Moles of Fe2O3 used : 3.83

<h3>Further explanation</h3>

Given

11.5 moles of CO2

Required

moles of Fe2O3

Solution

Reaction

Fe2O3 + 3CO ⇒2Fe + 3CO2

The reaction coefficient shows the mole ratio of the reacting compound (reactants or products)

From the equation, mol ratio of Fe2O3 : CO2 = 1 : 3, so mol Fe2O3 :

= 1/3 x moles CO2

= 1/3 x 11.5

= 3.83 moles

Which compound has the highest precent composition by mass of strontium?

PilotLPTM [1.2K]

First find the molar masses of all of the compounds:
SrCl2 = 158.53g/mol
SrI2 = 341.43g/mol
SrO = 103.62g/mol
SrS = 119.68g/mo

Then find the molar mass of Sr in each of the compounds. Since there is only one Sr in every compound, the mass will be the same: 87.62g/mol Sr

Now divide the molar mass of Sr by each of compounds' masses:
SrCl2 = (87.62)/(158.53) = 0.553
SrI2 = (87.62)/(341.43) = 0.257
SrO = (87.62)/(103.62) = 0.846
SrS = (87.62)/(119.68) = 0.732

Now multiply each of the results by 100 to get the percent composition of Sr by mass:
(0.553)(100) = 55.3% Sr in SrCl2
(0.257)(100) = 25.7% Sr in SrI2
(0.846)(100) = 84.6% Sr in SrO
(0.732)(100) = 73.2% Sr in SrS

Thus SrO has the highest percent composition by mass of Sr

Which best describes a reaction in a state of equilibrium?

tamaranim1 [39]

The best statement which describes a reaction in a state of equilibrium is letter D. The rate of the forward reaction equals the rate of the reverse reaction and the concentrations of products and reactants are constant.

>Chemical equilibrium is defined as the state in which both reactants and products are present in concentrations which have no further tendency to change with time. This state results when the forward reaction proceeds at the same rate as the reverse reaction. The reaction rates of the forward and backward reactions are generally not zero, but equal. Thus, there are no net changes in the concentrations of the reactant(s) and product(s).
