How many neutrons does element X have if its atomic number is 31 and its mass number is 80?
MrRissso [65]

49 neutrons in each nucleus.

<h3>Explanation</h3>

For each nucleus:

Mass number = Number of protons + Number of neutrons.

The atomic number of a nucleus is the same as its number of protons. The atomic number of the nucleus here is 31. There are 31 protons in each nucleus.

  • Mass number = 80;
  • Number of protons = Atomic number = 31;
  • The number of neutrons is to be found.

Again,

Mass number = Number of protons + Number of neutrons.

80 = 31 + Number of neutrons.

Number of neutrons = 80 - 31 = 49.

During a change of state, the temperature of a substance _____.
Natali5045456 [20]
Hello,

Your questions states:

During a change of state, the temperature of a substance _____?

In which you gave us some choices:

A. decreases if the arrangement of particles in the substance changes.
B. remains constant until the change of state is complete.
C. increases if the kinetic energy of the particles in the substance increases.
D. increases during melting and vaporization and decreases during freezing and condensation.

Your answer would be:

B. remains constant until the change of state is complete.

Your explanation/Reasoning:

It absorbs the energy, then after the phase changes it then increases the temperature all over again.

Have a nice day:)

Hope this helps!

How many moles of chloride ions are there in 2.5 L of 5 M magnesium chloride?
castortr0y [4]

Answer:

n_{Cl^-}=25molCl^-

Explanation:

Hello,

In this case, since the given 5-M concentration of magnesium chloride is expressed as:

5\frac{molMgCl_2}{L}

We can notice that one mole of salt contains two moles of chloride ions as the subscript of chlorine is two, in such a way, with the volume of solution we obtain the moles of chloride ions as shown below:

n_{Cl^-}=5\frac{molMgCl_2}{L}*\frac{2molCl^-}{1molMgCl_2} *2.5L\\\\n_{Cl^-}=25molCl^-

Best regards.
