<u>Answer:</u> The chemical equation is written below.

<u>Explanation:</u>

When chromium metal reacts with chlorine gas, it leads to the production of chromium chloride.

The chemical equation for the formation of chromium chloride follows:

2Cr(s)+3Cl_2(g)\rightarrow 2CrCl_3(s)

This is a type of combination reaction because two small substances react to form one large substance.

Hence, the chemical equation is written above.

180m/173 Tl -&gt; 180/173 Tl + ? Express your answer as a nuclear equation ​
Law Incorporation [45]

Answer: The nuclear equation is ^{180}_{173}Tl \rightarrow ^{180}_{173}Tl + ^{0}_{0}\gamma.

Explanation:

A nuclear reaction in which a heavy particle splits into another particle along with release of energy is called a nuclear fission reaction.

For example, ^{180}_{173}Tl \rightarrow ^{180}_{173}Tl + ^{0}_{0}\gamma

Here, energy is radiated in the form of gamma radiation.

Thus, we can conclude that the nuclear equation is ^{180}_{173}Tl \rightarrow ^{180}_{173}Tl + ^{0}_{0}\gamma.

The half life of Po-218 is three minutes. How much of a 200 atom sample will remain after 15 minutes
MakcuM [25]
<h3>Answer:</h3>

6.25 atoms

<h3>Explanation:</h3>

<u>We are given</u>;

  • The half life of Po-218 is 3 minutes
  • Initial sample is 200 atom
  • Time of decay is 15 minutes

We are required to calculate the remaining mass after decay;

Half life refers to the time taken for original amount of a radioactive sample to decay to a half.

To calculate the remaining mass we use the formula;

N = N₀ × 0.5^n where n is the number of half lives, N is the new amount and N₀ is the original amount.

n = 15 min ÷ 3 min

  = 5

Therefore;

New amount = 200 atom × 0.5^5

                      = 6.25 atoms

Therefore; the amount of the sample that will remain after 15 minutes is 6.25 atoms.
