Explanation:

Answer:

Water, in either liquid or solid form, is often a key agent of mechanical weathering. For instance, liquid water can seep into cracks and crevices in rock. If temperatures drop low enough, the water will freeze. ... Changes in temperature cause rock to expand (with heat) and contract (with cold).

Answer:

the rock has been rubbed away at for hundreds or thousands of years and the water steady washed the rock away. hope this helped.

Before

P1 : 748 mmHg

V1 : 22.5 L

After

P2 : 725 mmHg

V2 : ?

748 mmHg / 22.5 L = 725 mmHg / V2

Cross Multiply...

748 mmHgV2 = 16312.5 mmHgL

748 mmHgV2 / 748 mmHg = 16312.5 mmHgL / 748 mmHg

V2 = 21.808155 L

Answer:nuclear reaction

Explanation: Nuclear fusion is a type of nuclear reaction where two light nuclei collide together to form a single, heavier nucleus. Fusion results in a release of energy because the mass of the new nucleus is less than the sum of the original masses.

Fusion is the process that powers the sun and the stars. It is the reaction in which two atoms of hydrogen combine together, or fuse, to form an atom of helium. In the process some of the mass of the hydrogen is converted into energy.

Answer:

125°C/m

Explanation:

The difference in temperature will be:

35 - 10 = 25

The outer duct surface is heated 25°C by the air from 10°C to 35°C;

This heat gain is simply divided by 0.2m to get heat gain per unit length:

25/0.2 = 125

125°C/m

If you're American, this will be °F I believe, so the answer will be:

125°F/m

Answer:

205 calories.

Explanation:

According to the USDA, "Carbohydrates provide 4 calories per gram, protein provides 4 calories per gram, and fat provides 9 calories per gram." 9 grams of fat at 9 calories per equals 81 calories + 6 grams of protein at 4 calories per gram which equals 24 calories + 25 grams of carbohydrate at 4 calories per gram which is equal to 100 calories.

Total that all up and you get 81 cal + 24 cal + 100 cal=205 calories.

I don't know what kind of course this is for, but if they are incredibly picky, what we refer to as "calories" are actually kilocalories, which are equal to one thousand "real" calories each. However, I'm very confident that the correct answer is 205 calories.

The sandwich will provide 205 calories.

A calorie is an energy unit. It's the quantity of heat needed to increase the temperature of one gramme of water by [tex]1^{0} C[/tex] at one atmosphere of pressure.

Its is given that, Fat = 9 g, protein = 6 g, carbohydrate = 25 g.

It is known that, fat contains 9 calories / gram , carbohydrate contains 4 calories / gram and protein contains 4 calories / gram.

Now, adding all terms.

Total calories = (9×9) +(6×4) +(25×4)

= 205 calories.

Therefore, the sandwich will provide a total of 205 calories.

Answer:

Before we can sketch the Lewis structures of molecules, we must first understand the octet rule. The octet rule asserts that when atoms combine to create compounds, electrons are gained, lost, or shared among them, resulting in a stable electron configuration defined by eight valence electrons as a result. These rules are used in conjunction with the main-group components of the second period.

Answer:

Glycerin

Explanation:

The stronger the intermolecular forces of attraction the more energy is required to break those forces, if you need more energy to break these forces it means that these certain elements would have a higher boiling point. Which is why the answer is Glycerin, the highest boiling point of an element means that it has the strongest forces, which in this case is electrostatic forces.

Research scientific principles involved in water availability.

Explanation:

Before building or investment you always want to see and know what your up against and what the best way to help or solve is. Researching why there's a problem in water availability or/and the principals to water availability will help you see what the problem is with what's happening to and around the process and it's environment.

Answer:

-55°C

Explanation:

Bwcause 38°C is gonna make it colder so thats why you should use that.

Water has the strongest intermolecular forces followed by ethanol and diethyl ether has the least intermolecular forces.

From the table, we can see the vapor pressures of water, ethanol and diethyl ether. The boiling point of water is 100°C, the boiling point of ethanol is 80°C while the boiling point of diethyl ether is 40°C.

We can see that the vapor pressures and approximate normal boiling points of the substances varies with the nature of intermolecular bond forces in the molecule.

Water has highest boiling point and the lowest vapor pressure followed by ethanol. Diethyl ether has the highest vapor pressure and lowest boiling point from the data in the table.

Answer:

165.385 g/mol

Answer:

880.5

Explanation:

Express the result of adding 856.6g and 23.86g to the correct number of significant figures.

856.6 +23.86  = 856.6 + 23.9 = 880.5

The result of adding 856.6 g and 23.86 g after rounding off to correct significant figures is 856.6 + 23.9=880.5.

Significant figures are used for establishment  of a number which is presented in the form of digits. These digits give a meaningful representation  to the numbers.

The significant figures are the significant digits which convey the meaning according to the accuracy. These provide precision to the numbers and hence are called as significant numbers.There are rules for counting significant figures which are as follows:

1)All non-zero digits are significant .

2)All zeroes which occur between non-zero digits are significant.

3)All zeroes to the left and right of  a non-zero digit are not significant.

4) All zeroes on right  of decimal are significant if a non-zero number follows them.

5)All zeroes on right side of non-zero digit are significant.

The molecules of the two gases will have the same kinetic energy at room temperature.

The average kinetic energy of gaseous molecules can be calculated using the formula:

Kinetic Energy = 3/2RT, where R = constant and T = temperature in Kelvin

This means that the kinetic energy of a gaseous molecule is dependent on the temperature of the molecule only.

In other words, the molecular mass of molecules of gases has no bearing on the kinetic energy of each molecule.

Answer:

6. 15 oxygen atoms (The coefficient 5 is multiplied by the subscript 3 of oxygen)

7. The number "2" is the subscript.

The addition of more acid or base will increase the number of H3O+ and A- particles thereby decreasing and increasing the pH of the solution respectively.

An acid-base titration is one in which an acid is added to a given volume of base in order to neutralize it.

When more of acid is added to a solution of a base than is required to neutralize it, the solution becomes acidic.

Similarly, when more base is use to neutralize an acid than is required, the solution becomes alkaline.

In the given simulation, (H3O+) is the acid while (A-) is the base.

By adding increasing the quantity of acid added, the number of H3O+ particles will increase. This will reduce the pH of the solution.

Also, the adding more base to the solution, the number of A- particles in the solution will increase. This will increase the pH of the solution.

Therefore, addition of more acid or base will increase the number of H3O+ and A- particles thereby decreasing and increasing the pH of the solution respectively.
