Acid rain is caused by both natural sources and man-made sources. Natural sources like volcanic eruptions, decaying vegetation, sulfur dioxide gases, and nitrogen oxide gases can mix with water, oxygen and sunlight in the atmosphere that can then cause acid rain. Man made resources are from fossil fuel combustion.

According to the phase diagram for water, how is the state of water determined?

joja [24]

Explanation:

From the attached phase diagram, one can easily make out the phase in which water exists. Matter generally exists in three physical states which are solid, liquid and gas. Water is a unique compound that can exists in these three states at a given temperature and pressure.

From the attached phase diagram,

point O is the triple point where the three phases of pure substance co-exists.
The areas between the curves points at a single phase of matter. Y is a water vapor.
The lines on the curve denotes two equilibrium phases. For example; X is a phase contain ice and melt water.

For the reaction ag2s(s) ⇌ 2 ag+ (aq) + s2- (aq), keq = 2.4 × 10-4 and the equilibrium concentration of silver ion is [ag+] = 2.

Juliette [100K]

Answer : The concentration of silver ion is, $3.8\times 10^{-3}M$

Explanation :

Equilibrium constant : It is defined as the equilibrium constant. It is defined as the ratio of concentration of products to the concentration of reactants.

The equilibrium expression for the reaction is determined by multiplying the concentrations of products and divided by the concentrations of the reactants and each concentration is raised to the power that is equal to the coefficient in the balanced reaction.

As we know that the concentrations of pure solids and liquids are constant that is they do not change. Thus, they are not included in the equilibrium expression.

The given equilibrium reaction is,

$Ag_2S(s)\rightleftharpoons 2Ag^+(aq)+S^{2-}(aq)$

The expression of $K$ will be,

$K_{eq}=[Ag^+]^2[S^{2-}]$

$2.4\times 10^{-4}=(2.5\times 110^{-1})^2[S^{2-}]$

$[S^{2-}]=3.8\times 10^{-3}M$

Therefore, the concentration of silver ion is, $3.8\times 10^{-3}M$

The reaction 2no2 ? 2no + o2 follows second-order kinetics. at 300 °c, [no2] drops from 0.0100 m to 0.00650 m in 100.0 s. the ra

Ulleksa [173]

For a second order kinetics, the reaction rate expression would be

-r = -dCa / dt = kCa^2 where k is the reaction constant and Ca is the concentration of reactant A.

Integrating this from Cao to Caf, will have the expression,

1/Caf - 1/Cao = kt

Substituting the given values and calculating for k,

1/0.00650 - 1/0.0100 = k(100)
k = 0.538 / M-s
