Answer:

Reactants

Explanation:

A combination reaction is usually defined as a type of chemical reaction in which two or more reactants are fused together to form a single product. For example, The two elements Hydrogen and Chlorine are linked together to form Hydrochloric acid.

This can be written as,

H + Cl -----> HCl (acid)

A decomposition reaction is usually defined as a type of chemical reaction in which a single and complex substance is disintegrated into two or more simple substances. For example, the same above reaction can be disintegrated into-

HCl (acid) ------> H + Cl

A physicist's right eye is presbyopic (i.e., farsighted). This eye can see clearly only beyond a distance of 97 cm, which makes
Ivan

Answer:

f = 19,877 cm   and  P = 5D

Explanation:

This is a lens focal length exercise, which must be solved with the optical constructor equation

        1 / f = 1 / p + 1 / q

where f is the focal length, p is the distance to the object and q is the distance to the image.

In this case the object is placed p = 25 cm from the eye, to be able to see it clearly the image must be at q = 97 cm from the eye

let's calculate

        1 / f = 1/97 + 1/25

        1 / f = 0.05

        f = 19,877 cm

the power of a lens is defined by the inverse of the focal length in meters

         P = 1 / f

         P = 1 / 19,877 10-2

         P = 5D
