Consider the complex ion [CO(NH3)6]3+. Which response contains all of the following statements that are true, and no false state

Result:

94.7 %

Explanation:

The balanced reaction is:

2 S + 3 O₂ → 2 SO₃

The stoichiometric mole ratio is:

S: 2 moles

O₂: 3 moles

Moles are calculated as mass divided by molar mass:

n = w / m

where n = moles, w = mass, m = molar mass.

Given:

For sulfur: w = 6.0 g, molar mass = 32 g/mol, so n = 6 / 32 = 0.1871 mol

For oxygen: w = 5.0 g, molar mass = 32 g/mol, thus n = 5 / 32 = 0.15625 mol

Comparing to stoichiometric ratios, sulfur is in excess, so oxygen is the limiting reagent, controlling product formation.

Using proportions:

3 mol O₂ produce 2 mol SO₃, so 1 mol O₂ yields 2/3 mol SO₃.

Therefore, 0.15625 mol O₂ yields (2/3) × 0.15625 = 0.1042 mol SO₃.

Mass of SO₃ produced = n × molar mass = 0.1042 mol × 80 g/mol = 8.340 g

The percentage yield is actual yield divided by theoretical yield times 100:

Percent yield = (7.9 g / 8.340 g) × 100 = 94.7 %

<span>To determine the specific heat of a solid sample, I’d begin by measuring the mass of the solid. Then, I would prepare a sufficient quantity of water at room temperature to fully submerge the solid. This water would go in an insulated container. I'd then heat the solid to a known temperature. Next, I’d record both the temperature of the solid and the water. After that, I'd submerge the heated sample in the water, allowing them to reach thermal equilibrium. I would then note this final equilibrium temperature. The temperature difference between the heated sample and the equilibrium state indicates the change in temperature of the solid. Given the known mass, initial temperature of the water, and the equilibrium temperature, I can calculate the energy transferred from the solid to the water. With the mass of the sample, the change in temperature of the solid, and the transferred energy, I have enough information to find the specific heat of the solid sample</span>

The alteration in temperature recorded is 84.7°C. To determine this temperature change, we utilize the equation: q = mcΔT, where q is the heat absorbed, m the mass of the substance, and c the specific heat capacity. Here, the heat absorbed equals 1 kCal (or 1000 Cal), the steel mass amounts to 100 g, and the specific heat of steel is represented at 0.118 Cal/g.°C. Plugging in these values reveals the temperature change to be 84.7°C.

Prior to beginning the calculations, let’s convert the units into those we require:
1- For the distance:1 mile = 1609 meters
                                          = 1609 x 100 = 160900 cm
                                          = 1609 / 1000 = 1.609 km
                                          = (160900 x 1 ) / 2.54 = 63346.45 in
 2- For the time:13 minutes = 13 / 60 = 0.2166 hours
                                            = 13 x 60 = 780 seconds

Now, we can proceed with the calculations:
velocity is determined using this formula:
velocity = distance / time

(a) in/seconds
velocity =  63346.45 in / 780 sec = 81.213 in / sec

(b) m/min
velocity = 1609 m / 13 min = 123.769 m/min

(c) km/hr
velocity = 1.609 km / 0.2166 hr = 7.428 km/hr
