The product participates in a side reaction.
Explanation:
The reason why percentage yield for a chemical reaction can be less than a 100% is due to the presence of competing side reactions. As often the case and basics for all chemical reactions, mass and matter must be conserved. But sometimes the yield can be lower due to other reactions that must be considered.
- A competing side reaction that can affect the yield of products during a chemical procedure is often one in which some of the products can react with some molecules present in the environment or some of the unused reactants when available.
- Sometimes, a product can be hygroscopic, deliquescent or probably effervescent. This will definitely alter the expected amount of product one desires in a reaction based on stoichiometry.

The sulfuric acid–catalyzed reaction of isopentyl alcohol with acetic acid to form isopentyl acetate is performed. This reaction does not proceed to completion. After the reaction is heated under reflux for an hour, the product mixture is washed with aqueous sodium bicarbonate solution, and the organic layer is thoroughly dried. A distillation of the organic layer is then performed. Given the boiling points listed below, select the compound that will distill first.Compound Boiling point, ℃acetic acid 118 isopentyl acetate 142 isopentyl alcohol 130 sulfuric acid water 290

The volume of 45.6g of silver if the density of silver is 10.5g/mL is 4.342 ml. The correct option is A.
What is Volume?
Volume is the space occupied by a three-dimensional object. The volume of any object can be calculated by dividing the mass by its density. It is a scalar quantity. It is the total weight is that object.
Silver is an element in the periodic table. It is non-metal, and it is used in making ornaments and in medicines. The volume of the solver is calculated, and the mass and density are given.
The mass of silver is given, 45.6g
The density of the element is 10.5g/mL
Putting the value in the equation
The density and the mass would be divided.
Volume = 45.6g / 10.5 = 4.342
Thus, the volume of silver is 4.342 ml. The correct option is A.

Explanation:
first you get moles of silver
n=m/M
hence you add no of moles to this equation
c=nv
v=n/c

Answer:
Yes, molarity changes according to temperature.
Explanation:
Molarity equals to moles over volume
which can be also said;
Molarity = moles of solute / liters of solution
Well, the volume or liters of the solution depends on temperature.
If the temperature is high then the volume will be higher where the molarity decreases.

What is psychology?
Psychology is defined as the scientific discipline that studies mental state and processes and behavior in human and other animals.
It can also be defined as the scientific study of mind and behavior.
Environment is defined as the sum total of all the living and non living elements and there effect that influences human life.
Thus, the statements is not correct concerning the relationship between attention and perception is that individuals can easily detect changes in the environment when they are absorbed in a task.
