Question 1

The action of some commercial drain cleaners is based on the following reaction:

2NaOH(s) + 2Al(s) + 6H2O(l) → 2NaAl(OH)4(s) + 3H2(g)

What is the volume of H2 gas formed at STP when 6.32 g of Al reacts with excess NaOH?
◦ 8.59L
◦ 3.50 L
◦ 7.98 L
◦ 5.25L

Question 2

How many millilitres of ozone gas at 25.0 °C and 1.00 bar are needed to react with 45.00 mL of a 0.100
mol L-1 aqueous solution of KI according to the chemical equation shown below?

O3(g) + 2I-(aq) + H2O(l) → O2(g) + I2(s) + 2OH-(aq)

◦ 165 mL
◦ 54.8 mL
◦ 220 mL
◦ 110 mL

Human kidneys will clean about 1 million gallons of blood in an average lifetime.

Did you know?

As many as 28% of hospitalized patients requiring mechanical ventilators to help them breathe (for more than 48 hours) will develop ventilator-associated pneumonia. Current therapy involves intravenous antibiotics, but new antibiotics that can be inhaled (and more directly treat the infection) are being developed.

Did you know?

About 600,000 particles of skin are shed every hour by each human. If you live to age 70 years, you have shed 105 pounds of dead skin.

Did you know?

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.

Did you know?

The average adult has about 21 square feet of skin.
