Answer:

1.034 L

Explanation:

P1 V1 = P2 V2

P1 V1 / P2 = V2

2.4 (2.5) / 5.8 = V2 = 1.034 L

If 2.03 g of oxygen react with carbon monoxide, how many grams of CO2 are formed?
mamaluj [8]

Answer:

The suitable equation for this reaction is

2CO + O₂ -----> 2CO₂

Here, we are given that we have 2 grams of O₂

From the equation, we can see that 2 * Moles of O₂ = Moles of CO₂

Moles of O₂:

2/32 = 1/16 moles

Therefore, the number of moles of CO₂ is twice the moles of O₂

Moles of CO₂ = 2 * 1/16

Moles of CO₂  formed = 1/8 moles

Mass of CO₂  formed = Molar mass of CO₂ * Moles of CO₂

Mass of CO₂  formed = 44 * 1/8

Mass of CO₂  formed = 5.5 grams

Hence, option B is correct

What is the average kinetic energy of 1 mole of a gas that is at 100 degrees Celsius?
Paha777 [63]
The average kinetic energy of an ideal gas is calculated as 

KE_avg = 3/2 kT

where T is the temperature in Kelvin and k=R/N_A; R is the universal gas constant and N_A is the number of moles.

Thus, upon substitution we get

KE_avg = 3/2(8.314/1)(100+273)
KE_avg = 3/2(8.314)(373)
KE_avg = 4651.683

The average kinetic energy of 1 mole of a gas at 100 degree Celsius is 4651.683 J.

The paper clips will magnetically connect to the nail. With the copper wire wrapped around then nail, it makes a magnetic field that, when powered will cause metal objects to come toward it, hence why it is called an "electromagnet".

Hope this helps!!!
