Poisonous carbon monoxide can be produced by furnaces in basements if the combustion and exhaust are not complete. Calculate the

density of carbon monoxide in g/L at 292 K and 1.00 atm of pressure to determine whether it is more or less dense than air. If it is more dense, it will remain in the basement; if it is less dense it will rise to the upper levels of the house. The density of dry air is 1.20 g/L.

Answer:

The Density of carbon monoxide is 1.17g/L. It is less dense than dry air which has a density of 1.20 g/L.

Therefore, the carbon monoxide will rise to the upper level of the house.

Explanation:

Step 1:

Data obtained from the question. This includes the following:

Temperature (T) = 292 K

Pressure (P) = 1 atm

Density of carbon monoxide =?

Density of air =?

Step 2:

Obtaining an expression for the density. This is illustrated below:

From the ideal gas equation:

PV = nRT (1)

Recall:

Number of mole (n) = mass (m)/molar mass (M)

n = m/M

Substitute the value of n into equation 1.

PV = nRT

PV = mRT/M

Divide both side by P

V = mRT/MP

Divide both side by m

V/m = RT/MP

Invert the equation

m/V = MP/RT (2)

Recall:

Density (ρ) = mass (m) / volume(V)

ρ = m/V

Replacing m/V with ρ in equation 2

m/V = MP/RT

ρ = MP/RT

Where R is the gas constant (0.082atm.L/Kmol)

M is Molar Mass of CO ( 12 + 16 = 28g/mol)

Step 3:

Determination of the density of carbon monoxide. The density of carbon monoxide can be obtained as follow:

T= 292 K

P = 1 atm

R = 0.082atm.L/Kmol

M = 28g/mol

Density (ρ) =?

ρ = MP/RT

ρ = (28 x 1) / (0.082 x 292)

ρ = 1.17g/L

The Density of carbon monoxide is 1.17g/L. It is less dense than dry air which has a density of 1.20 g/L.

Therefore, the carbon monoxide will rise to the upper level of the house

Calculate the energy required to heat 322.0g of ethanol from −2.2°C to 19.6°C . Assume the specific heat capacity of ethanol und
just olya [345]

Answer:

There is 17.1 kJ energy required

Explanation:

Step 1: Data given

Mass of ethanol = 322.0 grams

Initial temperature = -2.2 °C = 273.15 -2.2 = 270.95K

Final temperature = 19.6 °C = 273.15 + 19.6 = 292.75 K

Specific heat capacity = 2.44 J/g*K

Step 2: Calculate energy

Q = m*c*ΔT

⇒ m = the mass of ethanol= 322 grams

⇒ c = the specific heat capacity of ethanol = 2.44 J/g*K

⇒ ΔT = T2 - T1 = 292.75 - 270.95 = 21.8 K

Q = 322 * 2.44 * 21.8 = 17127.8 J = 17.1 kJ

There is 17.1 kJ energy required

What do helium (He), neon (Ne), and argon (Ar) have in common?
IrinaK [193]

Answer:

The answer is: D

Explanation:

A. They have the same number of electron energy shells.  Is false, all the elements are in different periods so, they have different number of lectron energy shells.

B. They are all Halogens.  No, is wrong, halogens are F, Cl ,Br

C. They have the same number of electrons.  is wrong, if they had the same number of electrons they must be they same element and they aren't the same.

D. They are all Noble gases. Yes, it's true they are noble gases, they are the first group in the periodic table from the right.

Which stament about energy is mostly correct
klasskru [66]
I would say C is the most correct. 
In D it depends on what water source you're using. Let's say it is a waterfall, then the source of the water (melting ice or a lake) may disappear in the future. 
If you're using underwater "windmills" placed in the ocean, then you would expect it to last a while as the ocean will not disappear in the near future.
