Answer:

Physical Properties

Alkali metals are good conductors of heat and electricity while halogens are poor conductors of heat and electricity.

Only specific to Alkali metals: They are soft and can be cut by knife.

Chemical Properties

Alkali metals have 1 valence electron while halogens have 7 valence electrons.

Alkali metals react with non-metals to form ionic compounds while halogens react with non-metals to form covalent compounds.

You can also look at the trends ( melting/boiling point, reactivity) down their group.

what is the concentration (in %v/v)) of the following solutions? a. 25 mL of ethanol is diluted to a volume of 150 mL with water

fenix001 [56]

The symbol %v/v means percent by volume. Assuming there is no volume effects when these substances are mixed, we calculate as follows:

% v/v = (25 mL ethanol / 25 mL + 150 mL ) x 100
%v/v = 14.29 mL ethanol / mL solution

Hope this answers the question.

Draw the condensed structural formulas for all the possible haloalkane isomers that have four carbon atoms and a bromine.

meriva

Answer: The isomers are shown in the image below.

Explanation:

Isomers are defined as the chemical compounds having the same number and kinds of atoms but arrangement are different.

For the alkane having four carbon atoms and 1 bromine atom, the IUPAC name of the haloalkane is bromobutane

There are 4 possible isomers for the given haloalkane compound:

1-bromobutane
2-bromobutane
1-bromo-2-methylpropane
2-bromo-2-methylpropane

The isomers of the given organic compound is shown in the image below.
