Answer:
PH₃.
Explanation:
Hello.
In this case, among the options:
PH₃, GaF₃, SF₂ and CO₂
We compute their molar masses by adding the atomic masses of the constituting elements by their subscripts:
Thus, the answer is PH₃.
Best regards.

Answer:</h3>
Molarity is 0.046 M
<h3>
Explanation:</h3>
We are given;
1.72 mol of LiCl in 37.5 L of solution
We will take the question to be; calculate the molarity of LiCl
Therefore,
we can start by defining molarity as the concentration of a solution in moles per liter.
Molarity of a solution is calculated by dividing the number of moles of solute by the volume of solution.
Molarity = Moles of solute ÷ Volume of the solution
Thus, in this case;
Molarity of LiCl = Moles of LiCl ÷ Volume of the solution
= 1.72 moles ÷ 37.5 L
= 0.0459 M
= 0.046 M
Therefore, the molarity of LiCl solution is 0.046 M
Answer:
<h2>57,500 J</h2>
Explanation:
The potential energy of a body can be found by using the formula
PE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 10 m/s²
From the question we have
PE = 25 × 10 × 230 = 57,500
We have the final answer as
<h3>57,500 J</h3>
Hope this helps you
Answer:
precipitation means water droplets may grow as a result of additional condensation of water vapor when the particles collide. If enough collisions occur to produce a droplet with a fall velocity which exceeds the cloud updraft speed, then it will fall out of the cloud as precipitation.
