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)

<em>Where X is cation and Y is anion.</em>

Ksp = [aXⁿ⁺]ᵃ [nYᵃ⁻]ⁿ

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

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:

<em>AgI, AgBr, AgCl and Ag₂CrO₄</em>

How are half life and radioactive decay related
hoa [83]

Answer : Half life and radioactive decay are inversely proportional to each other.

Explanation :

The mathematic relationship between the half-life and radioactive decay :

N=N_oe^{-\lambda t}              ................(1)

where,

N = number of radioactive atoms at time, t

N_o = number of radioactive atoms at the beginning when time is zero

e = Euler's constant = 2.17828

t = time

\lambda = decay rate

when t=t_{1/2} then the number of radioactive decay become half of the initial decay atom i.e N=\frac{N_o}{2}.

Now substituting these conditions in above equation (1), we get

\frac{N_o}{2}=N_oe^{-\lambda t_{1/2}}

By rearranging the terms, we get

\frac{1}{2}=e^{-\lambda t_{1/2}}

Now taking natural log on both side,

ln(\frac{1}{2})=-\lambda \times t_{1/2}

By rearranging the terms, we get

t_{1/2}=\frac{0.693}{\lambda}

This is the relationship between the half-life and radioactive decay.

Hence, from this we conclude that the Half life and radioactive decay are inversely proportional to each other. That means faster the decay, shorter the half-life.
