Answer:
1) The new pressure of the gas is 500 kilopascals.
2) The final volume is 1.44 liters.
3) Volume will decrease by approximately 67 %.
4) The Boyle's Laws deals with pressures and volumes.
Explanation:
1) From the Equation of State for Ideal Gases we construct the following relationship:
[tex]\frac{P_{2}}{P_{1}} = \frac{V_{1}}{V_{2}}[/tex] (1)
Where:
[tex]P_{1}, P_{2}[/tex] - Initial and final pressure, measured in kPa.
[tex]V_{1}, V_{2}[/tex] - Initial and final pressure, measured in mililiters.
If we know that [tex]P_{1} = 100\,kPa[/tex], [tex]V_{1} = 500\,mL[/tex] and [tex]V_{2} = 1000\,mL[/tex], then the new pressure of the gas is:
[tex]P_{2} = P_{1}\cdot \left(\frac{V_{1}}{V_{2}} \right)[/tex]
[tex]P_{2} = 500\,kPa[/tex]
The new pressure of the gas is 500 kilopascals.
2) Let suppose that gas experiments an isothermal process. From the Equation of State for Ideal Gases we construct the following relationship:
[tex]\frac{P_{2}}{P_{1}} = \frac{V_{1}}{V_{2}}[/tex] (1)
Where:
[tex]P_{1}, P_{2}[/tex] - Initial and final pressure, measured in kPa.
[tex]V_{1}, V_{2}[/tex] - Initial and final pressure, measured in mililiters.
If we know that [tex]V_{1} = 3.60\,L[/tex], [tex]P_{1} = 10\,kPa[/tex] and [tex]P_{2} = 25\,kPa[/tex] then the new volume of the gas is:
[tex]V_{2} = V_{1}\cdot \left(\frac{P_{1}}{P_{2}} \right)[/tex]
[tex]V_{2} = 1.44\,L[/tex]
The final volume is 1.44 liters.
3) From the Equation of State for Ideal Gases we construct the following relationship:
[tex]\frac{P_{2}}{P_{1}} = \frac{V_{1}}{V_{2}}[/tex] (1)
Where:
[tex]P_{1}, P_{2}[/tex] - Initial and final pressure, measured in kPa.
[tex]V_{1}, V_{2}[/tex] - Initial and final pressure, measured in mililiters.
If we know that [tex]\frac{P_{2}}{P_{1}} = 3[/tex], then the volume ratio is:
[tex]\frac{V_{1}}{V_{2}} = 3[/tex]
[tex]\frac{V_{2}}{V_{1}} = \frac{1}{3}[/tex]
Volume will decrease by approximately 67 %.
4) The Boyle's Laws deals with pressures and volumes.

Which of these compounds has the largest percentage by mass of nitrogen? NO N2O NO2 N2O3
The largest mass percentage of nitrogen in NO. Therefore, option (A) is correct.
What is the mass percentage?The percentage by mass of an element in a chemical compound can be described as the number of parts by mass of the element contained in 100 parts by mass of a chemical compound.
The mass percentage of an element can be determined in two steps:
First, calculate the molar mass of the compound and then the percentage of each element by dividing the total mass of the element present in the compound by the molecular mass of the compound multiplied by 100.
Given, the molecular formula of the compound is NO.
The molecular mass of the NO = 30 g/mol
The mass percentage of the Nitrogen = (14/30) × 100 = 46.67 %
the molecular formula of the compound is NO₂.
The molecular mass of the NO = 46 g/mol
The mass percentage of the Nitrogen = (14/46) × 100 = 30.4 %
the molecular formula of the compound is N₂O.
The molecular mass of the NO = 44 g/mol
The mass percentage of the Nitrogen = (14/44) × 100 = 31.81 %
the molecular formula of the compound is N₂O₃.
The molecular mass of the NO = 76 g/mol
The mass percentage of the Nitrogen = (28/76) × 100 = 36.84 %

