Answer:

34.8 moles of CO₂ are produced

Explanation:

This is the reaction:

1C₅H₁₂ + 8O₂  →  6H₂O  +  5CO₂

Ratio is 1:5. We make a rule of three

1 mol of pentane can produce 5 moles of CO₂

Then, 6.96 moles of pentane may produce (6.96 .5) / 1 = 34.8 moles

You discover a piece of jewelry that you think might be made of silver. You place the item on a balance and determine that it ha
Amanda [17]

No, this item is not made of pure silver because if it has been made from pure silver that it would have displaced only 1.16cm³ of water but due to the addition of some other low-density element it displaces 1.9cm³ of water.

<u>For pure silver</u>

density of pure silver is = 10.49 g/cm³

mass of silver = 12.2 gram

since, density = mass/volume

          volume = mass/density

                        = 12.2/10.49 cm³

                         = 1.16 cm³

But the actual displaced water is <u>1.9cm³</u>, which means some other element of lower density has been added.

Therefore, it is clear that the given jewelry is not made of pure silver.

The earth formed 4600 million years ago. What percentage of the Earth’s age has the atmosphere been its current composition
nata0808 [166]

Answer: 4.35%

Explanation:

Scientists estimate that the current composition of gases in the Earth's atmosphere has been stable for the last 200 million years or so.

If the Earth was formed 4,600 million years ago then the percentage of her age that the atmosphere has been in its composition is:

= 200 / 4,600 * 100%

= 4.35%
