Answer:

s<p<q<r

Explanation:

Given

Element s displaces p from its oxide. Thus, s is more reactive that p

p reacts with cold water  but element q cannot react with cold water. Thus,

p is more reactive than q

Element q is able to react with weak or dilute acids but element r in unable to react with weak or dilute acids. Thus, q is more reactive that r

The order of four elements on the basis of their reactivity in descending order is as follows

s<p<q<r

Answer:

CH3CH=NH2+>CH3CH2NH3+

Explanation:

If we look at the both species under review, we will realize that they are both amines hence they possess the polar N-H bond.

Electrons are ordinarily attracted towards the nitrogen atom hence making both compounds acidic. It is worthy of note that certain features of a compound may make it more acidic than another of close structural proximity. 'More acidic' simply means that the proton is more easily lost.

CH3CH=NH2+ contains an sp2 hybridized carbon atom which is highly electronegative and further withdraws electron density from the N-H bond thereby leading to a greater acidity of CH3CH=NH2+ compared to CH3CH2NH3+

A solution that contains the maximum amount of solute that is soluble at a given temperature is said to be —
solniwko [45]

Answer: Saturated

A solution that contains the maximum amount of solute that is soluble at a given temperature is said to be saturated.

Explanation:

A Saturated solution is one that contains as much (i.e maximum) solute as it can dissolve at that temperature in the presence of undissolved solute particles.

For instance: if a given volume of water can only dissolve a certain amount of salt in it at room temperature, then, more salt added will not dissolve.

Thus, making the solution saturated.

Select the correct answer.
adelina 88 [10]

Answer:

OB. Energy transfer would occur between the copper bars and the surroundings.

Explanation:

We define an isolated system as a system in which there is neither exchange of material nor energy while an open system is one in which materials and energy can be exchanged with the environment.

Given an open system consisting of two copper bars at different temperatures, energy will not only be exchanged between the copper bars but also between the copper bars and the environment.

Is the method for converting molecules to moles the same as that for atoms?
arlik [135]

Answer:

One mole is the Avogadro's number of particles (atoms, molecules, ions or electrons) in a substance. Converting to moles is fairly easy because the conversion is always the same.
