Explanation:
If I have 0.070 moles of gas at a pressure of 0.20 atm and at a temperature of 8.00°C,
what is the volume of the container that the gas is in?
Answer:
PV=nRT
0.20×v = 0.070×8.00
0.20V= 0.56
0.20v÷0.20v = 0.56÷0.20v
= 2.8

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:
It won't be good.
Explanation:
In the core of the sun, hydrogen is produced by nuclear fusion. when the sun ages, it starts to run out of the hydrogen. when it runs out, nuclear fusion can't generate heat, and then the sun expands, becoming a red giant.

what is the proper formulanGaseous Butane (C4H10) that reacts with Gaseous Oxygen (O2) in a combustion reaction to form Carbon dioxide Gas and Gaseous Water (Dihydrogen monoxide).
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.

At the Sprite bottling plant where the temperature is at 235K, each bottle can hold 3.80 atm of pressurized carbon dioxide gas (to make the soda fizzy). At room temperature 298K what is the new pressure?
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

What is a yield. in your own words but be more detailed about what you say.
Answer:
Yield is the income on an investment over a period of time. It is calculated by taking interest or dividends earned by the investment, then dividing them by the value of the investment. It's usually expressed as an annual percentage, and excludes capital gain, which are the profits earned from buying something at one price and selling it at a higher price.

Answer:
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.
What is 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.

A student has 475 mL of a 4.5 M HNO3 solution. He leaves the top of the container Monday morning the volume of solution is now 347 mL. What is the conventtration of the solution now
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

In a symbolic equation, chemical names are used for reactants and product. True or false
Answer
false
Explanation:

This is a false statement!
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.

an evacuated cylinder has a volume of 50 liters. if 20 liters of nitrogen fas and 20 liters of oxygen gas are pumped into this evacuated cylinder, how much of the cylinder is filled with the two gasses?
The nitrogen gas and the oxygen gas will both occupy 50 liters.
Volume of a gasLet 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.

0.500 mile of potassium oxide is dissolved in enough water to make 2.00 L of solution. Calculate the molarity of this solution (plz help!) plz no links
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.

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