True or False: Ionic bonding means atoms COMPLETELY GIVE AWAY OR TAKE their electrons from each other. *

ziro4ka [17]

Answer: The given statement is True.

Explanation:

An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element and the element which accepts the electrons is known as electronegative element. This bond is formed between a metal and an non-metal.

A covalent bond is formed when an element shares its valence electron with another element. This bond is formed between two non metals.

Thus the given statement is True.

Maslowich

Answer:

Solids

Explanation:

At standard room temperature and pressure, most of the elements are solids.

Just a few of the elements are liquids and gases at this temperature.

The periodic table is made up of metals, metalloids and non-metals. Most of these substances are actually solid.

Some non-metals are gaseous at standard room temperature.

A gas occupies a volume of 60 L at a temperature of 0.5 K. What will the volume be at 4 K?

Flauer [41]

Answer:

480 L

Explanation:

In order to solve this question, you should be familiar with gas laws. (I will attach a picture showing all of them under my answer.) In this question in particular, however, we only need Charles's Law because we're dealing with temperature and volume.

As we can see, Charles's Law is:

$\frac{V_{1} }{T_{1} } = \frac{V_{2} }{T_{2} }$

or, initial volume over initial temperature equals final volume over final temperature.

In this question, 60 L is our initial volume, and 0.5 K is our initial temperature (K being Kelvin). We are only given 4 K as our final temperature. We are asked to solve for the final volume. Let's set up the equation and solve for $V_{2}$ :

--------------------------------------------------------------------------------------------------------------

(60) / (0.5) = $V_{2}$ / (4)

↓

120 = $V_{2}$ / 4

×4 ×4

↓

$V_{2}$ = 480 L

--------------------------------------------------------------------------------------------------------------

There's our answer! Feel free to comment if you have any questions about my answer :)
