Explanation:

The kinetic energy of a gas molecule is given by :

$E=\dfrac{3}{2}kT\\\\\implies E\propto T$

It means, whenever the temperature of gas is increased, its kinetic energy will increase and the space between the particles gets increase. So, the space in which particles can collide with each other increases i.e. its volume gets high.

Hence, the correct option is (A). "higher temperature more kinetic energy → more space between particles – higher volume".

The type of central-atom orbital hybridization corresponds to each electron-group arrangement

Linear

What is linear arrangement?

Linear molecules are molecules that are straight and have a bond angle of 180 degrees. These molecules are made up of a central atom that is bonded to two other atoms via single or double bonds (sometimes there can be triple bonds as well).

Furthermore, the central atom usually can have either 0 or 3 lone electron pairs (AX2 or AX2E3) in the AXE notation.

The geometry described by linear molecular geometry revolves around a central atom that is bonded to two other atoms (or ligands) at a bond angle of 180°.

The most reactive metals are located at the a)top b)far-left c)far-right d)center of the periodic table.

Jlenok [28]

Answer:

Bottom left corner of the periodic table

Explanation:

The elements toward the bottom left corner of the periodic table are the metals that are the most active in the sense of being the most reactive. Lithium, sodium, and potassium all react with water, for example.

Gnom [1K]

Answer:

1.1 × 10²⁴ atoms Mg

General Formulas and Concepts:

Atomic Structure

Moles
Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.

Stoichiometry

Using Dimensional Analysis

Explanation:

Step 1: Define

Identify

[Given] 1.8 mol Mg

[Solve] atoms Mg

Step 2: Identify Conversions

Avogadro's Number

Step 3: Convert

[DA] Set up: $\displaystyle 1.8 \ mol \ Mg(\frac{6.022 \cdot 10^{23} \ atoms \ Mg}{1 \ mol \ Mg})$
[DA] Multiply [Cancel out units]: $\displaystyle 1.08396 \cdot 10^{24} \ atoms \ Mg$

Step 4: Check

Follow sig fig rules and round. We are given 2 sig figs.

1.08396 × 10²⁴ atoms Mg ≈ 1.1 × 10²⁴ atoms Mg

Explanation:

I mean they say all those things , but if it has to do with just the device I'm guessing it'd most likely be They can sense the presence of spiritual energy since they claim it's the device they are using to tell them if there is something there they can't see.

True or False. It is reasonable to assume that an atom with a positive oxidation number could make a chemical bond with an atom

patriot [66]

A loss of negatively-charged electrons corresponds to an increase in oxidation number, while a gain of electrons corresponds to a decrease in oxidation number. Therefore, the element or ion that is oxidized undergoes an increase in oxidation number.

Hope this helped
