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.

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.

Answer:

P2 = 4.76 atm

Explanation:

Given:

T1 = 235K. P1 = 3.80 atm

T2 = 298K. P2 = ?

Here, we use Gay-Lussac's law:

P1/T1 = P2/T2

Solving for P2, we get

P2 = (T2/T1)P1

= (298K/238K)(3.80 atm)

= 4.76 atm

Answer:

If a solid is added to a liquid until no more of the solid will dissolve saturated solution is formed.

According to the concept of solubility, if a solid is added to a liquid until no more of the solid will dissolve saturated solution is formed.

Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.

The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

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

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.

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

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:

[tex]K.E = \frac{1}{2} \times 7 \times 2^2\\\\K.E =3.5 \times 4[/tex]

K.E = 14 Joules.

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.
