3Al + 3 NH4ClO4 ---> Al2O3 + AlCl3 + 3 NO + 6H20
Tresset [83]

Answer:

9.63 L of NO

Explanation:

We'll begin by calculating the number of mole in 50.0 g of NH₄ClO₄. This can be obtained as follow:

Mass of NH₄ClO₄ = 50 g

Molar mass of NH₄ClO₄ = 14 + (4×1) + 35.5 + (16×4)

= 14 + 4 + 35.5 + 64

= 117.5 g/mol

Mole of NH₄ClO₄ =?

Mole = mass /molar mass

Mole of NH₄ClO₄ = 50/117.5

Mole of NH₄ClO₄ = 0.43 mole

Next, we shall determine the number of mole of NO produced by the reaction of 50 g (i.e 0.43 mole) of NH₄ClO₄. This can be obtained as follow:

3Al + 3NH₄ClO₄ –> Al₂O₃ + AlCl₃ + 3NO + 6H₂O

From the balanced equation above,

3 moles of NH₄ClO₄ reacted to produce 3 moles of NO.

Therefore, 0.43 mole of NH₄ClO₄ will also react to produce 0.43 mole of NO.

Finally, we shall determine the volume occupied by 0.43 mole of NO. This can be obtained as follow:

1 mole of NO = 22.4 L

Therefore,

0.43 mole of NO = 0.43 × 22.4

0.43 mole of NO = 9.63 L

Thus, 9.63 L of NO were obtained from the reaction.

A major chemical spill occurred five years ago at Bakerâs Beach, the worldâs sole nesting ground for Merrick sea turtles, and pr
AfilCa [17]

Answer:

<em>B. Female Merrick sea turtles begin returning to Bakerâs Beach to lay their eggs when they are ten years old.</em>

Explanation:

Firstly, There was an oil spill five years ago-no eggs hatched.

Now, the number of females coming back to the lay eggs has increased somewhat since the last five years.

The theory is that a period of 5 years is sufficient to assess effect on population.

If the breeding cycle has been found to be ten years long, then the impact of the oil spill on the population (as observed by the number of females returning to lay eggs) will only be perceived in the 10th year.

It undermines the argument that the oil spills don't impact the public.
