Explanation:
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.

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.

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.

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.

Based on what you have read about wind turbines and dams, how does a generator work? A loop of Answer spins in a Answer field, producing Answer current. Item
Based on what you have read about wind turbines and dams, how does a generator work? A loop of ______ spins in a ______ field, producing ______ current.
Answer:
Wire
Magnetic
Electric
Explanation:
The generator works on the principle of converting mechanical energy into electrical energy.
For example in a wind turbine generator, the mechanical energy is the wind that pushes the blades of the turbine directly that leads to conversion of this it's linear motion to the rotary motion required to make rotor of the generator to spin. Finally, the harder the wind pushes, the more the mechanical energy applied and consequently, the more electrical energy can be generated.
Now, all generators work because of the effect of the magnetic field moving past an electrical coil.
Thus, the movement of a magnet across a single loop of wire produces a voltage that is induced within the wire loop as a result of the magnetic field produced by the magnet.
As a voltage is induced across the wire loop, electrons begin to flow around the loop thereby generating electric current.
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.

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.
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
