Answer:

The history of basketball began with its invention in 1891 in Springfield, Massachusetts by Canadian physical education instructor James Naismith as a less injury-prone sport than football. Naismith was a 31-year old graduate student when he created the indoor sport to keep athletes indoors during the winters.

Question 1-8

JulijaS [17]

If 28.0 grams of a gas occupies 22.4 liters at STP, the gas could be carbon monoxide, CO

<h3>Ideal gas </h3>

We understood from the ideal gas equation that 1 mole of any gas occupies 22.4 liters at standard temperature and pressure (STP)

<h3>How to determine the identity of the gas</h3>

To determine the identity of the gas, we shall determine the mass of 1 mole of each gas. This can be obtained as

For C₂H₂

1 mole of C₂H₂ = (12×2) + (2×1) = 26 g

For C₂H₆

1 mole of C₂H₆ = (12×2) + (6×1) = 30 g

For CO₂

1 mole of CO₂ = 12 + (16×2) = 44 g

For CO

I mole of CO = 12 + 16 = 28 g

From the above illustrations, we can see that 1 mole of CO is equivalent to 28 g.

Thus, the correct answer to the question is CO
