Answer: gravity

Explanation:

Mass movement or mass wasting is a natural process in which the unstable sediments, stones, pebbles, debris moves down the slope under the effect of gravity. These materials are disturbed by physical agents such as water, wind and others. The mass movement is responsible for mudslides or landslides.

The theoretical yield of H₂S is 13.5 g.

The percent yield is 75.5 %.

<h3>What is the theoretical yield of H₂S from the reaction?</h3>

The equation of the reaction is given below:

  • FeS + 2 HCl → FeCl₂+ H₂S

Moles of FeS reacting = mass/molar mass

Molar mass of FeS = 88 g/mol

Moles of FeS reacting = 35/88 = 0.398 moles

Moles of H₂S produced = 0.398 moles

Molar mass of H₂S = 34 g/mol

Mass of H₂S produced = 0.398 * 34 = 13.5 g

Theoretical yield of H₂S is 13.5 g.

  • Percent yield = actual yield/theoretical yield * 100%

Actual yield of H₂S = 10.2 g

Percent yield = 10.2/13.5 * 100%

Percent yield = 75.5 %

In conclusion, the actual yield is less than the theoretical yield.

Alexus [3.1K]

Answer: The rate law is rate=k[CH_3COOC_2H_5]^1[NaOH]^1

Explanation:

Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.

For the given reaction:

CH_3COOC_2H_5(aq)+NaOH(aq)\rightleftharpoons CH_3COONa(aq)+C_2H_5OH(aq)

k= rate constant

Rate law: rate=k[CH_3COOC_2H_5]^x[NaOH]^y

For the given rate law:

y =1 =  order with respect to NaOH

n = total order = 2

2= (x+y)

2= (x+1)

x= 1

Thus order with respect to CH_3COOC_2H_5 is 1 and rate law is : rate=k[CH_3COOC_2H_5]^1[NaOH]^1
