Answer:

2.) When waves hit the shoreline, they transfer their energy to the land.

3.) Wind transfers its energy to the water to create ocean waves.

Explanation:

I got it right on the test.

Wind transfers its energy to the water of the ocean to produce waves and this waves transfers its energy to the land.

Transfer of energy means the relocation of energy from one system to another or from one form to other.

When wind flows over the surface of the ocean, then they transfer their energy to water of the ocean. This absorbed energy by the water of ocean is seen in the form of the ocean waves or also known as wave energy.

Now the vertical motion of this waves on the surface of the ocean due to the presence of the kinetic energy, transfers its energy to the sea shoreline and results in the displacement of the sand or land.

Hence, option (2) & (3) is correct i.e. wind transfers its energy to the water and waves transfers its energy to the land.

Explanation:

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: There are 113 moles of O in 12.6 moles of [tex]Fe(NO_3)_3[/tex]

Explanation:

Given : moles of [tex]Fe(NO_3)_3[/tex] = 113.4

To find : moles of O = ?

1 mole of [tex]Fe(NO_3)_3[/tex] contains = 9 moles of O atoms

Thus 12.6 mole of [tex]Fe(NO_3)_3[/tex] contains = [tex]\frac{9}{1}\times 12.6=113.4[/tex] moles of O atoms

Thus there are 113 moles of O in 12.6 moles of [tex]Fe(NO_3)_3[/tex]

Answer:

3.79 moles

Explanation:

To convert moles to gams of a substance we need to find the molar mass of the substance. For Ca(OH)₂ th molar mass is:

1Ca = 40.08g/mol

2O = 2*16g/mol = 32g/mol

2H = 2*1.01g/mol = 2.02g/mol

The molar mass is:

40.08g/mol + 32g/mol + 2.02g/mol = 74.1g/mol

And moles are:

281g * (1mol / 74.1g) =

Answer:

60 Liters

Explanation:

The equation for this reaction is given as;

N2 + 3H2 → 2NH3  

From the reaction;

3 mol of H2 produces 2 mol of NH3

At STP;

1 mol = 22.4 L

This means

67.2 L ( 3 * 22.4) of H2 produces 44.8 L ( 2 * 22.4) of NH3

How many L of H2 would produce 40 L of NH3

67.2 = 44.8

x = 40

Solving for x;

x = 40 * 67.2 / 44.8

x = 60 L

Answer:

Pretty sure it's true.

On Earth, we only see part of the moon that is illuminated or not, since it revolves around the Earth. However, the sun is stationary and doesn't move, meaning that one side of the moon is always lit by the sun as it revolves around the Earth.
