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

Kindly Mark Brainliest, Thanks!!!

A balloon inflated in a room that is 34 C has a volume of 5.00 liters. The room is then heated to a temperature of 68 C. What is
Eduardwww [97]

Answer:-

5.554 litres

Explanation:-

Initial Volume V 1 = 5.00 litres

Initial temperature T 1 = 34 C + 273 = 307 K

Final temperature T 2 = 68 C + 273 = 341 K

Using the relation of Charles Law (V 1 / T 1) = (V 2 / T 2)

New Volume V 2 = V1 x T2 / T1

Plugging in the values

V2 = 5.00 litres x 341 K / 307 K

= 5.554 litres.
