<span>Beryllium
This is because it is in a group where Alkaline earth metals are but does not exhibit true properties of elements in that group as It exhibits amphoteric properties showing both the properties of a base and that of an acid.</span>
It would be challenging to calculate the percentage of simply acetic acid in vinegar if other acids were also present since they would mix with it.
<h3>Describe acid.</h3>
A chemical that creates salts when it combines with specific metals while also releasing hydrogen atoms into water. Acids have a sour taste and give some colors, a reddish tint. Acids generated by the body, such stomach acid, can assist organ function. One type of acid is hydrochloric acid.
<h3>Where does acid come from?</h3>
For instance, they can be used as an essential component in the chemical industry, like an electrolyte in a wet-cell battery (like a car battery), and to remove rust from metals.

Answer:
The maximum number of moles of PH₃ that can be formed is 0.8 moles.
Explanation:
The balanced reaction is:
P₄ + 6 H₂ → 4 PH₃
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:
- P₄: 1 mole
- H₂: 6 moles
- PH₃: 4 moles
The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.
To determine the limiting reagent, you can use a simple rule of three as follows: If by stoichiometry of the reaction 6 moles of hydrogen react with 1 mole of phosphorus, 4 moles of hydrogen will react with how many moles of phosphorus?
moles of phosphorus= 0.667
But 0.667 moles of phosphorus are not available, 0.2 moles are available. Since you have less moles than you need to react with 4 moles of hydrogen, phosphorus will be the limiting reagent.
Then you can apply the following rule of three: if by stoichiometry 1 mole of P₄ forms 4 moles of PH₃, 0.2 moles of P₄ will form how many moles of PH₃?
moles of PH₃= 0.8
<u><em>The maximum number of moles of PH₃ that can be formed is 0.8 moles.
