Answer: 1.037M
Explanation:
Since the rate constant unit is per seconds, therefore it is a first order reaction.
First order reaction equation is given as
InA= -kt +InAo
Where,Ao is the initial concentration of reactant =0.600M
A is the concentration of reactant at a specifies time t=3×60=180s
and k is the rate constant
InA = -6.50×10^-3 ×180 +In(0.6)
InA = -1.17 + 0.5108
InA= -1.680
A = e-1.680
A= 1.037M
Therefore the concentration after 3minutes is 1.037M
The event is South American independence. <u>Option D.</u>
<u />
By 1820, royalist Peru was an isolated outpost of Spanish influence. San Martin liberated Chile and Argentina to the south while Simon Bolivar and Antonio Jose de Sucre liberated Ecuador Colombia, and Venezuela to the north leaving only Peru and present-day Bolivia under Spanish control.
Simon Bolivar wrote two of his political treatises. The Manifesto de Cartagena Declaration of Cartagena and Carta de Jamaica Letters from Jamaica told the people of South America that Spain urged them to rebel against their colonial rule. Simon Bolivar is a Creole who grew up in a wealthy family. Bolivar devoted his time and effort to fight for Venezuela's independence from Spain. Bolivar was inspired by the Enlightenment ideas of John Locke.

Hello!
1) What is the limiting reactant?The chemical equation for the reaction is the following:
Fe + S → FeS
To determine the limiting reactant, we will determine the
moles of each reactant and divide it by the coefficient in the chemical equation (In this case is I for each one)
Now, the reactant with the less number of moles is Fe, so
Fe is the limiting reactant.
2) The reactant in excess.
From the chemical reaction:
Fe + S → FeS
The reactant in excess is the one that is in the
highest amount. To determine which is the reactant in excess we need to calculate the moles of each reactant and divide by the coefficient in the chemical reaction:
The reactant in excess is S, the amount that is left after the reaction is:
So there are
0,2679 moles of S in excess after the reaction.
3)
What mass of FeS is created?To determine the mass of FeS created we need to go from moles of Fe (Limiting reactant) to grams of FeS (Product) using the following conversion factor:
So,
23,99 grams of FeS are produced from this chemical reaction.
