Answer:

The reaction vessel will feel cool

Explanation:

In an endothermic reaction, heat is absorbed by the reaction system from the surrounding. The withdrawal of heat from the surrounding causes the reaction vessel to feel cool.

Hence when an endothermic reaction is going on, the reaction vessel feels cool when touched.

Answer:

The flask would probably feel cooler than before the reaction started.

Explanation:

An endothermic reaction means that it needs heat to continue. The required heat will be taken from the flask and by touching it the reaction reactants will cause the solution contained in the flask to cool with a drop in temperature.

Which of these charges has the greatest magnitude

Natalka [10]

Answer:

magnitude means absolute value, so the one that is greastest, like |-7| and |4| even id |-7| is a negative number, but it is still the one farthest away from 0, so |-7| is greater than |4|.

That is the way to find the greatest magnitude, but because I don't know your numbers so I can not answer your question, but this is the way to solve for it.

The pressure of the gas is expected to increase in accordance to Boyle's law.

<h3>What is Boyle's law?</h3>

Boyle's law states that, the volume of a given mass of gas is inversely proportional to its pressure at constant temperature.

By implication, when the piston is lowered and the volume of the gas is decreased, the pressure of the gas is expected to increase in accordance to Boyle's law.

Explain why 1 mole of diethyl ether requires less heat to

gizmo_the_mogwai [7]

The quantity of heat required to vapourize 1 mole of a substance depends on the kind of intermolecular forces between the molecules of the substance. Diethyl ether molecules are held together by weak dispersion forces compared to the stronger hydrogen bonding in ethanol. Therefore, 1 mole of diethyl ether requires less heat to vapourize than is required to vapourize 1 mole of ethanol.

Intermolecular forces hold the molecules a substance together in a given state of matter. The properties of a substance such as boiling point, melting point etc are dependent on the nature of intermolecular forces holding the molecules of the substance.

Diethyl ether molecules are held together by weak dispersion forces while molecules of ethanol are held together by hydrogen bonds.

Since hydrogen bonds are much stronger than dispersion forces, a greater quantity of heat is required to break the intermolecular hydrogen bonds in ethanol in order to vapourize them than is required to vapourize diethyl ether.

Therefore, owing to stronger intermolecular forces between molecules of ethanol, less heat is required to vapourize than is required to vapourize 1 mole of ethanol.
