The answer is option D "they are vibrating slightly." In ice the molecules are stuck together and shaking like a bunch of little people together trying to keep warm. Also its not option C because they do move all four stages move. (solid, liquid, gas, plasma) Its not option B Liquid molecules are slowly moving around therefore those molecules are moving faster than a solid. Its also not option A because as discussed solids move slower than a liquid.

Hope this helps!

They are vibrating slightly.

It is know to us that when a matter is cooled down, it's motion of molecules decreases relatively. And on the other hand, when a matter is heated, it's molecular motion increases and thus produced Kinetic Energy is converted into heat energy and hence increasing the temperature of the matter. So, when water is cooled and it changes it's state from liquid to ice, it's molecular motion is very slow.

The following equations are half reactions and reduction potentials. Ag+ (aq) + e– Ag(s) has a reduction potential of +0.80 V. C
Lady bird [3.3K]

Answer : The correct option is, (A) silver ion gains electrons more easily and is a stronger oxidizing agent than a chromium(III) ion.

Explanation :

The given half reaction are :

1st half reaction : Ag^+(aq)+e^-\rightarrow Ag(s)

The reduction potential of this reaction = +0.80 V

2nd half reaction : Cr^{3}+(aq)+3e^-\rightarrow Cr(s)

The reduction potential of this reaction = -0.74 V

From the reduction potentials, we conclude that the reaction which have positive reduction potential, they will gain electrons more easily and reduced itself and act as a stronger oxidizing agent.

Or we can say that the reaction which have negative reduction potential, they will lose electrons more easily and oxidized itself and act as a stronger reducing agent.

The reduction potential of 1st half reaction is positive and 2nd half reaction is negative.

Therefore, the silver ion gains electrons more easily and is a stronger oxidizing agent than a chromium(III) ion.

Which property or properties can change when the pressure of a gas changes?
inn [45]

Answer: This law states that the volume and temperature of a gas have a direct relationship: As temperature increases, volume increases, when pressure is held constant. Heating a gas increases the kinetic energy of the particles, causing the gas to expand

for number less than 0.1, such as 0.06, the zeros to the right of the decimal point but before the first nonzero digit
qaws [65]

For the number less than 0.1 such as 0.006, the zeroes to the right of the decimal point but before the first non zero digit show the decimal place of the first significant digit.

  • The number that is given as digits is established using significant figures.
  • Any two non-zero digits that are separated by a zero are significant figure.
  • Every zero that is both to the right and left of a non-zero digit and the decimal point is not significant figure.
  • The quantity of significant figures frequently reveals the degree of measurement accuracy. From the first non-zero digits in the figure, we may determine the number of significant figures.

There is only one significant figure in the provided number 0.06. The decimal place of the first digit is indicated by the zeros that appear to the right of the decimal point but before the first non-zero digit.

Atoms bond in several different ways to form molecules. Which changes result from an ionic bond between two atoms?
-BARSIC- [3]
C. Electrons move from the electron shell of 1 atom to the electron shell of another atom.

A is incorrect as 1 atom loses electrons while the other gains. B is incorrect as electrons are not stored in or transferred between nuclei. D is wrong as it is the definition of a covalent bond, not an ionic bond.
