Answer 1

Answer:

According to the Arrhenius theory a substance that yields hydrogen ions as the only ion in an aqueous solution is Acid.

What are acids?

Acids are those substances which are having pH range from 0 to 7.

According to the Arrhenius theory of acid and base, acids are those compounds which donate H⁺ ion or proton in the aqueous medium and bases are those substances which donate OH⁻ ion in the aqueous medium.

Example of Arrhenius acids are HCl, CH₃COOH, HNO₃, etc.

Hence, those substance which yields H⁺ ions is acids.

Answer 2

Answer: According to Arrhenius theory of acid and bases, an acid is a proton donor, while base donates hydroxyl ions. Further, acid and base reacts to form salt and water.
Consider following example.
HCl + H2O → Cl- + H3O+
here, HCl has donated a proton, hence it is an acid.
Now consider following reactionHCl + NaOH ↔ NaCl + H2O
in this reaction, HCl donates proton, hence it is acid. On other hand, NaOH donates hydroxyl ion (i.e. OH-), hence it is a base.

A sample of sulfur has a mass of 232 grams. How many moles of sulfur are in the sample?

Answers

Answer : The number of moles of sulfur present in sample are, 7.343 moles

Solution : Given,

Mass of sulfur = 232 gram

Molar mass of sulfur = 32 g/mole

Formula used :

$\text{Moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

$\text{Moles of Sulfur}=\frac{\text{Mass of Sulfur}}{\text{Molar mass of Sulfur}}=(232g)/(32g/mole)=7.343moles$

Therefore, the number of moles of sulfur present in sample are, 7.343 moles

Sulfur has a molar mass of 32.1 g/mole. So 232 g S / 32.1 g S = 7.22 moles

If an atom has an electron configuration of 2.8.2, what will it be most likely to bond with? A. One fluorine atom B. Two chlorine atoms C. None of these D. One arsenic atom

Answers

Answer:

B. Two chlorine atoms

Explanation:

This electronic configuration shows that the given atom is magnesium.

Electronic configuration of magnesium:

Mg¹² = 1s² 2s² 2p⁶ 3s²

There are two valance electrons of magnesium that's why it would react with two atoms of chlorine. Chlorine is present in seventeen group. It has seven valance electrons. It required just one electron to get complete octet. While magnesium needed to lose two electrons to get complete octet. That's why two chlorine atoms bonded with one magnesium atom. Thus both would get complete octet.

Mg + Cl₂ → MgCl₂
