2. How many moles are in 2.8 Liters of CO2 gas?
andrew-mc [135]

Answer:

0.125 moles

Explanation:

2.8 litres is equivalent to 2.8dm³

At STP,

1 mole = 22.4 dm³

x mole = 2.8 dm³

Cross multiply

22.4x = 2.8

Divide both sides by 22.4

x = 2.8/22.4

x = 0.125

Can someone easily explain to me how to do reaction rates?
iVinArrow [24]

Explanation:

Reaction rate is a measure of speed of a chemical reaction.

Usually, based on rates, reactions can be divided into two parts:

  • Slow reactions which usually takes a long time.
  • Fast reactions which takes place completely in seconds or microseconds.

Reaction rate can be defined as a change in the concentration of a reactant or product per unit time:

      The unit is  mol dm⁻³ s⁻¹

Reaction rate = \frac{change in concentration of a reactant and product}{time taken }

The measurement of the reaction rate is based on the disappearance of a reactant or appearance of a product with increasing reaction time.
