How much salt (NaCl) is carried by a river flowing at 30.0 m3/s and containing 50.0 mg/L of salt
denis23 [38]

Answer:

129,600kg/day

Explanation:

The river is flowing at 30.0

1 m³ is equivalent to 1000L

flowrate of river = 30*1000 =30,000L/s

Convert L/s to litre per day by multiplying by 24*60*60

flowrate of river = 30,000 * 24*60*60 L/day

                    = 2,592,000,000L/day

if the river contains 50mg of salt  in 1L of solution

lets find how many mg of salt Y is contained in 2,592,000,000L/day

by cross multiplying we have

Y=\frac{2592000000*50}{1}

Y= 129,600,000,000 mg/day

convert this value to kg/day by dividing by 1 million

Y= 129,600,000,000/1000000

Y= 129,600kg/day

A chemical reaction is at equilibrium. what will be the effect if more of the product is added? question 10 options: the reactio
VashaNatasha [74]

The answer is <span>the reaction will shift to the left (toward the reactants).

Reaction is at equilibrium can be expressed as,
      Reactants </span>⇄ products<span>

<span>After coming to the equilibrium, if one condition is changed, then according to the </span>Le chatelier's Principal,<span> the system will act to maintain the equilibrium by reducing the effect. As an example, if we reduce the pressure, then system acts to increase the pressure to maintain the equilibrium.</span>

<span>Likewise, if we add products into the reaction which is in equilibrium, the system acts to reduce the effect by promoting the backward reaction to produce reactants.</span></span>

Make a conclusion about the following question: What is the relationship between the volume of a gas and the pressure exerted on
Alinara [238K]

The relationship would be inversely proportional, meaning that as the volume increases, the pressure decreases, and the opposite is true as well, as the pressure increases, the volume decreases.
