Answer: The correct answer is all of the above.

Explanation:

Volume is defined as the amount of space that a substance is occupying. The S.I. unit of this property is Liter (L).

There are 3 states of matter:

Solid state: In this state, the particles of the state are orderly arranged and it occupies specific shape and volume.
Liquid state: In this state, the particles of the state are not orderly arranged and it occupies the shape and volume of the container.
Gaseous state: In this state, the particles are randomly arranged and the particles occupies the shape and volume of the container in which it is kept.

Hence, the volume is occupied by all the three states.

Thus, the correct answer is all of the above.

Give an example of how a functional group can affect the properties of an organic compound.

Svetradugi [14.3K]

The functional group can affect the chemical properties and physical properties. Like CH3CH3 and CH3CH2OH. The first one is gas and second one is liquid. The first one is not easy to react with others while the second one is.

The following anions can be separated by precipitation as silver salts: Cl- , Br- , I- , CrO4 2-. If Ag is added to a solution c

dalvyx [7]

Answer:

AgI, AgBr, AgCl and Ag₂CrO₄

Explanation:

Ksp (product solubility constant) is defined as the equilibrium constant of the general reaction:

XₐYₙ(s) → aXⁿ⁺(aq) + nYᵃ⁻(aq)

Where X is cation and Y is anion.

Ksp = [aXⁿ⁺]ᵃ [nYᵃ⁻]ⁿ

The presence of XₐYₙ(s) produce ax moles of aXⁿ⁺ and nx moles of Yᵃ⁻. Where X is the solubility of the compound.

Replacing in Ksp:

Ksp = [ax]ᵃ [nx]ⁿ

Solving for x, Solubility (S) is defined as:

$S = \sqrt[n+a]{\frac{Ksp}{a^{a} n^n} }$

For AgCl, Ag₂CrO₄, AgBr and AgI solubilities are:

$S = \sqrt[2]{\frac{1.8x10^{-10}}{1} }$ = 1.34x10⁻⁵M

$S = \sqrt[3]{\frac{1.1x10^{-12}}{4} }$ = 6.50x10⁻⁵M

$S = \sqrt[2]{\frac{5.4x10^{-13}}{1} }$ = 7.35x10⁻⁷M

$S = \sqrt[2]{\frac{8.5^{-17}}{1} }$ = 9.22x10⁻⁹M

The lower solubility is the first compound in precipitate, thus, order of precipitation is:

AgI, AgBr, AgCl and Ag₂CrO₄

At 3 atm pressure the volume of gas is 1200ml. What pressure is required to reduce the volume of the gas to 300ml if the tempera

Rufina [12.5K]

States that when a gas is held at a constant temperature and mass in a closed container, the volume and pressure vary inversely. The equation to use is P1V1=P2V2.

Given
V1=200mL×1L1000mL=0.2 L
P1=700 mmHg
V2=100mL×1L1000mL=0.1 L

Unknown
P2

Equation
P1V1=P2V2

Solution
Rearrange the equation to isolate P2 and solve.

P2=P1V1V2

P2=(700mmHg×0.2L)0.1L=1400 L, which must be rounded to 1000 L because all of the measurements have only one significant figure.