Some atoms disappear while others multiply to form the products
The atoms of the reactants always stay together to form the products
New atoms are formed which combine to make the products
Answer:
1st one is correct
The atom of the reactants unbound , rearrange, and then rebond to form the product
hope it helps
In a chemical reaction, the atoms of the reactants unbond, rearrange, and then rebond to form the products. Therefore, option A is correct.
What is chemical reaction ?Chemical reaction, the transformation of one or more chemicals the reactants into one or more distinct compounds, the products. Chemical elements or chemical compounds make up substances.
Combustion reaction, decomposition reaction, neutralization reaction, redox reaction, precipitation or double-displacement reaction, and synthesis reaction are some of the numerous types of reactions.
In a chemical reaction, bonds between molecules of the reactant are broken and new bonds between molecules of the product are established to create a new substance.
A chemical equation is nothing more than a mathematical statement that represents how reactants form products.
Thus, option A is correct.

Answer:
shift to restore equilibrium
Explanation:
Le Châtelier's Principle states that when a stress is applied to a system at equilibrium, the system will respond by shifting in the direction (either towards the products or reactants side) that opposes/ minimizes the effect of the stress.
Note that although the system tries to restore equilibrium, this equilibrium is a new equilibrium.
Equilibrium is the state of a reversible reaction when:
• two opposing reactions occur at the same rate;
• the concentrations of reactants and products are constant

A seedling is planted in soil that does not have any clay. What will most likely happen to the plant?
Answer:
Explanation:
Under good conditions the seedling can thrive in soil that does not have any clay as long as it gets the proper nutrients and right amount of sunlight/water that it needs. Clay in soil can provide the nutrients necessary for seedlings to thrive but can also cause many negatives. One such con of using clay is that it does not absorbe water very well, this ultimately causes the soil to become waterlogged and drowns the plants as no oxygen can pass through. This would ultimately kill the plants.
how many grams of iorn reacts with 71 grams of chlorine to produce 117 grams of sodium chloride
Answer:
The answer to your question is: 71 g of Chlorine
Explanation:
Na = 46 g
Cl = ?
NaCl = 117 g
Equation
2 Na + Cl₂ ⇒ 2 NaCl
46g X 117g
If we consider the law of conservation of matter, we know that the mass of the reactants equals the mass of the products, then
mass Na + mass Cl₂ = mass NaCl
46 g + X = 117
X = 117 - 46
x = 71 g of Chlorine

7. Concave and convex mirrors are called spherical mirrors because they are both made from the sphere. The difference between the two (in the simplest terms) is that diminished images form in convex mirrors while enlarged images form in concave mirrors.
8. The word ambulance is written inverted on an ambulance is because when a driver is driving and sees an ambulance in their rearview mirror, they can see the word ambulance the correct way. Otherwise the word ambulance would be backwards in the mirror. Thats why they write it backwards.
9. A plane mirror forms the image, object, etc, the same exact size that it is. The mirror can be small or large the size of the image will stay the same. So the difference between the object in a small and large plane mirror is none, there is no difference.
10. Car rearview mirrors are curved. This is to give a wider viewing angle. Flat surface mirrors give an accurate reflection. since the rearview mirrors are not flat, they are curved, they are less accurate, so thats why they have a warning label.
11. The sun emits the color of white. And as we know the color white consists of all colors. We can test this by putting the sunlight through a prism. since different colors of light travels at different speeds in the glass we cand see the light 'bent' .
12. Solar cookers use concave mirrors. This is because the mirror reflects the sunlight to a focal, 'center,' point. This center point will eventually heat up very, very hot.

How many grams are in 3.00 moles of carbon
Answer: Ok I think The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Carbon, or 12.0107 grams. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between moles Carbon and gram. 12 grams
This means that the atomic mass or atomic weight (12 grams) of carbon is equal to exactly 1 mole of carbon.
hope this helps have a awesome night/day❤️✨
Explanation:
There are 36 grams in 3.00 moles of carbon.
HOW TO CALCULATE MASS:
The mass of a substance can be calculated by multiplying the number of moles by its molar mass. That is;mass (g) = no. of moles (mol) × molar mass (g/mol)According to this question, 3 moles of carbon was given. The mass can be calculated as follows:atomic mass of Carbon = 12g/molMass = 12g/mol × 3molMass = 36g.
