Answer:

I would say proton and electron are the two most important subatomic particles in an atom

Explanation:

The number of protons inside a nucleus must equal to the number of electrons outside of the nucleus. This number determines all the chemical properties of the atom, which governs the behaviors of all matters in our world.

Answer: In order for reflection to occur, the wave must “bounce off” an object

Explanation: For example if your looking in the mirror the waves are bouncing off the mirror to reflect your image

In order for reflection to occur the waves must an object bounce off.

The reflection of light can be described as when a ray of light approaches a smooth polished surface and the light ray bounces back. The incident light ray on the surface is reflected off the surface. The ray of light that bounces back is known as the reflected ray.

If a perpendicular is drawn on a reflecting surface known as normal. The angle of incidence and angle of reflection of light are equal to each other.

The laws of reflection tells about the reflection of incident light on reflecting surfaces, such as mirrors, smooth metal surfaces and clear water.

According to this, the incident ray, the reflected ray and the normal lie in the same plane and the angle of incidence is equal to angle of reflection of light rays.

Different types of reflection of light are regular reflection or specular reflection, Diffused reflection, and Multiple reflection.

First:

we can start off by turning the fractions into decimals

so 2/3=0.66

and 3/5=0.60

and we add the whole number

 3.66

- 2.60

which leaves you with 1.06

all that's left is turning it into a fraction

Combustion is familiar to all of us, but many do not realize that it is essentially a chemical reaction. In the process of combustion, two ingredients (biomass and oxygen) are combined in a high temperature environment to form carbon dioxide, water vapor, and heat

Explanation:

Combustion of Fossil Fuels. Combustion is a reaction with oxygen. In the case of the combustion of fossil fuels, the combustion reaction is what we think of as a burning process. In the combustion reaction, the species reacting with the oxgyen is oxidized (because oxygen is very electronegative).

Answer:

Geothermal provides a reliable source of energy as compared to other renewable resources such as wind and solar power. This is because the resource is always available to be tapped into, unlike with wind or solar energy.

Explanation:

Because its source is the almost unlimited amount of heat generated by the Earth's core. Even in geothermal areas dependent on a reservoir of hot water, the volume taken out can be reinjected, making it a sustainable energy source.

Answer:

A geothermal power plant gets energy from the heat deep below the surface of the earth. Shafts are drilled down, often as deep as several kilometres, one to pump water down to the hot rocks, and another nearby which will allow the heated water (or steam) to rise up. This steam is then used to spin electricity turbines to generate electricity.

The result of the procedure with the nail ended up going through reduction while the copper strip went through oxidation. The copper strip is the anode and the nail is the cathode. The anode is the + and the cathode is the - . Both the copper strip and the anode are placed in a tank filled with electrolyte solution. The direction of the flow goes from the positive to the negative (anode to the cathode).

Explanation:

I was doing the assignment too, hope this helps :)

The result of the procedure with respect to the coin and nail should be explained below.

Here the nail should be ended up through the decrease while on the other hand, the copper strip should be went through oxidation.

Here the copper strip should be considered as anode and nail should be considered as the cathode. Here the  anode should be + while the cathode should be -.

Both should be placed in the tank that should be filled with the electrolyte solution.

Answer:

1.02x10^24 atoms

Explanation:

The coefficients (the numbers before each susbtance) in this equation tell us that for every 2 moles of hydrogen used, there will be 1 mole of tin produced. This is a fixed ratio, which means if we use 4 moles of H2, 2 moles of tin will be produced.

One mole contains Avogadro's number of atoms (6.02 x 10^23). So two moles would contain twice as many atoms as this.

2 x 6.02x10^23 = 1.02x10^24 atoms.

Answer:

1.2044  x 10^24 atoms

Explanation:

The equation of the reaction is given as;

SnO2 + 2 H2 → Sn + 2 H2O

From the reaction;

2 ml of H2 produces 1 mol of Sn

4 mol of H2 would produce x mol

2 = 1

4 = x

Solving for x;

2x = 4

x = 4 /2 = 2 mol

The relationship between mol and atoms is given as;

1 mol = 6.022 × 10 23 atoms

2 mol = x

x = 2  * 6.022 × 10^23

x = 12.044 x 10^23 = 1.2044  x 10^24 atoms
