How much energy is absorbed when 356 g of ethanol 46.0 g molboils The heat of vaporization of ethanol is 38.6 kJ mol?
To calculate the energy absorbed, first convert the mass of ethanol from grams to moles. 356 g of ethanol is 356/46.0 = 7.74 moles. Then, multiply the moles of ethanol by the heat of vaporization: 7.74 mol * 38.6 kJ/mol = 298.56 kJ of energy absorbed.
How can ethanol reduce carbon emissions?
Ethanol is a fuel made from plants. When we burn this fuel, it does emit carbon dioxide, but of course this was originally absorbed from the atmosphere by the plants, so there is no net increase in the amount of atmospheric carbon dioxide no matter how much ethanol we use (apart from a small amount produced by generating electricity used in the production of the ethanol). A disadvantage of using ethanol for motor fuel is that its production competes with food crops.
Does ethanol contain water?
Yes, ethanol can contain water as it is a common impurity in ethanol. Ethanol is a type of alcohol that can be mixed with water.
How do you separate ethanol from aqueous ethanol?
Ethanol can be separated from aqueous ethanol through a process called distillation. In distillation, the mixture is heated to evaporate the ethanol, which is then condensed back into liquid form. The condensed ethanol can then be collected as a separate product.
What is te symble of ethanol?
The formula for ethanol is C2H5OH

When you drink ethanol it is absorbed in what three places of the body?

How much energy is absorbed when 356 g of ethanol 46.0 gmol boils?
The heat of vaporization of ethanol is 38.6 kJ/mol-298 - 299 KJ
Can you put rum on a newborns head to relax him?
Doing so might calm a baby because ethanol can be absorbed transdermally.
What is the Heat of formation of Liquid Ethanol?
The heat of formation of liquid ethanol is approximately -277.7 kJ/mol. This value represents the heat released or absorbed when one mole of liquid ethanol is formed from its elements in their standard states.
Why is ethanol from sugar cane called biofuel but ethanol from ethene not?
Ethanol from sugarcane is known as a biofuel because the ethanol is derived from a biological, renewable source. Burning this releases recently absorbed carbon dioxide so it is part of the carbon cycle. Ethanol from ethene (or ethylene) is typically produced from fossil fuels, namely petroleum, so it is a non-renewable resource. Burning this releases carbon dioxide that was absorbed millions of years ago, so it is all extra. Burning fossil fuels is causing global warming.
What would happen if you drank pure ethanol and then lit yourself on fire be specific - point form acceptable?
The ethanol might have it's head absorbed by the fire causing your innards to freeze. Your biggest worry would be being frozen to death.
Why 70 ethanol is more effective than 90?
70% has more water, thus more readily absorbed by cells. tricks the cells into admitting it
What part of your body absorbs alcohol?
Roughly 20% is absorbed through the stomach wall, depending on the contents of the stomach. The rest is absorbed in the small intestine.
How can ethanol reduce carbon emissions?

A disadvantage of using ethanol for motor fuel is that its production competes with food crops.
What happens when you put frozen ethanol into liquid ethanol?
When you put frozen ethanol into liquid ethanol, the frozen ethanol will begin to melt and mix with the liquid ethanol. Both states of ethanol will reach an equilibrium temperature, and the frozen ethanol will ultimately dissolve into the liquid ethanol to form a homogeneous solution.
Is distilled ethanol similar to pure ethanol?
Yes, distilled ethanol is similar to pure ethanol. Distilled ethanol is produced using distillation to purify the ethanol, resulting in a high level of purity. Pure ethanol refers to ethanol that is free from impurities, and distilled ethanol typically meets this criteria.
