The evaporation of a drop of water in an air stream is determined by the rate of transfer of heat and water vapour between the drop surface and the ambient air. If these transfer processes are governed by molecular diffusion the appropriate equations take a well known form. I hope this can help

An unbalanced equation is shown. In this reaction, 200.0 g of FeS2 is burned in 100.0 g of oxygen, and 55.00 g of Fe2O3 is produ

Percent yield is calculated as the actual yield divided by the theoretical yield multiplied by 100.

Actual yield = 55 g ( 1 mol / 159.69 g ) = 0.34 mol Fe2O3

To find for the theoretical yield, we first determine the limiting reactant.

100 g O2 ( 1 mol / 32 g) = 3.13 mol O2
200 g FeS2 (1 mol / 119.98g) = 1.67 mol FeS2

Therefore, the limiting reactant is O2.

Theoretical yield = 3.13 mol O2 ( 2 mol Fe2O3 / 11 mol O2 ) = 0.57 mol Fe2O3

Percent yield = (0.34 mol / 0.57 mol) x 100 = 59.74%

2. What is the mass of a car with a momentum of 10,000.00 kgm/s, traveling at 15.0 m/s?
Svetradugi [14.3K]

Answer:

666.67 kg is the mass of a car.

Explanation:

Momentum is defined as amount of motion possessed by the the moving body. It is mathematically calculated by multiplying mass into velocity by which object is moving.

Momentum(P)=Mass(m)\times Velocity(v)

Mass of the car = m =?

Velocity of the car = v = 15.0 m/s

Momentum of the car = P = 10,000.00 kgm/s

m=\frac{P}{v}

m=\frac{ 10,000.00 kgm/s}{15.0 m/s}=666.67 kg

666.67 kg is the mass of a car.
