What is the pressure, in atm, of 24.5 L of ideal gas at 247.8 K if there are 1.8 moles present?

Answer:

it is from the currents the movements cause

Explanation:

Answer:The greater the difference in pressure, the faster the winds. When a high- and a low-pressure air mass are far apart, air moves slowly from high to low pressure.  When a high- and a low-pressure air mass are far apart, air moves quickly from high to low pressure.

Explanation:

Answer:

43.3 L

Explanation:

Applying,

V/T = V'/T'................... Equation 1

Where V = Initial volume of the ball0on, T = Initial temperature of the balloon, V' = Final volume of the balloon, T' = Final Temperature of the balloon.

make V' the subject of the equation

V' = VT'/T................ Equation 2

From the question,

Given: V = 47 L, T = 320 K, T' = 295 K

Substitute these values into equation 2

V' = (47×295)/320

V' = 43.3 L

The correct question is as follows: 0.500 moles of potassium oxide is dissolved in enough water to make 2.00 L of solution. Calculate the molarity of this solution (plz help!)

Answer: The molarity of this solution is 0.25 M.

Explanation:

Molarity is the number of moles of a substance divided by volume in liter.

As it is given that there are 0.5 moles of potassium oxide in 2.00 L of water so, the molarity of this solution is calculated as follows.

[tex]Molarity = \frac{moles}{volume(in L)}\\= \frac{0.5 moles}{2.00 L}\\= 0.25 M[/tex]

Thus, we can conclude that molarity of this solution is 0.25 M.

In the symbolic equation, chemical formulas are used instead of chemical names for reactants and products, while symbols are used to indicate the phase of each substance. It should be apparent that the chemical shorthand method is the quickest and clearest method for writing chemical equations.

Answer:

Explanation:

This is an example of a limiting reactant question, and is very common as a general chemistry problem.

We first see the balanced equation, that is:

2CuCl2+4KI→2CuI+4KCl+I2

We first need to find the limiting reactant

We see that 0.56 g of copper(II) chloride (CuCl2) reacts with 0.64 g of potassium iodide (KI) . So, let's convert those amounts into moles.

Copper(II) chloride has a molar mass of

134.45 g/mol . So in 0.56 g of copper(II) chloride, then there exist

0.56g134.45g/mol≈4.17⋅10−3 mol

Potassium iodide has a molar mass of

166 g/mol . So, in 0.64 g of potassium iodide, there exist

They made this graphics, how they measured the gas and how this affected the climate change horribly.

They created these images to show how the gas was measured and how the climate change was adversely affected the greenhouse gases.

A greenhouse gas is a gas that produces the greenhouse effect by both absorbing and emitting radiant energy at thermal infrared wavelengths. The five main greenhouse gases in the atmosphere of Earth are ozone, carbon dioxide, methane, and water vapor.

The gases that trap heat in the earth's atmosphere are referred to as greenhouse gases. The earth's surface warms during the day when the light beams through the atmosphere.

The earth's surface cools at night, redistributing heat into the atmosphere. However, part of the heat is captured by the atmosphere's greenhouse gases.

Therefore, how the climate change was adversely impacted the greenhouse gases must ask the team.

Answer:

2C₄H₁₀(g) + 13O₂(g) —> 8CO₂(g) + 10H₂O(g)

Explanation:

The balanced equation for the reaction between butane and oxygen to produce carbon dioxide and water can be written as follow:

C₄H₁₀ + O₂ —> CO₂ + H₂O

Next, we shall balanced the equation. This is illustrated below:

C₄H₁₀ + O₂ —> CO₂ + H₂O

There are 4 atoms of C on the left side and 1 atom on the right side. It can be balance by writing 4 before CO₂ as shown below:

C₄H₁₀ + O₂ —> 4CO₂ + H₂O

There are 10 atoms of H on the left side and 2 atoms on the right side. It can be balance by writing 5 before H₂O as shown below:

C₄H₁₀ + O₂ —> 4CO₂ + 5H₂O

There are 2 atoms of O on the left side and a total of 13 atoms on the right side. It can be balance by writing 13/2 before O₂ as shown below:

C₄H₁₀ + 13/2O₂ —> 4CO₂ + 5H₂O

Multiply through by 2 to express in whole number ratio.

2C₄H₁₀(g) + 13O₂(g) —> 8CO₂(g) + 10H₂O(g)

Thus, the equation is balanced.

The bowling ball has more kinetic energy than the tennis ball

Explanation:

Using the formula 1/2 mass × acceleration we found that the tennis ball had a kinetic energy of 0.75 while the bowling ball had a kinetic energy of 10.5 hence the bowling ball has the ability to do more work

The bowling ball has more kinetic energy than the tennis ball.

