Find the molar mass for NaNO3

Answers

Answer 1

Molar mass

= Atomic mass of Na + Atomic mass of N + Atomic mass of O3

= 23 + 14 + (16×3)

= 23 + 14 + 48

= 85 g per mole

I need help with figuring out how to calculate the frequency of light, because my teacher's notes are generic. When I asked her about it on top of another question; she only answer that other question" and never talked about the notes.

Answers

Answer:

See explanation

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.

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.

At a constant temperature, 2L of a gas at 4atm of pressure is expanded to 6L. What is the new pressure? Please show steps!!

Answers

Answer:

The answer is 1.33 atm

Explanation:

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

[tex]P_1V_1 = P_2V_2[/tex]

Since we are finding the new pressure

[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]

From the question we have

[tex]V_2 = \frac{2 \times 4}{6} = \frac{8}{6} = \frac{4}{3} \\ = 1.333333...[/tex]

We have the final answer as

1.33 atm

Answers

Answer:

Chemical WeatheringSlowly

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.

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.

Why are ions usually formed during the interaction of metal with nonmetal and not between two metals? ​

Answers

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.

When writing a formula for a compound having a transition metal in it, _____.
it is sometimes necessary to use the Roman numeral as the assigned charge of the metal
it is sometimes necessary to include a Roman numeral after the symbol of the metal
it is always necessary to include a Roman numeral after the symbol of the metal
it is always necessary to use the Roman numeral as the assigned charge of the metal

Answers

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

The total amount of energy before and after a chemical reaction is the same. Therefore, energy is _____.
created

destroyed

converted

conserved

Answers

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

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

How much energy would be needed to raise the temperature of a 5kg block of concrete by 10°C?

Answers

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.

What is energy?

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

Electrical energyChemical energyMechanical energyThermal energyNuclear 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.

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

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.

Answers

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
