Which conclusion is best supported by the information?
sugar is a not considered a nonrenewable resource because it comes from living plants.
sugar is considered a nonrenewable resource because it comes from living plants.
sugar is not considered a nonrenewable resource because it is heated during processing.
sugar is considered a nonrenewable resource because it is heated during processing.

Sugar is considered a nonrenewable resource because it comes from living plants.

Explanation:

The conclusion that is best supported by the aforementioned information is SUGAR IS NOT CONSIDERED A NON RENEWABLE RESOURCE BECAUSE IT COMES FROM LIVING PLANTS. The correct option is A. Non renewable resources are those resources that can not be replaced by natural mean as the same rate at which it is consumed, for example oil, while renewable resources are those that can be easily replaced as they are consumed. In case of sugarcane plants, another one can be readily planted.

part 1: the half-life of the element is 22 years.

part 2: it will take 132.02 year for the sample to decay from 308.0 g to 4.8125 g.

explanation:

part 1: there are two ways to determine the half life time.

first way: the half life time can be determined directly from its definition as it is the time required for the sample to decay to its half concentration.

from the data the initial concentration was 45.0 g and decayed to its half value (22.5 g) in 22.0 years.

second way: the radio active decay is considered first order reaction so we can use the laws of first order reactions.

k = (1/t) ln (a/a-x), where k is the rate constant of the reaction,

t is the time of the reaction

a is the initial concentration of the reactant

a-x is the remaining concentration at time (t)

a = 45.0 g the initial concentration at t = 0 year.

at t = 22 year, a-x = 22.5 g

then k = (1/22 year) ln (45.0 g/ 22.5 g) = 0.0315 year-1.

the half-life time (t1/2) = ln 2/ k = 0.693/ k =0.693/ 0.0315 = 22 years.

part 2:

using the same law k = (1/t) ln (a/a-x),

using the given data; a = 308.0 g and a-x = 4.8125 g and the calculated k from the part 1 (k = 0.0315 year-1)

t = (1/k) ln (a/a-x) = (1/0.0315) ln (308.0/ 4.8125) = 132.02 years

the right answer is c i just did the question.
