Answer 1

Answer:

Pretty sure it's Polar Covalent because they are proven to have a higher melting point than both Ionic, and Non Polar Covalent substances. That is due to the fact that it takes more energy to separate molecules from each other, which is what the molecules in Polar Covalent substances do, which is why it has a higher boiling point than the other choices.

Answer:

Liquid, Gas and Plasma

Explanation:

➨Think about it like this if you put a material made out of these and flipped it over which one would have the most effect of change in shape?

▶Liquid molecules slide past each other meaning they are not held in place.

▶Gas molecules are "excited" they bounce around everywhere meaning they are not held in place.

▶Plasma has no fixed shape or volume so it cant be held in place!

▶Solid molecules have a fixed shape so they cannot move on their own.

Answer:

5 moles

Explanation:

Given data:

Number of moles of HCl = 5 mol

Number of moles of H₂O produced = ?

Solution:

Chemical equation:

Why is NCl3 not soluble in water?

Answers

Answer:

Explanation:

NCl3 does not dissolve in water because it is a nonpolar molecule which is different with water. NCl3 is nonpolar due to the difference in electronegativities between 3 atoms of Cl and 1 atom if N2.

Answer:

A polar solute dissolves into a polar solvent and a non-polar compound dissolves into a non-polar solvent, this rule is known as "like dissolves like".

Q 1. Element M is a metal that forms compounds of the type MX2, MX3, and MX4, where X is a Chlorine (Cl).
I) What is the expected trend in the ionic radius of M in these compounds?
II) Arrange these compounds in order of decreasing ionic radius of M.

Do not respond if u don’t know the answer. I’ll report it and u will get a warning.

Answers

Answer:

See explanation

Explanation:

The ionic radius of metal M decreases as the magnitude of charge on the metal M increases. The ionic radius is the distance between the nucleus and the electron in the outermost shell of an ion. So, ionic radius decreases with increasing positive charge.

We can see that from the various formulae in the question that the metal forms cations M^2+, M^3+ and M^4+ respectively. The order of decreasing ionic radius of the compounds is;

MX2 > MX3 > MX4

a wet 43.2 g sample of copper sulfate heptahydrate is heated until only copper sulfate remains. the mass of the water lost is 34.1 g. what is the mass of copper sulfate

Answers

Answer:

9.1g

Explanation:

Given parameters:

Mass of copper sulfate heptahydrate  = 43.2g

Mass of water lost  = 34.1g

Unknown:

Mass of copper sulfate = ?

Solution

The copper sulfate heptahydrate is made up of the copper sulfate and water of crystallization which makes it wet.

Mass of copper sulfate heptahydrate  = mass of copper sulfate + mass of water

Mass of copper sulfate = mass of copper sulfate heptahydrate - mass of water

Mass of copper sulfate = 43.2g  - 34.1g = 9.1g

The mass of copper sulphate that is produce from a wet 43.2 g sample of copper sulphate heptahydrate that is heated until only copper sulphate remains (mass of water lost is 34.1 g)  is 9.1 grams.

Using the law of conservation of matter, the mass of the reactant is equals to the mass of the product.

Therefore,

CuSO₄7H₂O → CuSO₄ + 7H₂O

mass of CuSO₄7H₂O = 43.2 g

mass of CuSO₄ = x

mass of H₂O = 34.1 g

mass of  CuSO₄ = 43.2 - 34.1

mass of  CuSO₄ = 9.1 g

Liquid nitrogen, which has a boiling point of −195.79°C, is used as a coolant and as a preservative for biological tissues. Is the entropy of nitrogen higher or lower at −200°C than at −190°C? Explain your answer. Liquid nitrogen freezes to a white solid at −210.00°C, with an enthalpy of fusion of 0.71 kJ/mol. What is its entropy of fusion? Is freezing biological tissue in liquid nitrogen an example of a reversible process or an irreversible process?

Answers

Answer:

Explanation:

Entropy is measure of disorder so as we lower the temperature of gas , its entropy decreases .

Hence at - 200°C entropy of nitrogen will be less than that at - 190°C .

At freezing point ,

entropy of fusion  = latent heat / freezing temperature

= .71 kJ / ( 273 - 210 )

= 710 / 63 J mol⁻¹ K⁻¹ .

= 11.27 J mol⁻¹ K⁻¹ .

entropy of fusion = 11.27 J mol⁻¹ K⁻¹ .

Suppose the moon rotating on its axis just as quickly as earth would we still always see the same side of the earth explain

Answers

Answer:If the Moon rotated as fast as the Earth would we only see one side of the Moon? ... The Moon, on the other hand, rotates once around its own axis every 28 days, and once around the Earth in that same 28 days. The end result of this combination is that the same side of the Moon is always facing the Earth

Explanation:

The moon rotates on its axis along with revolution around earth. Both time are synchronized due to the gravitational pull and tides of earth. That's why we are seeing the same side of moon.

What is gravitational pull?

Gravitational force is a force by which a body attracts other body towards its centre of mass. By the gravitational pulling of earth, we are all standing on the ground.

Gravitational force depends on the mass of the body.  Earth attracts its nearby objects by gravitational force and thus towards moon also. In fact if moon is quickly rotating on its own axis we would see the other side of moon.

But the fact is that the earth gravitational pulling and tides of ocean make  its own gravitation also make the moon tilted slightly and assume a prolate shape. The rotation of moon is thus tidally locked and synchronized with its revolution.

Hence, moon rotates exactly once every time as it revolve around earth in a tilted axis. Thus the other side will always  hide from the earth's surface.
