Answer is ₂₀⁴²Ca.<span>

In AZX notation
   A<span> - Represents the </span>mass number of atom.
         Mass number = number of protons + number of neutrons.
<span>         It is shown at the </span>above of the left side<span> of the atom.</span>
<span>         Here it is </span>42. 

<span>  </span>Z - Represents the atomic number.<span>
       Atomic number = number of protons.
       </span><span>It is shown at the</span> bottom line of the left side of the atom.<span>
       </span>Here it is 20.<span>
 
  X - </span>Represents the symbol of the atom.<span>
     <span>   </span></span>Here</span> X is Ca.<span>

A solute added to a solvent raises the boiling point of the solution because: Select one: a. The solute particles raise the solv
loris [4]

Answer:

See the answer below

Explanation:

<em>The correct answer would be that the solute particles lower the solvent's vapor pressure, thus requiring a higher temperature to cause boiling.</em>

Dissolving a solute particle in a solvent leads to a decrease in the vapor pressure of the solvent above the resulting solution when compared to the pure solvent. The lower the vapor pressure of a liquid, the higher the temperature required for the liquid to boil and vice versa. Hence, a higher temperature would be needed to boil a solvent with dissolved solutes.

The amount of energy required to heat water for a 10-minute shower (50 gallons) is 2.2125 kJ. How many calories is this?
Zigmanuir [339]
From the problem statement, this is a conversion problem. We are asked to convert from units of kilojoules to units of calories. To do this, we need a conversion factor which would relate the different units involved. We either multiply or divide this certain value to the original measurement depending on what is asked. From literature, we will find that 1 kilojoule is equal to 239 calories. We do as follows:
<span>
2.2125 kJ ( 239 calories / 1 kJ ) = 528.79 calories
