Typically, the actual yield is lower than the theoretical yield because few reactions complete (i.e., are not 100% efficient) or because not all of the product in a reaction is collected. It is also conceivable for the real yield to exceed the theoretical yield.

What is theoretical yield ?

Theoretical yield is what would be obtained if 100% of the reaction was completed and no product was wasted in any way; however, procedures are not this efficient. Everything is dependent on the experimenter's precision and the reaction. Some reactions are reversible, meaning that less than 100% of the reaction proceeds to completion; some reactions do not go to completion because they require a large amount of energy or additional time, for example. Substances in the reaction may be lost throughout the method or difficult to separate from other sections of the experiment. In chemistry, some degree of inaccuracy is always expected.

What is the daughter nucleus produced when Au195 undergoes electron capture?
VashaNatasha [74]

Pt195 having 78 atomic number is the daughter nucleus produced when Au195 undergoes electron capture.

An unstable isotopes can undergoes radioactive decay to form a more stable isotopes . Initial isotopes is called parent nuclide and the resultant isotopes from radioactive decay is called the daughter nuclide There are several radioactive decay like alpha decay , beta decay  , gamma decay , electron capture etc .

In electron capture , the atom have only one less which is daughter isotopes than electron than atomic number of parent isotopes.

Can someone please explain me the difference between physical changes and physical properties and of chemical changes and chemic
morpeh [17]

Answer:

Explanation:

Physical properties and physical change:

Physical properties are the properties of substance that do not involve the change in to another matter while the process through which change is happen is called physical change.

For example,

Melting point is physical property and the process "melting" is called physical change.

Freezing point is physical property and the process "freezing" is called physical change.

Chemical property and chemical change:

Chemical property is the ability of substance to change into another substance while the process through through which it is happen is called chemical change or chemical reaction.

For example:

The chemical property of iron is to react with oxygen and form rust. This process or chemical change is called corrosion. So corrosion is chemical change.

Hydrocarbon react with oxygen and form water and carbon dioxide. It is the chemical property. While the process is called combustion so combustion is a chemical change.

Rank the following substances/solutions in order of lowest boiling point to highest boiling point where 1 has the lowest boiling
poizon [28]

Answer:

1) pure water

2) 0.75 m CaCl2

3) 1.0 m NaCl

4) 0.5 m KBr

5) 1.5 m glucose (C6H12O6)

Explanation:

Boiling point elevation is a colligative property. Coligative properties are properties that depend on the amount of solute present in the system. The boiling point of solvents increase due to the presence of solutes.

The boiling point elevation depends on the number of particles the solute forms in solution and the molality of the solute. The more the number of particles formed by the solute and the greater the molality of the solute, the greater the magnitude of boiling point elevation.

The order of decreasing hoping point elevation is;

1) 0.75 m CaCl2

2) 1.0 m NaCl

3) 0.5 m KBr

4) 1.5 m glucose (C6H12O6)

What is the proper solution to the following equation? Answer with correct significant figures. (23.1 + 5.61 + 1.008) × 7.6134 ×
OleMash [197]

(23.1 + 5.61 + 1.008) × 7.6134 × 8.431  

= 29.718 × 7.6134 × 8.431

=1907.55608

The equation is solved in the manner that the term in the bracket is added first then mutiplication is done as according to Bodmas rule, if an equation contains brackets that need to be solved first then other operation that is  division,multiplication, addition and subtraction are performed from left to right .
