If the fuel does not have enough oxygen to burn completely CO2 and H2O, there can be two additional products. What are they?

1 answer:

5 0

Assuming you're referring to a combustion reaction, the products can also be N2, CO, and NOx, x being the subscript or number of oxygens in the nitrogen-oxygen compound.

I can't answer this question without knowing what the specific heat capacity of the calorimeter is. Luckily, I found a similar problem from another website which is shown in the attached picture.

Q = nCpΔT
Q = (1.14 g)(1 mol/114 g)(6.97 kJ/kmol·°C)(10°C)(1000 mol/1 kmol)
Q = +6970 kJ

A flask contains 5.0g of neon gas at a temperature of 35°C. The pressure gauge indicates 0.37atm inside the flask. What is the v

DaniilM [7]

Answer:

The volume of the neon gas is 17.07 L.

Explanation:

The ideal gas equation describes the relationship among the four variables P, V, T, and n. An ideal gas is a hypothetical gas whose pressure-volume-temperature behavior can be completely accounted for by the ideal gas equation.

In order to calculate the volume, first we need to convert the grams of neon to moles:

28.18 g Ne ------ 1 mol Ne

5.0 g Ne---------- x= 0.25 mol Ne

Now, using the ideal gas equation we calculate the volume:

$pV= nRT$

$V= nRT ÷ p$

$V= (0.25 mol × 0.082 L.atm/mol.K × 308.15 K ÷ 0.37 atm$

V= 17.07 L

Pam observed many small earthworms in the backyard of her house after a heavy rain. What most likely formed the earthworms?

AlekseyPX

Answer: Option (b) is the correct answer.

Explanation:

When it rains, then mud in the backyards become wet. It is known that earthworms live inside earth and diffusion of oxygen gets slower through water than through air.

As a result, supply of oxygen to the worms decreases in wet mud hence, they come to the surface in order to breathe.

Thus, we can conclude that wet mud in the backyard most likely formed the earthworms.
