If you have a 1234 gram sample of C4H7NO4, how many gams of Carbon would be present?

Answer: 445.4 grams of carbon would be present.

Explanation:

According to avogadro's law, 1 mole of every substance contains avogadro's number 6.023\times 10^{23} of particles and weighs equal to its molecular mass.

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}=\frac{1234g}{133g/mol}=9.28moles

As 1 mole of C_4H_7NO_4 gives = 4 moles of carbon

Thus 9.28 moles of C_4H_7NO_4 gives = \frac{4}{1}\times 9.28=37.1 moles of carbon

Mass of carbon = moles\times {\text {Molar mass}}=37.1moles\times 12g/mol=445.4g

Thus there are 445.4 grams of carbon would be present.

A 0.1375-g sample of solid magnesium is burned in a constant-volume bomb calorimeter that has a heat capacity of 3024 J/°C. The
Anna35 [415]

Answer:

-24.76 kJ/g; -601.8 kJ/mol

Explanation:

There are two heat flows in this experiment.

Heat from reaction + heat absorbed by calorimeter = 0

             q1                +                     q2                         = 0

           mΔH             +                    CΔT                        = 0

Data:

m = 0.1375 g

C = 3024 J/°C

ΔT = 1.126 °C

Calculations:

0.1375ΔH + 3024 × 1.126 = 0

           0.1375ΔH + 3405 = 0

                        0.1375ΔH = -3405

                                   ΔH = -24 760 J/g = -24.76 kJ/g

ΔH = -24.76 kJ/g ×24.30 g/mol = -601.8 kJ/mol

Which statement correctly describes the actual yield and the theoretical yield of a reaction? (1 point)
Furkat [3]

Answer:

C: The actual yield depends on the reaction conditions, but the theoretical yield varies only with reactant amounts

Explanation:

Looking at the options, the correct one is Option C because the actual yield usually depends on the conditions of the reaction, while the theoretical yield usually varies with only the amount of reactant.
