Which of the following is one way that nuclear reactions differ from chemical reactions?
yuradex [85]

Answer:

The correct option is C.

Explanation:

Nuclear and chemical reactions are two types of reactions that one usually encounter in chemistry. These two reactions differ from each other significantly. For instance, the nuclear reactions usually involve the nucleus of the involving atoms while chemical reactions has to do with the electrons that are located outside of the nucleus of the atoms. Also, it is only chemical reaction that are influenced by factors such as temperature, pressure, catalyst, etc. Such factors does not determine the rate of nuclear reactions.

Consider the statement, “In a chemical reaction, atoms are neither created nor destroyed, only rearranged.” Why is this a statem
Karo-lina-s [1.5K]

Answer: The law of conservation of mass is reffering to the fact that energy cannot be created or destroyed. So when you speak about atoms not being created or destroyed it is the same thing. Unless you're talking about an atomic bomb where the atoms are split.

What volume of 0.555M KNO3 solution would contain 12.5 g of solute
Lorico [155]

The volume of 0.555M KNO3 solution would contain 12.5 g of solute iss 223 mL.

<h3>What is the relationship between mass of solute and concentration of solution?</h3>

The mass of solute in a given volume of solution is related by the formula below:

  • Molarity = mass/(molar mass * volume)

Therefore, volume of solution is given by:

Volume = Mass /molarity * molar mass

Molar mass of KNO₃ = 101 g/mol

Volume = 12.5/(0.555 * 101)

Volume = 0.223 L or 223 mL

In conclusion, the volume of the solution is obtained from the molarity of solution as well as mass and molar mass of solute.
