration of the object equals the gravitational acceleration. The mass, size, and shape of the object are not a factor in describing the motion of the object. So all objects, regardless of size or shape or weight, free fall with the same acceleration
