When KCL dissolved in ethanol, what is the intermolecular attraction between K+ ions and ethanol molecules?

Answers

Answer: Ion-Dipole

Explanation: I took the CK-12 practice and got it right

When KCL dissolved in ethanol, the intermolecular attraction between K+ ions and ethanol molecules is ion - dipole interaction.

What is an ion dipole interaction ?

The term ion-dipole interaction is defined as the intermolecular force of attraction between cation or anion and a molecule. It is present in the solution where ionic compounds dissolve in polar solvents.

Due to the polar O-H group's presence in the molecule, ethanol is a polar substance. Thus, the molecule has a dipole moment. The dipole's positive end rests on hydrogen, and its negative end rests on oxygen.

K+ ions can interact with the ethanol's negative end of the dipole through ion-dipole interaction when KCl is dissolved in the alcohol.

Thus, When KCL dissolved in ethanol, the intermolecular attraction between K+ ions and ethanol molecules is ion - dipole interaction.

certain conductor with a resistance of 10 Ohms is crossed by an electric current of intensity 100 mA. What is the potential difference at the terminals of that conductor?

Answers

Answer:

1.0 V

Explanation:

Step 1: Given data

Resistance of certain conductor (R): 10 ΩCurrent's intensity (I): 100 mAPotential difference at the terminals of that conductor (V): ?

Step 2: Convert "I" to Ampere

We will use the conversion factor 1 A = 1000 mA.

100 mA × 1 A/1000 mA = 0.100 A

Step 3: Calculate the potential difference

We will use Ohm's law.

V = I × R

V = 0.100 A × 10 Ω = 1.0 V

Sand is composed of silicon dioxide SiO2. A 210 gram sample has how many moles?

Answers

To convert grams to moles you must divide by the molar mass of the molecule
SiO2 molar mass=60.083
210/60.083=3.495
This sample has 3.495 moles of SiO2

The number of moles of 210 gram sample of sand contains 3.5 moles of mole of SiO₂

Sand is composed of silicon dioxide (SiO₂).

Therefore, let's calculate the molecular mass of SiO₂ . Therefore,

Molecular mass of SiO₂

The molecular mass of the compound is the sum of the atomic mass of the compound.

SiO₂ = 32 + (16 × 2) = 28 + 32 = 60 g/mol

Therefore,

60 g = 1 mole of SiO₂

210 g = ?

cross multiply

number of moles = 210 / 60

number of moles = 21 / 6

number of moles = 3.5 moles

I am worried about your proposal to install a groundwater heating system in my daughter’s school.

I don’t think that water at a temperature of 30°C has enough energy to heat the school. If the school is too cold, the students won’t be able to focus on learning.
Respond to David Li’s letter. Explain how the groundwater system could heat the air in the school.

Answers

Answer: The temperature would increase assuming it is 30 degree water causing a change in the temperature and assuming it is a seismic groundwater source you are using the earths core to heat the school so it would likely be a stable energy source. There are very few places on the planet where that warm of water is accessible without drilling really deep into the core but if it is there and is a stable fault then the energy would be consistent and stable.

The groundwater system can heat the air in the school by transferring the heat in the ambient atmosphere of school.

Groundwater heating system:

Although the temperature of the ground water is not much but the amount of groundwater is too much.

This large amount water slowly releases heat energy which is transferred in the ambient atmosphere of school.

Therefore, the groundwater system can heat the air in the school by transferring the heat in the ambient atmosphere of school.

The sound made by crickets occurs when the male crickets rubs its two hind legs together. Which type of energy transformation results in the sound made by crickets?
A.sound energy to thermal energy
B.thermal energy to chemical energy
C.mechanical energy to sound energy
D.mechanical energy to chemical energy

Answers

Answer:

You can simply use process of elimination to find your answer. The only option that results in SOUND energy is C. Therefor your answer would be C.

Explanation:

The rubbing of the hind legs by crickets converts the mechanical energy to sound energy. Thus, option C is correct.

Crickets have been the nocturnal animals that sleep in the daytime and were awake at the night. The crickets have been consisted of the front limbs and hind limbs with a pair of wings that support them to fly.

The crickets make the sound by the rubbing of the legs, thereby creating the vibrational sounds that have been sound energy.

The rubbing of legs has been utilized as the mechanical energy or the energy of doing work. The mechanical energy has been converted to the vibrational energy that contributes to the energy of the sound waves, thereby the sound energy.

Thus, the rubbing of the hind legs by crickets converts the mechanical energy to sound energy. Thus, option C is correct.

What is a function of the backbone in animals?
A. It protects against predators.
B. It regulates blood glucose.
C. It surround the spinal cord.
D. It limits movement.

Answers

Answer:

C - It surrounds the spinal cord.

Explanation:

Option A would be incorrect. Having a protective shell on an animal’s back would be one of the ways they would be protected against predators. And having a backbone wouldn’t really make a good shield against predators.

Option B is incorrect. The pancreas regulates blood glucose, not the backbone.

Option D would also be incorrect. It doesn’t limit movement unless it’s bent or positioned abnormally. Or unless it’s broken or malfunctioned.

The only option that is correct is option C. Hope it helps. ^^
