Concept explainers
(a)
Interpretation:
The term matter has to be defined.
Concept Introduction:
Matter: Anything that has mass and volume.
(a)

Explanation of Solution
Definition for Matter: Anything that has mass and volume (which means it takes up space) is considered as matter.
Even though matter appear to be smooth and continous it is actually composed of a lot of tiny little pieces called atoms and molecules.
(b)
Interpretation:
The term mass has to be defined.
Concept Introduction:
Mass: the amount of matter an object contains, it is measured in gram, kilogram.
(b)

Explanation of Solution
Definition for mass: The amount of matter (Anything that has mass and volume) in an object It is measure in gram, kilogram.
Mass of object is independed of its location.
(c)
Interpretation:
The term weight has to be defined.
Concept Introduction:
Weight: It is a force of gravity acting on an object.
Mass is the amount of matter an object contains.
(c)

Explanation of Solution
Definition for weight: It is a force of attraction between the object and the earth’s gravity. The weight of an object can vary from place to place and changes with its location on the earth.
(d)
Interpretation:
The term substance has to be defined.
Concept Introduction:
Substance: It is a kind of matter that cannot be separated into other kinds of matter by any physical or chemical changes.
(d)

Explanation of Solution
Definition for Substance: It is a kind of matter that cannot be separated into other kinds of matter by any physical or chemical changes.
A pure substance is composed of two or more elements whose composition is constant.
(e)
Interpretation:
The term mixture has to be defined.
Concept Introduction:
Mixture: Two or more pure substances that are mixed together but not joined chemically.
A pure substance is composed of two or more elements whose composition is constant.
(e)

Explanation of Solution
Definition for mixture: Two or more pure substances that are mixed together but not joined chemically. They are impure substances.
Example: salt water, smog.

- Predict the major products of the following organic reaction: NC Δ ? Some important Notes: • Draw the major product, or products, of the reaction in the drawing area below. • If there aren't any products, because no reaction will take place, check the box below the drawing area instead. • Be sure to draw bonds carefully to show important geometric relationships between substituents. Note: if your answer contains a complicated ring structure, you must use one of the molecular fragment stamps (available in the menu at right) to enter the ring structure. You can add any substituents using the pencil tool in the usual way. Click and drag to start drawing a structure. Х аarrow_forwardPredict the major products of this organic reaction.

- Consider the following reactants: Br Would elimination take place at a significant rate between these reactants? Note for advanced students: by significant, we mean that the rate of elimination would be greater than the rate of competing substitution reactions. yes O no If you said elimination would take place, draw the major products in the upper drawing area. If you said elimination would take place, also draw the complete mechanism for one of the major products in the lower drawing area. If there is more than one major product, you may draw the mechanism that leads to any of them. Major Products:arrow_forwardDraw one product of an elimination reaction between the molecules below.
