There are multiple theories out there on how the universe came to be.
There is one scientifical theory out there that everybody knows. They think the universe was created by the Big Bang Theory. Or the universe was created by hydrogen, helium, and baryonic matter.

Hope this helped :)
Have a great day

The graph of the function f is the graph of the function g compressed horizontally by a factor of 2 and shifted to the right by
Alecsey [184]

Answer: A) f(x) = g(2x - 1)

Explanation:

<u>Original function = g(x)</u>

  • Compress g(x) horizontally by 2 = g(2x)
  • Shift to the right by 1 = g(2x -1)

What is the molar solubility of agcl (ksp = 1. 80 × 10⁻¹⁰) in 0. 500 m nh₃? (kf of ag(nh₃)₂⁺ is 1. 7 × 10⁷)
Hoochie [10]

Based on the calculations, the molar solubility of AgCl in 0. 500 M of NH₃ is equal to 2.77 × 10⁻² M.

<u>Given the following data:</u>

  • Ksp of mg(oh)₂ = 1.8 × 10⁻¹⁰
  • Concentration of NH₃ = 0.500
  • Kf of ag(nh₃)₂⁺ = 1.7 × 10⁷

<h3>How to determine the molar solubility.</h3>

First of al, we would write the properly balanced chemical equation for this chemical reaction:

                          AgCl(s)\rightleftharpoons Ag^{+} (aq)+ Cl^{-}(aq)       Ksp = 1.8 × 10⁻¹⁰

                AgCl(s) + 2NH_3(aq)\rightleftharpoons  Ag(NH_3)_2^{+}(aq)   Kf = 1. 7 × 10⁷

K = Ksp × Kf

K = 1. 80 × 10⁻¹⁰ × 1.7 × 10⁷

K = 3.06 × 10⁻³

Mathematically, the Ksp for the above chemical reaction is given by:

K=\frac{ [Ag(NH_3)_2^{+}][Cl]}{[NH_3]^2}\\\\3.06 \times 10^{-3}=\frac{[x][x]}{0.50^{2 }}\\\\3.06 \times 10^{-3}=\frac{x^2}{0.25}\\\\x^2 = 7.65\times 10^{-4}\\\\x=\sqrt{7.65\times 10^{-4}}

x = 2.77 × 10⁻² M.
