Answer:

6.02 x 10²³ seconds ≈ 1.909 x 10¹⁵ decades

Explanation:

Second is the SI unit of time, which is denoted by the symbol s. In one minute there are 60 seconds.

So, in one hour there are 60 mins = 60 × 60 seconds = 3600 seconds.

In one day there are 24 hours = 24 × 60 minutes = 24 × 60 × 60 seconds = 86,400 seconds.

In one year there are approximately 365 days = 365 × 24 hours = 365 × 24 × 60 minutes = 365 × 24 × 60 × 60 seconds = 31536000 seconds.

Since, a decade is defined as the period<u> of ten years.</u>

So, a decade = 10 years = 10 × 365 days = 10 × 365 × 24 hours = 10 × 365 × 24 × 60 minutes = 10 × 365 × 24 × 60 × 60 seconds = 315360000 seconds.

Since, 315360000 seconds = 1 decade

Therefore, 6.02 x 10²³ seconds = 6.02 x 10²³ seconds ÷ 315360000 seconds ≈ 1.909 x 10⁻⁸ x 10²³ = 1.909 x 10¹⁵ decades

What expression approximates the volume of O2 consumed, measure at STP, when 55 g of Al reacts completely with excess O2?2 Al(s)
nikdorinn [45]

Answer : The volume of O_2 consumed are, 0.75\times 2\times 22.4 L.

Explanation :

The balanced chemical reaction will be:

4Al(s)+3O_2(g)\rightarrow 2Al_2O_3(s)

First we have to calculate the moles of Al.

\text{Moles of }Al=\frac{\text{Mass of }Al}{\text{Molar mass of }Al}

Molar mass of Al = 27 g/mole

\text{Moles of }Al=\frac{55g}{27g/mol}=2mole

Now we have to calculate the moles of O_2.

From the reaction we conclude that,

As, 4 mole of Al react with 3 moles of O_2

So, 2 mole of Al react with \frac{3}{4}\times 2=0.75\times 2 moles of O_2

Now we have to calculate the volume of O_2 consumed.

As we know that, 1 mole of substance occupies 22.4 liter volume of gas.

As, 1 mole of O_2 occupies 22.4 liter volume of O_2 gas

So, 0.75\times 2 mole of O_2 occupies 0.75\times 2\times 22.4 liter volume of O_2 gas

Therefore, the volume of O_2 consumed are, 0.75\times 2\times 22.4 L.
