Select the correct answer. Thomas has 235 grams of K2S in the chemistry lab. How many atoms of potassium (K) are in 235 grams of
Readme [11.4K]

Atoms are the smallest division of the element. The potassium atoms present in the 235 gm of the compound is 2.57 \times 10^{24} atoms.

<h3>What is the number of atoms?</h3>

Given,

  • Mass (m) of Potassium sulfide (\rm K_{2}S) = 235 gm
  • Molar mass (M) of  Potassium sulfide = 110.26 g/mol

Calculate the number of moles as:

\begin{aligned}\rm Moles (n) &= \dfrac{\rm mass}{\rm molar\;\rm mass}\\\\&= \dfrac{235}{110.26}\\\\&=2.13\;\rm mol\end{aligned}

In the given compound \rm K_{2}S, there are two atoms of potassium and one atom of sulphur.

If, 1 mole = 2 \times 6.022 \times 10^{23} atoms of potassium

Then, 2.13 moles = X atoms

Solving for X:

2.13 \times 2 \times 6.022 \times 10^{23} = 2.57 \times 10^{24}

Therefore, option c. 2.57 \times 10^{24} is correct.

What are the potential problems for nearby water sources when using nuclear energy? Check all that apply.
Usimov [2.4K]

The energy discharged at the time of nuclear fusion or fission, mainly when used to produce electricity is known as nuclear energy. Although nuclear energy has become one of the most potent sources of energy in the present time, it also brings some harmful effects along with it, mainly by affecting the surrounding environment like the water bodies present nearby.  

Some of the potential problems for the nearby water sources when using nuclear energy are:  

1. It contaminates water with radioactive waste.  

2. It creates hazardous conditions for the species living in the water.  

3. It adds very hot water to cool water environments.  

4. It utilizes a resource, which becomes scarce at the time of drought.
