Which statement describes an endothermic reaction? A. Energy is released by the reaction. B. Energy is absorbed by the reaction. C. No energy is transfered by the reaction. D. Energy is created in the reaction.
Answers
Answer:It's B energy is absorbed by the reaction,hope this helps
Explanation:
Any reaction in which energy is absorbed is said to be endothermic. Hence, option B is correct, but the rest are not correct.
What is an Endothermic Reaction?In every chemical process, energy is involved. When new bonds form in products, energy is produced. Reactant bonds are broken using energy. Exothermic reactions are those that produce more energy when new bonds form in the products than is needed to break existing bonds in the reactants.
In contrast, endothermic reactions are the opposite. Endothermic reactions release more energy when new bonds form in the products than is required to break bonds in the reactants.
During the reaction, a large amount of energy is absorbed.

What happens to the structure of an atom when the atom is ionised?
Answers
Answer: Explanation:
If the number of electrons is equal to the number of protons then the atom is uncharged and is electrically neutral. However, atoms can gain or lose electrons: increasing or decreasing the negative charge. Ionisation is the addition or removal of an electron to create an ion. ..Gaining an electron creates a negative ion.

A gas is compressed to 75cm3 to a volume of 30cm3. Its temperature remains the same The pressure of the gas after it has been compressed is 110 Pa. What was the pressure before it was compressed?
Answers
Given parameters:
Initial volume = 75cm³
New volume = 30cm³
New pressure = 110Pa
Unknown:
Initial pressure = ?
Solution:
Condition: temperature is constant
We simply apply Boyle's law to this problem:
" the volume of a fixed mass(mole) of a gas varies inversely as the pressure changes if the temperature is constant".
Mathematically;
P₁ V₁ = P₂ V₂
where P and V are pressure and volume values
1 and 2 are the initial and final states.
Input the parameters and solve for P₁;
P₁ x 75 = 110 x 30
P₁ = 44Pa
The initial pressure is 44Pa

In february a little town received snow on a daily basis. The first day they had 10 inches, 3 inches the second, 7 inches the 3rd, and 4 inches on the fourth day. What was the average snowfall?
Answers
Answer:
The average is 6
Explanation:
To find the average, you have to first add all the numbers. After you add all the numbers up, then you divide by how many numbers there are. This one had 4 numbers so you divide by 4
The average snowfall of the four days was 6 inches.
What is snow?
When atmospheric water vapor freeze into small ice crystals and falling in small white flakes or lying on the ground as a white layer, it is called snow.
In the question it is said that,
Amount of snow received by the town on first day = 10 inches.
Amount of snow received by the town on second day = 3 inches.
Amount of snow received by the town on third day = 7 inches.
Amount of snow received by the town on fourth day = 4 inches.
Total amount of snow received by the town on these four days = ( 10 + 3+ 7 + 4) inches.
=24 inches.
Hence, average amount of snow received by the town on these four days = total amount of snow received ÷ 4
= ( 24 ÷ 4) inches.
= 6 inches.
Hence, the average snow received by the little town was 6 inches on those days.

an antonym of lithium (Li) forms and an iconic bond with atom of chlorine CI to form lithium chloride. how are the valence electrons of these atoms rearranged to form this Bond ?
Answers
Li , which is located in group 1 of the periodic table, has one valence electron.
Chlorine, which is in group 17 of the periodic table, has seven valence electrons.
When the two atoms bond, lithium will lose one electron and form the lithium cation, Li + .
Since it loses one electron 7-1 = 6, there will be 6 valence electrons.

A 5000 kg truck and a 1000 kg car are traveling at constant speeds when they collide. What is true about the forces and accelerations on each?
Answers
And you can apply that all stuff you read from book
So yeah
Force is the physical action that can give acceleration to a body upon which it is applied
The true statements about the forces and accelerations of each when they collide are;
The force acting on the truck is equals the reactive force of the car The acceleration of the car is five times the acceleration of the truckThe reasons why the above statements are true are given as follows:
Known:
Mass of the truck, m₁ = 5,000 kg
Mass of the car, m₂ = 1,000 kg
Velocity of the truck = [tex]v_t[/tex]
Velocity of the car = [tex]v_c[/tex]
According to Newton's third law of motion, action and reaction are equal and opposite
The force applied by the truck, F = The reactive force by the carForce, F = Mass, m × Acceleration, a
Let a₁ represent the acceleration of the truck and let a₂ represent the acceleration of the car, we have;
F = 5,000 × a₁ = 1,000 × a₂
[tex]a_2 = \dfrac{5,000 \ kg}{1,000 \ kg} \times a_1 = 5 \cdot a_1[/tex]
Therefore;
The acceleration (rate of change of velocity) of the car, a₂ due to the collision is five times the acceleration of the truck due to the collisionLearn more about the about force and acceleration here:

How does using a ramp make work easier when loading a piano onto a truck three feet above the ground?
It allows a larger force to be applied over a shorter distance.
It allows a larger force to be applied over a longer distance.
It allows a smaller force to be applied over a shorter distance.
It allows a smaller force to be applied over a longer distance.
Answers
Answer:
It allows a smaller force to be applied over a longer distance.
Explanation:
A ramp is an example of an inclined plane that makes the movement of object easier above the ground level or higher surfaces.
In the given example, the sloping part of the ramp will support the weight of the piano as it moves up the slope and it will allow less force to be applied to move the piano above but the distance would be longer as the slant length or slope is the longest distance.
Hence, the correct answer is "d".
Answer:
D. It allows a smaller force to be applied over a longer distance.

Answers
Answer: There are different kinds of conductors, most notably electrical and thermal conductors. But they are often inclusive of each other (electrical conductors are typically good thermal conductors). A conductor transmits something through its body with high efficiency while an insulator does not transmit very well. In the case of electricity, a conductor transmits electrical energy between two points while an insulator blocks the flow of electricity. Two examples of conductors are copper and silver. Two examples of insulators are wood and styrofoam.

Newton's Second Law of motion
Explanation:
Newton's second law of motion states that 'the rate of change of the momentum of a body is directly proportional to, and in the same direction as, the net force acting on it.' This law applies to the given situation stating that 'a motorcycle can reach a speed of 60mph much faster than a minivan' as the smaller mass accelerates more quickly than the larger. This is because the van would require a more stopping distance as it would be difficult to decelerate due to the heavy mass. While for a motorcycle, it would be much easier to decelerate due to lesser mass. Thus, Newton's second law applies here.