Given the following data:

Mathematically, kinetic energy is given by this formula:

[tex]K.E = \frac{1}{2} MV^2[/tex]

Where:

For tennis ball:

[tex]K.E = \frac{1}{2} \times 0.5 \times 3^2\\\\K.E = \frac{1}{2} \times 0.5 \times 9[/tex]

K.E = 2.25 Joules.

For bowling ball:

Answer: The amount of heat released when 233 grams of water at room temperature (25C) is frozen into ice at -15C is 17253.65 J.

Explanation:

As water converts into ice at [tex]0^{o}C[/tex]. So, the change in temperature is taking place from [tex]25^{o}C[/tex] to [tex]0^{o}C[/tex] and then from [tex]0^{o}C[/tex] to [tex]-15^{o}C[/tex].

So, amount of heat released by water is as follows.

[tex]q_{1} = m \times C \times (T_{2} - T_{1})\\= 233 g \times 4.18 J/g^{o}C \times (25 - 0)^{o}C\\= 24348.5 J[/tex]

m = mass of substance

C = specific heat of water = [tex]4.18 J/g^{o}C[/tex]

[tex]C'[/tex] = specific heat of ice = [tex]2.03 J/g^{o}C[/tex]

The amount of heat released by ice is as follows.

[tex]q_{2} = m \times C' \times (T'_{2} - T'_{1})\\= 233 g \times 2.03 J/g^{o}C \times (-15 - 0)^{o}C\\= -7094.85[/tex]

Now, total heat released during this change is as follows.

[tex]\Delta H = q_{1} + q_{2}\\= 24348.5 J + (-7094.85) J\\= 17253.65 J[/tex]

Thus, we can conclude that heat released when 233 grams of water at room temperature (25C) is frozen into ice at -15C is 17253.65 J.

The nitrogen gas and the oxygen gas will both occupy 50 liters.

Let us recall form the kinetic theory of gases that a gas is in constant random motion. The gas does not have a specific volume but takes on the volume of the container since it will expand and fill the container.

The volume occupied by the two gases will be the same as the volume of the container. Hence, the nitrogen gas and the oxygen gas will both occupy 50 liters.

Grams of AlCl₃ ~ 80 grams (1 sig. fig.)

Explanation:

Write and balance given equation.

Coefficients should be in smallest whole number ratios. => called ‘The Standard Equation’ and is assumed to be at 0˚C & 1atm. pressure.

3NaOH + AlCl₃ => Al(OH)₃ + 3NaCI

Write below compound what’s given and what’s needed, i.e., to be calculated.

Rxn:              3NaOH     +    AlCl₃   =>    Al(OH)₃  +  3NaCI

Given:            ---------           (?g)             --------        100.0g

Rxn Moles:    3 moles       1 mole          1 mole        3 moles

Calc’d Moles: ---------      (? Moles)         --------     100.0g/58g∙molˉ¹

= 1.724 mol NaCl

Calculate moles AlCl₃ needed using mole ratios:

          (? moles AlCl₃/1 mole AlCl₃) = (1.724 moles NaCl/3 moles NaCl)

          => ? moles AlCl₃ = (1.724 moles NaCl x 1 mole AlCl₃) / (3 moles NaCl)  

         => ? moles AlCl₃ = (1.724 x 1 / 3) mole AlCl₃ = 0.575 mole AlCl₃ needed

Convert moles AlCl₃ needed to grams AlCl₃ needed:

        Grams AlCl₃ needed = calculated moles AlCl₃ x formula wt. AlCl₃

                                 = 0.575 mole AlCl₃ x 133.34 grams AlCl₃/mole AlCl₃

                                 = 76.6705 grams AlCl₃ needed (calculated answer)

A. For every mole of carbon dioxide consumed, one mole of water is consumed

Explanation:

The photosynthetic equation is given as follows:

6CO2 + 6H2O → C6H12O6 + 6O2

The coefficient in front of each reactant and product is used to represent the number of moles needed for each compound/element in the reaction.

Based on this, this means that 6 moles of CO2 (carbon dioxide) needs to react with 6 moles of H2O (water) to form the products.

In a simpler form, this also means that for every 1 mole of carbon dioxide (CO2) consumed, one (1) mole of water (H2O) is consumed.

Answer:

6.1 M

Explanation:

Step 1: Calculate the moles of HNO₃ in the initial solution

A student has 475 mL (0.475 L) of a 4.5 M HNO₃ (4.5 mol HNO₃/ L) solution.

0.475 L × 4.5 mol HNO₃/ L = 2.1 mol HNO₃

He leaves the top of the container open, so water will evaporate, but the moles of HNO₃ will remain the same.

Step 2: Calculate the final concentration of the solution

2.1 moles of HNO₃ are in 347 mL (0.347 L) of solution.

[HNO₃] = 2.1 mol / 0.347 L = 6.1 M
