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.
Have a nice day!
Answer:
Highest temperature which was recorded in Texas was 40 degrees.
Explanation:
Texas has variating weather. In summer Texas city turns to be very hot and during winters the city of Texas experience fall in temperature. There is very few rainfall in Texas due the climatic conditions.

Answer:pure water is neutral . Lake water is acidic. Baking soda and soapy water are basic.
Explanation: 7 is neutral. The higher on the ph scale like 1-6 is acidic. The lower on the scale 8-13 is base or alkaline.
Answer : The mass percentage of isopropyl alcohol in the solution is, 59.4 %
Explanation :
To calculate the mass percentage of isopropyl alcohol in the solution, we use the equation:
Mass of isopropyl alcohol = 6.68 g
Mass of isopropyl alcohol solution = 3.97 g
Putting values in above equation, we get:
Thus, the mass percentage of isopropyl alcohol in the solution is, 59.4 %
