Answer:
the product and the reactant must be balanced
if u are required to give the mechanism if the reaction it must be written
Answer:
a) 64.27%
b) 58%
c) ethanol is the limiting reactant
d) ethanol is the limiting reactant
Explanation:
We have to note that the expected yield is the theoretical yield while the actual mass or amount of product formed is the actual yield.
a) theoretical yield=68.3g
Actual yield= 43.9 g
Percentage yield= 43.9/68.3 ×100
Percentage yield= 64.27%
b) theoretical yield= 0.0722 moles
Actual yield = 0.0419
Percentage yield= 0.0419/0.0722 × 100
Percentage yield= 58%
c) note that the limiting reactant yields the least number of moles of product
Ethanol will be the limiting reactant since it is not present in excess.
d) from the reaction equation;
1 mole of acetic acid produces 1 mole of ethyl acetate
0.58 moles of ethanol produces 0.58 moles of ethyl acetate
1 mole of acetic acid yields 1 mole of ethyl acetate
Hence 0.82 moles of acetic acid yields 0.82 moles of ethyl acetate
Hence ethanol is the limiting reactant.
We imagine a piston cylinder and a solution of gas and water. Molecules are in constant random motion and some of the gas particles are in the vapor phase while some in the liquid phase. At a specific volume, molecules move freely. However, when the piston is moved down, increasing the pressure, some of the molecules in the vapor are pushed down to the liquid phase in order maintain equilibrium thus increasing solubility <span />
Answer:
A particle is the smallest possible piece of something, of matter, while a molecule is the smallest particle of an element, for example H2 is molecule, smallest particle of the hydrogen in the air, and the molecule is two or more atoms held with chemical bonds, and have chemical properties.
The number of sandwiches that can made with 6 pieces of bread and 4 slices of cheese is 3 sandwiches.
<h3>What are limiting reactants?</h3>
Limiting reactants are those reactants which determine the amount of product that can be formed since they get used up in a reaction.
In the making of sandwiches from bread and cheese, the limiting reactant is the material that is used up.
The formula for making a sandwich is given below;
2 pieces of bread + 1 slice of cheese = 1 sandwich
6 pieces of bread can make 3 sandwiches
4 slices of cheese can make 4 sandwiches
Thus, bread is the limiting reactant.
Therefore, the number of sandwiches that can made with 6 pieces of bread and 4 slices of cheese is 3 sandwiches.
