Answer:

The answer is D

Explanation:

Although natural processes continually form fossil fuels, such fuels are generally classified as non-renewable resources because they take millions of years to form and the known viable reserves are being depleted much faster than new ones are being made. ... The use of fossil fuels raises serious environmental concerns.

Answer: D. Fossil Fuel.

Explanation: Once used, can't be renewed. For example, gasoline. Once put into a gas tank of a car, and you drive that car to empty, better hope there's a gas station near by!

An archaeologist finds a 1.62kg goblet that she believes to be made of pure gold. She determines that the volume of the goblet i

Klio2033 [76]

Density equals Mass/Volume. The equation for this problem would be 1.62 kg/205 mL. If it’s easier, this can be converted to 1620 g/205 mL. The answer would be 7.902 (rounded to the nearest thousandth). Good luck!

Consider a sample of 10.0 g of the gaseous hydrocarbon C2H6 to answer the following question: How many moles are present in this

Masja [62]

<u>Answer:</u> The moles of given hydrocarbon is 0.3 moles

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

We are given:

Given mass of ethane = 10.0 g

Molar mass of ethane = $[(2\times 12)+(6\times 1)]=30g/mol$

We need to divide the given value by the molar mass.

Putting values in above equation, we get:

$\text{Moles of ethane}=\frac{10.0g}{30g/mol}=0.3mol$

In case of multiplication and division, the number of significant digits is taken from the value which has least precise significant digits. Here, the least precise number of significant digits are 1.

Hence, the moles of given hydrocarbon is 0.3 moles
