Answer:

4.03 g

Explanation:

The mass in grams of the hydrogen gas is 4.0 g

From the question,

We are to determine the mass in grams of the hydrogen gas.

First, we will determine the number of moles of hydrogen gas present.

Using the formula,

[tex]Number\ of\ moles =\frac{Number\ of \ molecules}{Avogadro's\ constant}[/tex]

From the given information,

Number of hydrogen molecules = 1.204 × 10²⁴ molecules

Thus,

Number of moles of hydrogen gas present = [tex]\frac{1.204 \times 10^{24} }{6.02 \times 10^{23} }[/tex]

Number of moles of hydrogen gas present = 2 moles

Now, for the mass of the hydrogen gas

Using the formula,

Mass = Number of moles × Molar mass

Molar mass of hydrogen gas = 2.016 g/mol

Then,

Mass of the hydrogen gas = 2 × 2.016

Mass of the hydrogen gas = 4.032 g

Mass of the hydrogen gas ≅ 4.0 g

Hence, the mass in grams of the hydrogen gas is 4.0 g

Explanation: Honestly, I just looked it up on Socratic.

Answer:

5a. 13.5 moles of F₂

5b. 3.33 moles of Ar.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

3F₂ + 2Ar —> 2ArF₃

From the balanced equation above,

3 moles of F₂ reacted with 2 moles of Ar to produce 2 moles of ArF₃.

5a. Determination of the number of mole of fluorine, F₂, needed to produce 9 moles of ArF₃.

From the balanced equation above,

3 moles of F₂ reacted to produce 2 moles of ArF₃.

Therefore, Xmol of F₂ will react to produce 9 moles of ArF₃ i.e

Xmol of F₂ = (3 × 9)/2

Xmol of F₂ = 13.5 moles

Thus, 13.5 moles of F₂ is needed.

5b. Determination of the number of mole of Ar needed to react with 5 moles F₂.

From the balanced equation above,

3 moles of F₂ reacted with 2 moles of Ar.

Therefore, 5 moles of F₂ will react with = (5 × 2)/3 = 3.33 moles of Ar.

Thus, 3.33 moles of Ar was consumed.

Answer:

Sodium chloride

Explanation:

There are several salts in seawater, but the most abundant is ordinary table salt or sodium chloride (NaCl). Sodium chloride, like other salts, dissolves in water into its ions, so this is really a question about which ions are present in the greatest concentration. Sodium chloride dissociates into Na+ and Cl- ions.

Answer:

A solution of potassium chloride when mixed with silver nitrate solution forms an insoluble white substance silver chloride.

Mg + 2HCl → MgCl2 + H2

4H2O → 4H^+ + 4OH^-

2Mg + O2 → 2MgO

Explanation:

This question has to do with the balancing of chemical reaction equations. The general rule for balancing chemical reaction equation is that the number of atoms of each element on the left hand side of the reaction equation must be equal to the number of atoms of the same element on the right hand side of the reaction equation.

This principle was followed in balancing each reaction equation above. For instance, in the burning of magnesium, there are two atoms of both magnesium and oxygen on either side of the reaction equation.
