Hello, Flashligh explain where the energy comes from and how it is affecting change or putting an object in motion

Answers

Answer 1

Answer:

Our energy supply comes mainly from fossil fuels, with nuclear power and renewable sources rounding out the mix.

The energy associated with an object's motion is called kinetic energy. Kinetic energy is the energy of motion. All moving objects have kinetic energy

Explanation:

Answer 2

Answer:

Kinetic energy is the energy of motion. All moving objects have kinetic energy. When an object is in motion, it changes its position by moving in a direction: up, down, forward, or backward. As he winds up and releases the ball, the stored energy is changed into kinetic energy, the energy of motion!So that , energy comes from and how it is affecting change or putting an object in motion.

Heavy rains fill a reservoir, causing the dam that holds the water to break. As a result, the areas downstream are suddenly flooded. Which question would a scientist seek to answer?

Answers

Answer:

"How to prevent the collapse of the dam that contains water from heavy rains?"

Explanation:

Scientists must work to create innovations capable of bringing benefits to human life and combating disadvantageous and harmful situations. The overflow of dams is something very harmful, as the resulting flooding can cause structural, economic and even public health problems. When this overflow is caused by natural elements, such as heavy rains, the work of scientists in solving these issues is even more important and necessary. In order to resolve the dam failure caused by excess rainwater, scientists must work to answer the following question:

Which coefficients correctly balance the formula equation below?

AgNO3 + CuCl2 → AgCl + Cu(NO3)2



2, 1, 2,1



1, 1, 3,1



2, 2, 3,1



2, 1, 1,2

Answers

Answer:

2, 1, 2,1

Explanation:

The chemical equation of the reaction given in this question is as follows:

AgNO3 + CuCl2 → AgCl + Cu(NO3)2

The reaction is between silver nitrate (AgNO3) and copper (I) chloride (CuCl2) to form silver chloride (AgCl) and copper nitrate (Cu(NO3)2.

However, this above equation is not BALANCED because the number of atoms of each element on both sides of the equation does not equate i.e. are not the same. To balance the equation, we have to make use of COEFFICIENTS, which are numbers used in front of each element in order to balance the equation.

The balanced equation is as follows:

2AgNO3 + CuCl2 → 2AgCl + Cu(NO3)2

From the above balanced equation, we can observe that coefficients used to balance the equation is in the order: 2, 1, 2,1

A se ion has a mass number of 77
and a charge of −2
. Determine the number of neutrons, protons, and electrons in this ion.

Answers

Answer: The number of protons are 34, number of neutrons are 43 and number of electrons are 36 in the given Se ion

Explanation:

The atom consists of 3 subatomic particles:

Protons: They are positively charged particles present in the nucleus of an atom.Electrons: They are negatively charged particles present in the orbits around the nucleus of an atom.Neutrons: They are neutral particles present in the nucleus of an atom.

The mass number is the sum of the number of protons and number of neutrons in the nucleus of an atom. These are known as nucleons

The atomic number is defined as the number of electrons or number of protons present in an atom.

We are given:

A Se ion having mass number 77

Atomic number of Se = 34

Number of protons = 34

Number of neutrons = 77 - 34 = 43

Number of electrons = Atomic number - Charge

Charge = -2

Number of electrons = [34 - (-2)] = [34 + 2] = 36

Hence, the number of protons are 34, number of neutrons are 43 and number of electrons are 36 in the given Se ion

Define the boiling and evaporation using kinetic theory

Answers

Answer:

Explanation:

By the kinetic molecular theory (particle model), all matter consists of particles, there are spaces between the particles, the particles are in constant random motion, and there are forces of attraction and repulsion between the particles.

Furthermore, temperature is defined to be a measure of the average kinetic energy of the particles.

Evaporation is a change of phase from liquid to gas explained as follows :

When particles in the liquid phase are heated, they gain kinetic energy and move faster and further apart. Eventually they have enough energy to escape the forces of attraction holding them together in the liquid phase and they move very fast and far from each other and exist in the gaseous phase.

When a catalyst is added to a chemical reaction it provides a new reaction pathway that results in a different

Answers

Answer: That results in a different ALTERNATE pathway which has a LOWER ACTIVATION ENERGY.

Explanation:

There are many factors that affects a chemical reaction, these include'

--> surface area

--> concentration,

--> temperature,

--> pressure and

--> presence of CATALYST.

A CATALYST is defined as the substance that has the ability to alter the rate of a chemical reaction. Many reaction very slowly when left alone, but become faster when other substances are added. Such substances that merely alter the rate of reactions but do not take part in the reactions are called CATALYSTS.

Activation energy is defined as the energy barrier that must be overcome before a reaction takes place. A catalyst is able to increase the rate of a chemical reaction by decreasing the activation energy of the chemical system.

A catalyst provides an ALTERNATE PATHWAY for the reaction that has a LOWER ACTIVATION ENERGY. When activation energy is lower, more reactant particles have enough energy to react, so the reaction occurs faster.

what mass of water will be formed when 3g of hydrogen react with 30g of oxygen?​

Answers

Answer:  Write down the chemical equation first;

2H2 + O2 —-> 2H2O

2. Since the mass is given, use it to calculate the mole for each reactant;

mole = mass / molar mass

mole of H2 : 8/2 = 4 mole

mole of O2 : 30/16(2) = 0.9375 mole

Now, if you're not sure which reactant to use to calculate the mass of H2O using ratio since both answer are different, find the limiting reactant.

From the equation;

2 mol of H2 -> 2 mol of H2O

4 mol of H2 -> (4*2)/2 = 4 mol of H20

______________________________________

1 mol of O2 -> 2 mol of H2O

0.9375 mol of O2 -> (0.9375*2)/1 = 1.875 mol of H2O

Let's take a look at both numbers. Since H2 produces more water than O2, O2 will be the limiting reactant as it has the least mole of H2O. So now we are going to use O2 as our limiting reactant. Use the formula to calculate mass of water using mole.

mass of H2O : 1.875*(16+2) = 33.75 g

Is the following nuclear equation balanced?

No
Yes

Answers

Answer:

Yes.

The nuclear equation {226/88 Ra → 222/26 Rn + 4/2 He} is balanced. As we know that an alpha particle is identical to a helium atom. This implies that if an alpha particle is eliminated from an atom's nucleus, an atomic number of 2 and a mass number of 4 is lost.

Therefore, the equation will be reduced to:

226 - 4 = 222

88 - 2 = 86

Hence, the equation is balanced.
