Answer:
Explanation:
Hello!
In this case, since the heat of vaporization is related with the energy required by a substance to undergo the phase transition from liquid to gas, we can compute such amount of energy as shown below:
In such a way, since the enthalpy of vaporization is given as well as the mass, we compute the energy as shown below:
Best regards!
The products being more stable than the reactants is the factor which would reduce the yield of a reaction and is denoted as option B under standard conditions.
<h3>What is a Chemical reaction?</h3>
This is the process in which one or more substances which are referred to as reactants are converted into new substances which we call the products.
A chemical reaction involves atoms exhibiting different bond formation so as to ensure they acquire an octet configuration and promotes proper stability of the products.
When the products are more stable than the reactants it means it is unable to form other products thereby decreasing the yield which is why it was chosen as the most appropriate choice.

Here is your answer:
The amount of electrons that the element Beryllium has is: 4
Reason:
Beryllium atomic number is 4
Therefore the amount of protons and electrons Beryllium has is 4
Your answer is 5.
Hope this helps.
Each element absorbs light at specific wavelengths unique to that atom. When astronomers look at an object's spectrum, they can determine its composition based on these wavelengths. The most common method astronomers use to determine the composition of stars, planets, and other objects is spectroscopy.
hope this helps you! :-)
