Answer:

The gas will occupy a volume of 1.702 liters.

Explanation:

Let suppose that the gas behaves ideally. The equation of state for ideal gas is:

[tex]P\cdot V = n\cdot R_{u}\cdot T[/tex] (1)

Where:

[tex]P[/tex] - Pressure, measured in kilopascals.

[tex]V[/tex] - Volume, measured in liters.

[tex]n[/tex] - Molar quantity, measured in moles.

[tex]T[/tex] - Temperature, measured in Kelvin.

[tex]R_{u}[/tex] - Ideal gas constant, measured in kilopascal-liters per mole-Kelvin.

We can simplify the equation by constructing the following relationship:

[tex]\frac{P_{1}\cdot V_{1}}{T_{1}} = \frac{P_{2}\cdot V_{2}}{T_{2}}[/tex] (2)

Where:

[tex]P_{1}[/tex], [tex]P_{2}[/tex] - Initial and final pressure, measured in kilopascals.

[tex]V_{1}[/tex], [tex]V_{2}[/tex] - Initial and final volume, measured in liters.

[tex]T_{1}[/tex], [tex]T_{2}[/tex] - Initial and final temperature, measured in Kelvin.

If we know that [tex]P_{1} = 121\,kPa[/tex], [tex]P_{2} = 202\,kPa[/tex], [tex]V_{1} = 2.7\,L[/tex], [tex]T_{1} = 288\,K[/tex] and [tex]T_{2} = 303\,K[/tex], the final volume of the gas is:

[tex]V_{2} = \left(\frac{T_{2}}{T_{1}} \right)\cdot \left(\frac{P_{1}}{P_{2}} \right)\cdot V_{1}[/tex]

[tex]V_{2} = 1.702\,L[/tex]

The gas will occupy a volume of 1.702 liters.

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

Answer: It takes more energy to break the bonds of the reactants than is released when the  bonds in the products are formed

Explanation:

Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat. Thus it takes more energy to break the bonds of the reactants than is released when the  bonds in the products are formed

Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat. Thus More energy is released when the bonds in the products are formed than is used to  break the bonds in the reactants

Answer:

I think that would be true. The faster the wind, the longer it blows, or the farther it can blow uninterrupted, the bigger the waves. Therefore, a wave's size depends on wind speed, wind duration, and the area over which the wind is blowing

Answer: True.

Explanation: Yes, waves get energy from the wind through friction, so you see those waves get bigger each time. The longer the winds blows, the more friction, and energy it's getting, meaning better, and deadly waves. The wind can sometimes cause tsunamis if the its blowing too hard.

Explanation:

Formula when magnesium reacts with hydrochloric acid is given by;

Mg(s) + 2HCl(aq) = MgCl2(aq) + H2(g)

So, from the equation, we can see that the gas formed is hydrogen.

This hydrogen gas is collected by a method known as water displacement.

This gas can be tested for by holding a burning splint near to the top of the test container. The resulting effect should be a high pitched pop sound because the hydrogen gas will react with the oxygen gas in the air to result in a small explosion.
