Answer:

The freezing point depression ∆T = KF·m where KF is the molal freezing point depression constant and m is the molality of the solute. Rearrangement gives: mol solute = (m) x (kg solvent) where kg of solvent is the mass of the solvent (lauric acid) in the mixture. This gives the moles of the solute.

Answer:

A. The atoms have more energy together than separated.

Explanation:

There are several reasons why a chemical bond could take place. Adding things like heat or pressure stimulate the atoms to force a reaction to take place. But when it comes down to it, the intramolecular forces of the electrons  pull each other to form chemical bonds (represented by Valence electrons). The stronger these are, the more likely they are going to bond.

Atoms with lower forces typically don't typically bond with other atoms of lower forces.

Answer:

Molarity of solution = 0.77 (Approx.)

Explanation:

Given:

Moles of LiCl = 0.529

Volume of water  = 687

Find:

Molarity of solution

Computation:

Molarity of solution = [Moles/Volume]1000

Molarity of solution = [0.529/687]1000

Molarity of solution = 0.77 (Approx.)

Explanation:

Answer:

410 nm

Explanation:

when an electron falls from ni=6 to nf=2 , a photon of wavelength 410 nm is emitted.

When an electron falls then the wavelength of the electromagnetic radiation emitted is = 410 nm.

When The Electromagnetic wavelength directs to the measured distance between the trough or crest of each adjacent wave generated by the electromagnetic disturbance.

When the wavelength of electromagnetic radiation is comparable to the de Broglie wavelength of its quantum (photon).

Now we are Showing that the wavelength of electromagnetic radiation is comparable to the de Broglie wavelength of its quantum (photon).

Therefore, when an electron falls from ni=6 to nf=2, a photon of wavelength 410 nm is emitted.

Answer:

Particles?  Calcium hydroxide does not exist as discrete molecules, but as a network solid.  The only way you would have separate particles, is if the calcium hydroxide was dissolved in a boatload of water.  Ca(OH)2 is not all that soluble in water.  Nonetheless, assume a lot of water, enough to dissolve 56.9 moles.

Ca(OH)2 --> Ca2+ + 2OH-

56.9 moles Ca(OH)3 x (3 moles ions / 1 mol Ca(OH)2) = 170.7 mol ions

Answer:

False

Explanation:

Non- metals tend to gain electrons easily, metals tend to lose electrons easily

For example, oxygen, a non-gas, when it is an ion, has the option to lose 6 electrons to become like helium, or gain 2 electrons to become like the noble gas neon. However, it becomes like neon for 2 reasons.

A. As a general rule, atoms lose/gain the LEAST amount of electrons.

B. Oxygen is a nonmetal, therefore, to become like a Noble Gas, it would gain, as non-metals usually would, 2 electrons.

Radiant energy to chemical energy

Explanation:

Got it right on edge 2021

One energy transformation that is taking place in the photosynthesis process is radiant energy to chemical energy.

Energy transformation is the process in which one form of energy converted into another form of energy.

Photosynthesis process is defined as the process in which plants makes their own food by using the carbon dioxide, water and sunlight in the chlorophyll.

The balanced chemical equation of photosynthesis process is

6CO2 + 6H2O → C6H12O6 + 6O2.

Since, it have 6 atoms of carbon, 12 atoms of hydrogen and 18 atoms of oxygen on both side. So, it is balanced.

Since, sunlight which it take is in the form of radiant and convert it into chemical energy.

Thus, we concluded that the energy transformation that is taking place in the photosynthesis process is radiant energy to chemical energy.

The elements shown have an atomic mass of 20 amu is Neon.

The atomic number of an atom is its total number of protons and neutrons.

Neon has an atomic mass of about 20 this isotope contains 10 protons and 10 neutrons.

Actually, Neon would be listed as having an atomic mass of about 20.18 because of a mixture of isotopes.

Z= Atomic number the number of protons in the nucleus which defines the element.

In this case,  Z=10 and this means neon but there are also 10 neurons in the nucleus of the major isotope which gives it 20Ne.

Hence, option D is the correct answer.
