Answer:
It is called Potassium Hydroxide
Answer:-
0.229 L
Explanation:-
Molar mass of AgBr = 107.87 x 1 + 79.9 x 1
=187.77 grams mol-1
Mass of AgBr = 150 grams
Number of moles of AgBr = 150 grams / 187.77 gram mol-1
= 0.8 mol
The balanced chemical equation is
NaBr (aq) + AgNO3 (aq)--> AgBr(s) + NaNO3(aq)
From the equation we can see that
1 mol of AgBr is produced from 1 mol of AgNO3.
∴ 0.8 mol of AgBr is produced from 1 x 0.8 / 1 = 0.8 mol of AgNO3.
Strength of AgNO3 = 3.5 M
Volume of AgNO3 required = Number of moles / strength
= 0.8 moles / 3.5
=0.229 L
Ksp of PbBr₂ is 6.60 × 10⁻⁶. The molar solubility of PbBr₂ in pure water is 0.0118M.
Ksp or Solubility Product Constant is an equilibrium constant for the dissociation in an aqueous solution.
Molar solubility (S) is the concentration of the dissolved substance in a solution that is saturated.
Let the molar solubility be S upon dissociation.
PbBr₂ or Lead Bromide dissociates in pure water as follows:
PbBr₂ ----------> Pb⁺² + Br⁻
S 2S
Ksp = [Pb⁺²] [ Br⁻]
Ksp = (S) (2S)²
Ksp = 4S³
6.60 × 10⁻⁶ = 4S³
S = 0.0118M
Hence, the Molar solubility S is 0.0118M.

Answer:
a) 213.3 mg/L
b) 62.61 mg/L
c) 0.0225 mg/L
Explanation:
Theoretical oxygen demand (ThOD)is essentially the amount of oxygen required for the complete degradation of a given compound into the final oxidized products
a) Given:
Concentration of acetic acid,![[CH3COOH]](https://tex.z-dn.net/?f=%5BCH3COOH%5D)
= 200 mg/L
Based on the reaction stoichiometry:
mass of 
= 60 g
mass of 
= 2(32) = 64 g
b) Given:
Concentration of ethanol, ![[C2H5OH]](https://tex.z-dn.net/?f=%5BC2H5OH%5D)
= 30 mg/L
Based on the reaction stoichiometry:
mass of 
= 46 g
mass of = 3(32) = 96 g
c) Given:
Concentration of sucrose, ![[C12H22O11]](https://tex.z-dn.net/?f=%5BC12H22O11%5D)
= 50 mg/L
Based on the reaction stoichiometry:
mass of 
= 342 g
mass of = 12(32) = 384 g
I think the correct answer from the choices listed above is the first option. When the the pressure is increased, the equilibrium of the reaction would favor <span>formation of reactants. One indication would be the gas that is present in the product side. Increasing the pressure would allow the products to react and form the reactants. Hope this helps.</span>
