In which state of matter are molecules moving the slowest?.

The word or two-word phrase that best describes the shape of the phosgene molecule is "V-shaped" or "bent."

Phosgene is a harmful gas that was first used as a chemical weapon during World War I. It has a pale yellowish color and a slightly unpleasant odor. It is a covalent compound made up of carbon, oxygen, and chlorine atoms, with the molecular formula COCl2. It has a V-shaped or bent molecular shape because of its two lone pairs of electrons on the central atom that repel the bonded pairs and pushes them away from each other, resulting in a bent shape. Therefore, "V-shaped" or "bent" is the word or two-word phrase that best describes the shape of the phosgene molecule.

Option (c) is correct. The Hydrogen bond makes the water liquid at room temperature.

The hydrogen bond in water is covalently bonded to the central oxygen atom by a pair of electrons that are shared between them. In water, only two of the six outer-shell electrons of oxygen are used for the purpose of leaving four electrons which are organized into two non-bonding pairs. The four electron pairs surrounded the oxygen tend to arrange themselves as far from each other as possible in order to minimize repulsions between these clouds of negative charge in the water. The water molecule is electrically neutral. The positive and negative charges are not distributed uniformly in water.

Answer:

atom

Explanation:

This describes an ATOM

This is a microscope.

Hope this clears that up for you.

This is because the bond angle is determined by the number of lone pairs and bonded atoms around the central atom. The correct answer is (2) OF2 < SnF2 < XeF2.

Oxygen in OF2 has 2 lone pairs and 2 bonded atoms, resulting in a smaller bond angle than the other two molecules. Tin in SnF2 has 2 lone pairs and 2 bonded atoms as well, but its larger size allows for a larger bond angle than OF2. Finally, xenon in XeF2 has 3 lone pairs and 2 bonded atoms, resulting in the largest bond angle among the three molecules.
The molecules in order of increasing bond angles. Based on the given options, the correct order is:
(3) SnF2 < OF2 < XeF2
1. SnF2 has a bent molecular geometry with a bond angle of less than 109.5° due to the influence of the lone pair on the Sn atom.
2. OF2 has a bent molecular geometry as well, but with a bond angle of approximately 109.5° because of the two lone pairs on the O atom and the strong electronegativity of the O atom.
3. XeF2 has a linear molecular geometry with a bond angle of 180° due to the presence of three lone pairs on the Xe atom.
So, the order of increasing bond angles is SnF2 < OF2 < XeF2.

Answer:

Conditions which results in deviating a gas from "ideal" behavior are

1. Low Temperature

2. High Temperature

Explanation:

Ideal gas according to the kinetic model theory states that the conditions that apply are high temperatures where kinetic energy and low pressure is too high and the interactions in between and the container are negligible. Hence, the deviations of ideal gas falls when there is low temperature and high pressure.

It will take 11.1 hours for 8.40 g of the iodine-123 sample to decay.

The decay of iodine-123 is a first-order process, meaning that the rate of decay is proportional to the amount of iodine-123 present. The half-life of iodine-123 is 13.1 hours, which means that half of the original sample will decay in that time.

To calculate the time it will take for 8.40 g of the sample to decay, we can use the following formula for first-order decay:

where Nt is the amount remaining at time t, N0 is the initial amount, k is the rate constant, and t is the time.

We can rearrange this formula to solve for t:

We know that Nt/N0 = 8.40 g / 10.00 g = 0.84, and we can calculate k from the half-life:

Plugging these values into the formula for t, we get:

Therefore, it will take 11.1 hours for 8.40 g of the iodine-123 sample to decay.

Answer:

469.9K

Explanation:

Using Charles's law equation:

V1/T1 = V2/T2

Where;

V1 = initial volume (ml)

V2 = final volume (ml)

T1 = initial temperature (K)

T2 = final temperature (K)

Based on the information provided:

V1 = 280.0ml

V2 = 440.0 ml

T1 = 26.0°C = 26 + 273 = 299K

T2 = ?

Using V1/T1 = V2/T2

280/299 = 440/T2

0.936 = 440/T2

T2 = 440 ÷ 0.936

T2 = 469.9K

Explanation:

The pairs of conditions that need to construct a similar cell that generates the lowest cell potential is [Zn2+]=0.5M and [Fe2+]=1M because Q<1. The correct answer is option A,

In order to construct a similar cell that generates the lowest cell potential, we need to consider the Nernst equation.

Where,

Ecell=E°cell − (0.0592/n) log Q

Where,

E°cell = Standard electrode potential

n = Number of electrons exchanged

Q = Reaction Quotient = [products]/[reactants]

For the given reaction, the cell potential is +0.32 V. This implies that under standard conditions, Q = 1.The answer to the given question is that [Zn2+] = 0.5 M and [Fe2+] = 1 M because Q < 1.

The conditions under which the standard electrode potential of a half-cell is measured are referred to as standard conditions. This usually entails a concentration of 1.00 mol/L for all substances, an atmospheric pressure of 1.00 atm, and a temperature of 25°C.

Answer:

Explanation:

The sign of q for this process is negative as heat is released into the surroundings when a sample of explosive TNT is detonated under atmospheric pressure.

When TNT(Trinitrotoluene) is detonated under atmospheric pressure, it undergoes an exothermic reaction which releases a large amount of heat and gas. This process is highly exothermic and releases energy in the form of heat, light, and a shock wave. The force exerted by the air on the surface above it is called Atmosphere Pressure. Atmospheric pressure is measured using a device called barometer. The standard atmosphere is a unit of pressure given by 101,325 Pa, which is equivalent to 1013.25 millibars, 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.

Hence, if a system's entropy S increases, its thermodynamic probability W must do likewise. The fact that W always rises in a spontaneous change, also means that S must rise in the same change.

By definition, and this is what Avogadro's constant tells you, 1 mole of nickel must contain 6.022⋅1023 atoms of nickel.

Explanation:

No, the source is not usable. It is barely usable taking into account it's half life.

The period of time it takes for one-half of a radioactive isotope to decay is known as the half-life. An individual radioactive isotope's half-life is unaffected by environmental factors and is independent of the isotope's starting concentration. A substance's activity is a thermodynamic characteristic connected to its chemical potential. Chemical potentials are less practical to employ than activities, which are more closely tied to concentration measurements like partial pressures and mole fractions.

The activity is

\(\frac{dN}{dt} =\) λN

Therefore

N= \(N_{o} 2^{-\frac{t}{T_{0.5} } }\)

The amount of elapsed time since the source was created is roughly 2.5 years. Thus, we expect the current activity to be after calculating and using values,
