Answer:

C

Explanation:

A solution is made when solute is dissolved in a solvent. Take a simple scenario for example, a salt solution typically is comprises of a an amount of salt mixed with a certain volume of water. The mixture of both is what makes a salt solution.

In this case, we need to make a solution if sweetened coffee. Prior to now, we know we have a particular coffee which is unsweetened that is has no sugar in it. Now, we are tasked with the responsibility of making a sweetened coffee. Our coffee is without sugar thus will serve as the solvent because it is the carrier medium. The sugar which obviously would dissolve in the solvent to form a solution would be our solute.

Now dissolving it in the unsweetened coffee thus will give us a sweetened coffee solution.

(Answer) (d) Chemical reaction rates vary with the conditions of the reaction, but nuclear decay rates do not.

Rate of a chemical reaction refers to rate of formation of products from reactions during a chemical reaction. The rates of chemical reactions depend on various factors such as temperature, pressure, concentration of reactants, presence of catalyst etc. For this reason, chemical reaction rates vary with the conditions of the reaction.

Nuclear decay rate refers to the constant ratio of the number of atoms of radioactive nucleus that decay during a certain interval of time to the total number of radioactive atoms at the beginning of the time interval. Nuclear decay rates are constant and do not vary with the conditions of the reaction.

Newly formed atoms, more neutrons, and kinetic energy are all:
Zinaida [17]

Answer:

The correct answer is - C. products of nuclear fission reactions.

Explanation:

Nuclear fission is one of the nuclear reactions in which a heavy nucleus of the atom splits due to the impact of another particle or substance or it is on its own. In this reaction, there is a huge amount of kinetic energy released with more neutrons as the nucleus splits neutrons produced with energy.

The products of this reaction is newly formed atoms, kinetic energy and more neutrons and reactants is the heavy nucleus of the atom used.
