The actual value is greater than the theoretical value
<h3>Further explanation</h3>
Given
Reaction
Sb2S3 + 3Fe --> 2Sb + 3FeS
0.022 mol Sb2S3
0.08mol Sb
Required
The percent yield
Solution
Percent yield is the comparison of the amount of product obtained from a reaction(actual) with the amount you calculated
(theoretical)
General formula:
Percent yield = (Actual yield / theoretical yield )x 100%
Theoretical yield of Sb : 2/1 x 0.022 mol = 0.044 moles
In the question, there seems to be an error, because the actual yield value(0.08=?) should be smaller than the theoretical yield(0.044)
Answer : The complete chemical equation is,
Explanation :
As we know that, in a chemical equation the reacting species present on left side and the product formed present on right side and a right arrow inserted between the reactants and product that show a chemical reaction taking place.
In the chemical reaction, the phases of the substances are also included and subscripts and superscripts are also used for the numbers.
For the given chemical reaction, the balanced chemical equation including the phases, is given by:
Answer:
Because of time zones?
Explanation: The only thing that would make sense to me is the time zones.
The product of a reaction between these two elements is .
Explanation:
The oxidation state of an ion in a compound is equal to its charge.
The aluminum having a charge of +3 because oxidation state is +3
The oxide is having charge of -2
The product of these reactants will produce a chemical compound.
The compound formed is i.e Aluminium oxide. The compound while getting formed will share the charge and cation A+ will have the charge of anion and anion will have the charge of cation. This will result in a compound as there should be a neutral charge on the compound formed.
The <em>+</em><em>3 charge of the cation Al+ will go to anion oxide O2- and the charge of anion -2 will go with cation Al+. </em>

Answer:
Explanation:
The expression for the root mean square speed is:
R is Gas constant having value = 8.314 J / K mol
M is the molar mass of gas
Molar mass of = 0.04599 kg/mol
Temperature = 400 K
Thus,
