Answer:D. It is released as heat and light.

Explanation:

Energy cannot be created nor destroyed but can be converted from one form to another. This is the law of the conservation of energy. Energy is stored in the wax. When the wax is burnt, that energy is converted to another form of energy. In this case heat and light. Energy exists in various forms in nature. Energy is always converted from one form to another.

A sample of ethanol (C2H6O) has a mass of 0.2301 g. Complete combustion of this sample causes the temperature of a bomb calorime
Keith_Richards [23]

Answer:  4.994\times 10^{-3}  moles

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to molecular mass , occupies 22.4 L at STP and contains avogadro's number 6.023\times 10^{23} of particles.

To calculate the moles, we use the equation:

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

Given mass of ethanol = 0.2301

Molar mass of ethanol = 46.07 g/mol

\text{Number of moles of ethanol}=\frac{0.2301g}{46.07g/mol}=4.994\times 10^{-3}

Thus there are 4.994\times 10^{-3}  moles of ethanol are present in the sample.
