We assume that the volume of the molecules themselves in a gas sample is negligible compared to the bulk volume of the gas sample: this helps us to explain why gases are so compressible.
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.

Sometimes it can be true, but if you think of it another way: the warmer the water is, the quicker the substance dissolves in that...
Meaning you have to give heat to the system (ex. tea) in order to get e.g. the sugar dissolved :) However, in extreme cases heat can also be released!
Answer:
The neutral organic product is Imine.
Explanation:
From the image attached below, we will see an organic compound the question intended us to work out.
The proposed reaction is between cyclohexane and a stick structure of butylamine to yield imine as the product. The stepwise process and the mechanism carried out to get the product of this reaction is also shown in the image attached below.
They originated from cetral asia, but the americans brought them over.
