Radon-219 decays to radon-218 by releasing... a. a positron b.a muon O c. a neutron O d. an electron O e. a proton
MrRa [10]

Answer: Option (c) is the correct answer.

Explanation:

A positron is denoted as ^{0}_{+1}e, a neutron is denoted as ^{1}_{0}n, an electron is denoted as ^{0}_{-1}e, and a proton is denoted as ^{1}_{1}p.

Therefore, when ^{219}Rn will decay into ^{218}Rn this means there occurs decrease in its mass number. Hence, it means a neutron will be releasing during this reaction.

The reaction will be as follows.

                ^{219}Rn \rightarrow ^{218}Rn + ^{1}_{0}n

A 50.0 mL sample of 12.0 M HCl is diluted to 200 mL. What is true about the diluted solution?
kobusy [5.1K]

The concentration of the solution reduces and the number of moles of solute isn't affected.

Data;

  • V1 = 50mL
  • C1 = 12.0M
  • V2 = 200mL
  • C2 = ?
<h3>Facts about the diluted solution</h3>

1. When the solution is diluted, the concentration changes and this time, the concentration reduces.

Using dilution formula

c_1 v_1 = c_2 v_2\\12 * 50 = c_2 * 200\\c_2 = \frac{600}{200} \\c_2 = 3M

The concentration of the solution reduces.

2. The number of moles remains the same.

When a solution is diluted, the number of moles remains the same because there's no change in the mass of the solute.
