Answer:

Group 7A

Explanation:

The group 7A elements consists of the most reactive non-metals on the periodic table.

This group is known as the group of halogens. They consist of element fluorine, chlorine, bromine, iodine and astatine.

The elements in this group have the highest electronegativity values.
They have 7 valence electrons and requires just one electron to complete their octets.
This way, they are highly reactive in their search for that single electron.

The density of a substance is 17.5 g/mL. Determine the volume (in mL) of 63.6 g of this substance.

andreyandreev [35.5K]

Answer:

<h2>volume = 3.63 mL</h2>

Explanation:

The density of a substance can be found by using the formula

<h3> $Density = \frac{mass}{volume}$ </h3>

Since we are finding the volume

Making volume the subject we have

<h3> $volume = \frac{mass}{Density}$ </h3>

From the question

mass = 63.6 g

Density = 17.5 g/mL

Substitute the values into the above formula and solve for the volume

That's

<h3> $volume = \frac{63.6}{17.5}$ </h3>

We have the final answer as

<h3>volume = 3.63 mL</h3>

Hope this helps you

xidation in redox reactions involves a. a loss of electrons and an increase in the oxidation number b. a gain of electrons and a

Strike441 [17]

Answer:

Option a is the right one

Explanation:

Redox reactions are defined as the reactions where one element is oxidized (so the oxidation state is increased); and another element is reduced (oxidation state decreases). These changes in the oxidations states are defined by a transference of electrons.

When the oxidation state decrease → reduction → the element gains electrons

When the oxidation state increase → oxidation → the element release electrons
