<h3>Answer </h3>

Option C= It must generate hydroxide ions in water

<h3>Explanation </h3>

An Arrhenius base is a substance that, when dissolved in an aqueous solution, increases the concentration of hydroxide, or OH-, ions in the solution. An aqueous solution is a solution that has water present in it.

<h3>Example </h3>

A base, sodium hydroxide, is added to an aqueous solution.  It dissociates into sodium, Na+, and hydroxide, OH-, ions. Because the hydroxide ions are released in the aqueous solution, the hydroxide concentration increases; therefore, NaOH is an Arrhenius base.

<h3>Chemical equation </h3>

NaOH (s)  → Na+ (aq) + OH– (aq)

Jet001 [13]

Two blocks of platinum have a temperature of 200 Celsius. Both the blocks have the same amount of thermal energy because both are metals which conducts heat energy throughout their bodies.

<h3>What is conduction?</h3>

Conduction is the process by which heat energy is transmitted between neighboring atoms or molecules. We know that metals are the good conductors of heat and electricity so if one part absorb heat, it will spread to the whole body so we can conclude that the thermal energy will remain the same amount throughout the whole body.

How to convert moles 3.612 x 10^23 atoms Fe
Finger [1]

Answer:

0.6 moles of Fe

Explanation:

Given data:

Number of atoms of Fe = 3.612×10²³

Number of moles = ?

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

For example,

1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen

From atoms to mole:

3.612×10²³ atoms of Fe × 1 mole /  6.022 × 10²³ atoms

0.6 moles of Fe
