Explanation:
Intravenous (IV) tubing or valves can prevent back flow and contamination of injection devices. This is also false! The truth is that everything from the syringe or medication bag to the patient's IV catheter is a single interconnected unit.
Answer:
201 countries
Explanation:
There are 195 countries in the World, 54 countries is Africa, which is 249 countries. Then 48 countries is Asia, so 201 countries.
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:
Ksp = 1.8 × 10⁻¹⁰
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}}](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%20%5BAg%28NH_3%29_2%5E%7B%2B%7D%5D%5BCl%5D%7D%7B%5BNH_3%5D%5E2%7D%5C%5C%5C%5C3.06%20%5Ctimes%2010%5E%7B-3%7D%3D%5Cfrac%7B%5Bx%5D%5Bx%5D%7D%7B0.50%5E%7B2%20%7D%7D%5C%5C%5C%5C3.06%20%5Ctimes%2010%5E%7B-3%7D%3D%5Cfrac%7Bx%5E2%7D%7B0.25%7D%5C%5C%5C%5Cx%5E2%20%3D%207.65%5Ctimes%2010%5E%7B-4%7D%5C%5C%5C%5Cx%3D%5Csqrt%7B7.65%5Ctimes%2010%5E%7B-4%7D%7D)
x = 2.77 × 10⁻² M.
