What else can I help you with?
Is it advisable to heat ethanol directly with a Bunsen flame?
It is not advisable to heat ethanol with a Bunsen flame because of the low boiling point and its volatile nature. Ethanol is also flammable, and therefore it is best to heat ethanol on a heat plate or steam condenser.
What happens to acetone molecules when you add heat to a beaker of liquid acetone?
When heat is added to a beaker of liquid acetone, the acetone molecules gain kinetic energy and move more rapidly. This increased energy causes the acetone molecules to evaporate and transition to the gas phase. If the temperature is high enough, the acetone molecules may also undergo further reactions, such as decomposition or combustion.
Why water bath must be used while heating ethanol and acetone?
A water bath is used to regulate the temperature during heating to prevent the solvent from reaching its boiling point and potentially igniting. This method provides a safer way to heat volatile solvents like ethanol and acetone without the risk of fire or explosion.
What dissolves iodine?
Iodine can be dissolved in various solvents, such as ethanol, water, or organic solvents like acetone or chloroform. Heat can also help speed up the dissolution process.
What happens to acetone molecules when you add heat to a breaker of liquid acetone?
When heat is added to a beaker of liquid acetone, the acetone molecules gain energy and begin to evaporate into the air as a gas. The increased temperature causes the molecules to move faster and escape the liquid phase.

What is the heat of reaction for ethanol fermentation from glucose?
The heat of reaction for ethanol fermentation from glucose is exothermic, meaning it releases heat. This is because the process of fermentation involves breaking down glucose to produce ethanol and carbon dioxide, which releases energy in the form of heat.
What happens when you heat up acetone?
When you heat up acetone, it will vaporize and turn into a gas. Acetone has a low boiling point of 56°C (132.8°F), so it evaporates quickly. It is important to handle acetone carefully when heating it up, as it is flammable.
What is the heat capacity of ethanol and how does it affect its use in various applications?
The heat capacity of ethanol is 2.44 J/gC. This means that ethanol can absorb and release heat efficiently. This property makes ethanol useful in applications such as fuel, solvent, and in the production of alcoholic beverages.
Latent heat of ethanol?
Specific heat of ethanol: 2.46 g/mol*degree CSpecific heat is the heat required to raise the temperature of a given mass by 1 degree Celsius.The formula is Q = cmΔTQ = Heat addedc = Specific heatm = MassΔT = Change in temperature
Does water affect the heat of combustion of ethanol?
There are two angles to this question: 1. If your ethanol is contaminated with water it will reduced the amount of useful heat generated since the water will boil off while the ethanol is burning. 2. The water generated as a result of combustion is included as a term in the calculation of heat of combustion.
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 does your plam feel cool when you put some acetone on it?
Because the acetone takes some of the heat from your hand and uses it to evaporate.
