The given thermochemical equation is:

2 CO (g) + O_{2}(g) --->2CO_{2}(g) ΔH^{0} = -482 kJ/mol

Mass of CO given = 24.0 g

Moles of CO = 24.0 g CO * \frac{1 mol CO}{28 g CO} = 0.857 mol CO

Finding out the heat released to the surroundings when 24.0 g CO:

0.857 mol CO * \frac{482 kJ}{2 mol CO} =  207 kJ

Therefore, 207 kJ of heat is released to the surroundings when 24.0 g CO reacts completely.

Answer:

D

Explanation:

I think it is D. Think about it- if a human jumps, they are less than the gravitational force. But, if you are greater than the gravitational force, I think you will go into space.

Type the correct answer in the box. Express your answer to three significant figures. Iron(II) chloride and sodium carbonate rea
Ad libitum [116K]

Answer:

The reaction can produce 287 grams of iron(II) carbonate

Explanation:

To solve this question we must find the moles of iron(II) chloride that react. Using the chemical equation we can find the moles of iron(II) carbonate and its mass -Molar mass FeCO3: 115.854g/mol-

<em>Moles FeCl2:</em>

1.24L * (2.00mol / L) = 2.48 moles FeCl2

As 1 mol FeCl2 produce 1 mol FeCO3, the moles of FeCO3 = 2.48 moles

<em>Mass FeCO3:</em>

2.48mol * (115.854g / mol) =

Calculate the molecular weight of freon-12, if 122.70 liters of its vapor at 200.00
ICE Princess25 [194]

PV = nRT

Where:


P = pressure in atm = 700/760 = 0.9211atm


V = volume = 8.29L


R = gas constant, 0.08206 atm-L/mol-K


T = temperature in Kelvin = 200 + 273 = 473


n = numbers of moles  = Mass/molar mass


mass of the compound = 30.5


we can rewrite the equation above as


PV = (Mass)/(Molar mass) * RT
