Answer:
The particles move faster and are far apart
Explanation:
A substance may exist in three states of matter; solid, liquid and gas.
In the solid state, there is very strong intermolecular forces between the particles of the substance. They can only vibrate or rotate about their mean positions but can not translate.
In the liquid state, the particles of the substance have a greater degree of freedom than in the solid. The magnitude of intermolecular forces is lower than in solids, the molecules can move at low speeds.
In a gas, the molecules are separated from each other with negligible intermolecular interaction hence they move at very high speed.
Therefore, for the water gas particles in the air above the cup; the particles move faster and are far apart.
The formal charge in the central metal atom Nitrogen atom is O.
Structure O=N=f formal charge on N = 0
Formal charge in a Lewis shape, for every atom, you need to count how many electrons. count number all of its lone pair electrons, and 1/2 of its bonding electrons. The difference among the atom's range of valence electrons and the range it owns is the formal rate
Nitrosyl fluoride is used as a solvent and as a fluorinating and nitrating agent in natural synthesis. It has additionally been proposed as an oxidizer in rocket propellants.
The guideline or method for assigning formal rate to atoms in Lewis systems is the subsequent: Formal fee = number of valence electrons - variety of lone-pair electrons + 1/2 range of bonding electrons.

Answer:
A vase on a table overcomes gravity because of the upwards force of the table against it, which is stronger than the force of gravity. If you were to move the vase off the table it would no longer have anything stopping gravity from breaking it.
Explanation:
Answer: 80 ml
Explanation:
V= vol ml, C = concentration %
V1 = 20ml, C1 = 20%
V2 = ? , C2 = 5%
V1C1 = V2C2
V2 = (V1C1)/C2
V2 = (20ml x 20%) / 5% = 80 ml
Answer:
6.1×10^4Pa or 61KPa
Explanation:
The Clausius-Clapeyron equation is used to estimate the vapour pressure at different temperature, once the enthalpy of vaporization and the vapor pressure at another temperature is given in the question. The detailed solution is shown in the image attached. The temperatures were converted to kelvin and the energy value was converted from kilojoule to joule since the value of the gas constant was given in unit of joule per mole per kelvin. The fact that lnx=2.303logx was also applied in the solution.
