Which of the following are the same and which are different?
a. a substance and a pure substance
b. a heterogeneous mixture and a solution
c. a substance and a mixture
d. a homogeneous mixture and a solution
(a)
Interpretation:
A substance and a pure substance is different or same.
Concept introduction:
There are different substances present in the universe. On the basis of their composition, they can be described as pure and impure substances.
Answer to Problem 60A
A substance and a pure substance are same.
Explanation of Solution
The substances are the material present in the environment, which have a set of elements and they have a different proportion. It can be made up of single type of atoms or different types of atoms in a definite proportion. The substances are pure, hence, pure substance and substance is same.
(b)
Interpretation:
A heterogenous mixture and a solution is different or same.
Concept introduction:
The mixture can be defined as a physically combined material made up of two or more different substances.
Answer to Problem 60A
A heterogenous mixture and a solution are different.
Explanation of Solution
The mixture can be of two types, heterogenous or homogenous. Heterogenous mixture is when the substances present in the mixture have different phases and the homogenous mixture is when the all the substances are present in the same phase. The solution is present in same phase and evenly distributed, hence, it is homogenous.
(c)
Interpretation:
A mixture and a substance is different or same.
Concept introduction:
The mixture can be defined as a physically combined material made up of two or more different substances. There are different substances present in the universe. On the basis of their composition, they can be described as pure and impure substances.
Answer to Problem 60A
A mixture and a substance are different.
Explanation of Solution
The substances are the material present in the environment, which have a set of elements and they have a different proportion. The mixture is a combination of two or more substances, hence, they are not same.
(d)
Interpretation:
A homogenous mixture and a solution is different or same.
Concept introduction:
The mixture can be defined as a physically combined material made up of two or more different substances.
Answer to Problem 60A
A homogenous mixture and a solution are same.
Explanation of Solution
The mixture can be of two types, heterogenous or homogenous. Heterogenous mixture is when the substances present in the mixture have different phases and the homogenous mixture is when the all the substances are present in the same phase. The solution is present in same phase and evenly distributed, hence, it is homogenous in nature, so, both are same.

That is, select '1' next to the reaction that will have the fastest initial rate, select '2' next to the reaction that will have the next fastest initial rate, and so on. If two reactions will have very similar initial rates, you can select the same number next to both. If a reaction will have zero or nearly zero initial rate, don't select a number and check the box in the table instead. Note: the "Nu" in these reactions means "a generic nucleophile." ملی CI :Nu 2 он 3 H Reaction Relative Rate (Choose one) ▼ Nu :CI: zero or nearly zero Nu :Nu bi (Choose one) zero or nearly zero : Nu لی Nu :H (Choose one) zero or nearly zeroarrow_forward9:12 AM Tue Mar 4 66% Problem 38 of 15 Submit Curved arrows are used to illustrate the flow of electrons.
