Answer: 9L
Explanation:
(6 x 300) = 1800 / 200 = 9
You start with a container that is 8L big and the temperature in the room is 326K.
If the you take the container out in the heat at 352K, how big will it get?
Answer:
The new volume is 8.64 L.
Explanation:
Charles's Law consists of the relationship that exists between the volume and the temperature of a certain quantity of ideal gas, which is maintained at a constant pressure. For a given sum of gas at constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases.
In summary, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the quotient that exists between the volume and the temperature will always have the same value:
[tex]\frac{V}{T} =k[/tex]
Being an initial state 1 that modifies its conditions until a final state 2, it is fulfilled:
[tex]\frac{V1}{T1} =\frac{V2}{T2}[/tex]
In this case:
V1= 8 LT1= 326 KV2= ?T2= 352 KReplacing:
[tex]\frac{8L}{326 K} =\frac{V2}{352 K}[/tex]
Solving:
[tex]V2=352 K*\frac{8L}{326 K}[/tex]
V2= 8.64 L
The new volume is 8.64 L.
what happens to the electrons in an ionic bond and a covalent bond?
Answer:
In ionic bonding, atoms transfer electrons to each other. Ionic bonds require at least one electron donor and one electron acceptor. In contrast, atoms with the same electronegativity share electrons in covalent bonds, because neither atom preferentially attracts or repels the shared electrons.

Explanation:
To make 4.25 L of 3.0 M NaOH solution how much of a 9.0 M NaOH solution would be needed?
Answer:
1.41 L
Explanation:
Initially the concentration of NaOH was 9.0M (say M1) finally the concentration becomes 3.0M (say M2)
intial volume (say V1) is to be calculated when the final volume (say V2) is 4.25L
we have,
M1V1=M2V2
or V1=(M2V2)/M1= 3.0×4.25/9.0= 1.41L
Hence 1.41 L of 9.0M solution is required to prepare 4.25L of 3.0M NaOH solution

Question 4 options:
More concentrated sunlight makes for cooler temperatures
The summer solstice occurs when the earth is in a position so that the North Pole is tilted most directly toward the sun.
The atmosphere absorbs some of the sun's rays
The tilt and revolution of the earth as it moves around the sun cause the different seasons of the year.
The summer solstice occurs when the earth is in a position so that the North Pole is tilted most directly toward the sun.
What is the summer solstice?The summer solstice happens when a pole on either the northern hemisphere or southern hemisphere, is found most inclined toward the sun.
The summer solstice then represents two different moments during the year according to the hemisphere. The summer solstice happens on June 21, and this period represents the longest day of the year.In conclusion, the summer solstice occurs when the earth is in a position so that the North Pole is tilted most directly toward the sun.

100 cm3 of the copper sulfate solution contains 1.8 g of copper sulfate.
Calculate the mass of copper sulfate in 25 cm of this copper sulfate solution.
Answer:
The mass of copper sulfate in 25 cm³ of the copper sulfate solution is 0.45 g
Explanation:
The given parameters are;
The volume of the copper sulfate solution = 100 cm³
The mass of the copper sulfate in the solution = 1.8 g
Therefore, the mass of copper sulfate in 25 cm³ of the solution is given as follows;
The mass of copper sulfate in 100 cm³ of the solution = 1.8 g
The mass of copper sulfate in 1 cm³ of the solution = 1.8 g/100 = 0.018 g
Therefore;
The mass of copper sulfate in 25 × 1 = 25 cm³ of the solution, m = 25×0.018 g = 0.45 g
∴ The mass of copper sulfate in 25 cm³ of the solution, m = 0.45 g

How do neutral metal atoms form ions?
Answer:
Neutral atoms can be turned into positively charged ions by removing one or more electrons. ... Atoms that gain extra electrons become negatively charged. A neutral chlorine atom, for example, contains 17 protons and 17 electrons. By adding one more electron we get a negatively charged Cl- ion with a net charge of -1.

how are heat, temperature, and thermal energy related?
Answer:
Heat, temperature, and thermal energy are related because they all work with each other.
Explanation:
First of all, everything start's off with temperature. It starts off low. But when heat is added to it, it rises and the temperature goes up. This causes thermal energy to the objects touching it. The hotter it is the faster the particles move and the more kinetic energy they have.
Which led to the formation of oceans after water on Earth’s surface evaporated?
Answer:
Explanation:
En tiempos de la formación de la Tierra, el planeta se encontraba a una elevada temperatura, por lo que no le resultaba posible retener ningún tipo de atmósfera. La ausencia de nubes de vapor de agua y océanos en la tierra primigenia era causa directa de su temperatura, ya que el agua se encontraba combinada con los materiales rocosos.
Ammonia (NH3) is widely used as a fertilizer and in many household cleaners. How much ammonia is produced when 5.81 mol of hydrogen gas react with an excess of nitrogen gas?
Answer:
65.841 g
Explanation:
The balanced equation for this reaction is;
N2 + 3H2 → 2NH3
From the question, we are interested in ammonia and the hydrogen gas.
From the equation
3 mol of H2 produces 2 mol of NH3
5.81 mol would produce x
Solving of x;
x = 5.81 * 2 / 3
x = 3.873 mol
Converting to mass;
Mass = Number of moles * molar mass
Mass = 3.873 * 17 = 65.841 g
