Akimi4 [234]3 years ago
5 0

Answer: (3) hydrogen ions as the only positive ions in solution

Explanation: Arrhenius acids are substances which dissociate in water to give H^+ ions.

For example: HCl is an Arrhenius acid.

HCl\rightarrow H^++Cl^-

Arrhenius bases are substances which dissociate in water to give OH^- ions.

For example: NaOH is an Arrhenius base.

NaOH\rightarrow Na^++OH^-

The answer is (3) hydrogen ions as the only positive ions in solution. One ionic compound must have positive ion and negative ion at the same time. The Arrhenius base has hydroxyl ion as only negative ions in solution.

How many moles of carbon atoms are present in a piece f diamond?
NNADVOKAT [17]
Diamond is an allotrope of carbon; that just means it is a different crystalline structure, but pure diamond contains only carbon atoms. (unrelated, but interesting - colored diamonds come from impurities like boron and nitrogen in the crystal structure!) The molar mass of carbon is 12.01 g/mol. You can find the molar mass by looking at the periodic table. If you look under number 6, Carbon, you should see the atomic weight right under it: 12.01. The molar mass is this same number, in grams. That means that one mole, or 6.022E23 carbon atoms, weigh 12.01 grams. 
<span>But you don't have one mole. You only have 2 grams. </span>
<span>So how many moles do you have? 2 grams out of 12 grams. 2/12 = 1/6 or 0.167. You have 1/6th of a mole. One mole is 6.022E23 atoms, but you only have 1/6th of that. I hope that thinking about it stepwise like this makes sense to you. It works the same for other atoms and molecules too. In a molecule, you would just add up the molar mass of all the component atoms. I hope this helps.

Electromagnetic wave travels faster through air than metal.

Option A

<u>Explanation:</u>

There are different kinds of wave energy. The most significant are electromagnetic and mechanical waves. The mechanical waves propagate through the medium by transfer of energy by vibrating of particles in medium.

So, the more number of particles present in the medium, the more fast the mechanical wave can propagate. So the mechanical waves travel faster in metals consisting of more number of free charge carriers. But electromagnetic waves does not need any of the medium to propagate. So it can travel faster in air than in metals.
