PLEASE HELP I WILL MARK YOU BRAINLIEST How many moles of FeCl2 do you need to react 5 moles of Cl2?

Chemistry
1 answer:
lisabon 2012 [21]2 years ago
4 0

Answer:

1. Ok, so you have a 1:1 ratio of FeCl2 to FeCl3, which is shown by the fact that if you react 2 moles of FeCl2 you get 2 moles of FeCl3. So therefore, if you react 4 moles of FeCl2, you'd form 4 moles of FeCl3.

2. You have a 1:2 ratio of Cl2 to FeCl2, for every 1 mole of Cl2, you need 2 moles of FeCl2, so therefore, for 7 moles of Cl2, you need 2x7moles = 14 moles

3. 1:1 ratio. So you start with 2.28moles.

4. 1:2 ratio of Cl2 to FeCl2, so therefore to get from FeCl2 to Cl2 you need to divide by 2. Therefore, you need 3.25moles / 2 = 1.625 moles

What is the amount of heat required to complete MELT a 200 gram sample of H2O(s)
wolverine [178]

Answer:

66800 J

Explanation:

From the question given above, the following data were obtained:

Mass (m) = 200 g

Heat (Q) required =?

The heat required to melt the 200 g sample of water can be obtained as:

Mass (m) = 200 g

Latent heat of water (L) = 334 J/g

Heat (Q) required =?

Q = mL

Q = 200 × 334

Q = 66800 J

Thus, 66800 J of heat energy is required to melt the sample of water.

Dry ice is solid carbon dioxide. Instead of melting, solid carbon dioxide sublimes according to the following equation: CO2(s)→C
GREYUIT [131]

Answer:

m=8.79kg

Explanation:

First of all we need to calculate the heat that the water in the cooler is able to release:

Q=\rho * V*Cp*\Delta T

Where:

  • Cp is the mass heat capacity of water
  • V is the volume
  • \rho is the density

Q=1 g/cm^3 *15000 cm^3*4.184 \frac{J}{g*^{\circ}C}*(10-90)^{\circ}C

Q=-5020800 J=-5020.8 kJ

To calculate the mass of CO2 that sublimes:

-Q=\Delta H_{sub}*m

Knowing that the enthalpy of sublimation for the CO2 is: \Delta H_{sub}=571 kJ/kg

5020.8 kJ=571 kJ/kg*m

m=\frac{5020.8 kJ}{571 kJ/kg}=8.79kg
