Name 3 sources of carbohydrates for the production of an alcoholic drink

Answer:

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\ [/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{3.612 \times {10}^{24} }{6.02 \times {10}^{23} } \\ [/tex]

We have the final answer as

Hope this helps you

Answer:

Option (a) is the correct answer.

Explanation:

The law of conservation of energy states that energy can neither be created nor it can be destroyed. It can only be transformed from one form to another.

Therefore, the total amount of energy before and after a chemical reaction is the same. Thus, energy is conserved.

Therefore, we can conclude that option (a) is the correct answer.

Answer:

conserved

Explanation:

law of conservation of energy says that energy can neither be created or destroyed

Answer:

Yes, NaNO3 is the formula for sodium nitride.

Answer:

5 x 10 x 3200 = 170 000J or 170kJ

Explanation:

i searched it lol

The energy needed to raise the temperature of a 5 kg block of concrete by 10° C is 170 000J or 170kJ.

Energy is defined as a quantitative property that is transferred to a body or to a physical system. It can also be defined as capacity of doing work.

There are basically five forms of energy

Heat energy = mass x heat capacity x raise in temperature

                     = 5 x 3200 x 10

                     = 170000 J or 170 kJ

Thus, the energy needed to raise the temperature of a 5 kg block of concrete by 10° C is 170 000J or 170kJ.

Answer:

The correct option is;

It is always necessary to include a Roman numeral after the symbol of the metal

Explanation:

The transition metals can form ionic compounds with other elements by giving different number of electrons such that the transition metals can combine to form compounds in which they have different oxidation states

Therefore, in a compound formed by a transition metal, the value of the transition metal's valency or oxidation state in the compound is indicated by the inclusion of an equivalent Roman numeral after the transition metal in the name of the chemical formula of the compound

Explanation:

1. Methane

2. Diamond

3. not sure : )

Explanation:

Ions are always formed when metals and non-metals interact because metals are electropositive. They willing release electrons to non-metals that are electronegative.

This activity results in charge separation. The transfer of electrons from one specie to another is what results in an ionic bond and the precedence of charged particles.

Between non-metals, the electrons are jointly shared. Therefore, there is no charge separation.

Element Y,  or the third option

Explanation:

Alkanes are insoluble in water, but soluble in ether.  Their boiling points are pretty low, barely reaching 200 degrees, so element Y is an alkane.

Answer:

Explanation:

The general formula used to obtain the frequency of a wave is;

v=λf

where;

v = speed of the wave

λ= wavelength of the wave

f= frequency of the wave.

Now, the speed and wavelength of light in various media are known.

If we plug the value of the speed of light and the wavelength of light into the formula given above, we can obtain the frequency of light.

The frequency of a photon of light can also be obtained from Plank's equation;

E= hf

where;

E =energy of the photon of light

h = Plank's constant

f= frequency of the photon.

This is used when the energy of the photon of light is supplied or can be calculated using the wavelength of light provided in the problem.

Answer:

CLEANER

Explanation:

Independent variable is the variable in an experiment that is changed or manipulated by the experimenter in order to bring about a measurable response.

In this question, Marie notices that the current cleaner she is using on her shower is not cutting through the hard water build-up that has accumulated. She decides to purchase 3 other cleaners to see if one of them will do a better job of cutting through the stains. The CLEANERS being changed in this experiment is the INDEPENDENT VARIABLE.

Answer:

3.97 M

Explanation:

Given data:

Initial volume V₁  = 318 mL

Initial molarity M₁ = 5.75 M

New volume V₂=  461 mL

New concentration M₂= ?

Solution:

New volume V₂= 143 mL+ 318 mL

New volume V₂= 461 mL

Formula:

M₁V₁  = M₂V₂

M₂ = M₁V₁ / V₂

M₂ = 5.75 M × 318 mL / 461 mL

M₂ = 1828.5 M. mL/ 461 mL

M₂ = 3.97 M

Condensation

Explanation:

Answer:

A.  5 N to the left

Note: The question is incomplete. The complete question is given below:

With a force of 5 newtons, Amanda pushes the stack of books to the right. At the same time, Jeremy, her little brother, pushes the stack of books to the left with a force of 10 newtons.

What is the direction and magnitude of the resulting force?

A.  5 N to the left

B.  5 N to the right

C.  10 N to the right

D.  10 N to the left

Explanation:

Forces are vector quantities.

Vector quantities are quantities that can be represented both in magnitude and direction.

Forces have both magnitude and direction. Forces can be directed positively or negatively.

For example, in the question above, if forces acting to the right are considered to be in the positive direction, forces acting to the left are considered to be acting in a negative direction.

In the addition of forces, both their magnitude and direction are taken into consideration.

In the example above, taking forces acting to the right as positive and to the left as negative, the sum of the forces is:

Resultant force, F = (5 N) + (-10N)

F = -5 N

Therefore, the net force is 5 N and is directed towards the left

Answer:

5 N to the left

Answer #1: Lithospheric plates are part of a planetary scale thermal convection system. The energy source for plate tectonics is Earth's internal heat while the forces moving the plates are the “ridge push” and “slab pull” gravity forces. It was once thought that mantle convection could drive plate motions.

Answer #2:Subduction is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced to sink due to high gravitational potential energy into the mantle. Subduction zones are sites that usually have a high rate of volcanism and earthquakes.

Explanation:

Answer:

Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. All magma develops underground, in the lower crust or upper mantle, because of the intense heat there. first question Natural non-living things: They are found in nature and are not made by man. Examples: Sun, moon, stars, sky, clouds, rocks, mountains and many more. Man-made non-living things: They are made by man. Examples: Toys, chairs, tables, beds, houses, buildings, trains and many more. second question Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock. The parent rock can be either sedimentary, igneous, or even another metamorphic rock. The word "metamorphic" comes from Greek and means "To Change Form". third question.

Explanation:

Building bricks deteriorate overtime due to chemical weathering from moisture constantly in contact with it overtime, as well temperature changes. Their topmost layers leach after continuous attack, and are eroded. thereby causing them to break away most times.

This cycle takes place overtime and is not a quick action.

I hope this is easy to understand.

Explanation:

Put the pan into a water-containing dish and mix well. Now use a strainer to transfer the solution into another jar. The salt should disappear in it. 

And using a tube with a filtrate, transfer the salts that has sand into another bottle with a filtrate. Therefore the sand is split. Eventually, when all the water vaporizes and the salt stays in the bottle, leave the extra solvent and heat it.

Answer:

Explanation:

The new pressure can be found by using the formula for Boyle's law which is
