b. Describe how the temperature changes within a phase and during a phase change as heat is added to a water sample. (2 points)

Rudik [331]

Hello!

Take for example the heating of water.

When heating liquid water from room temperature (25 °C) to the boiling point (100 °C), adding heat results in a direct increase in the temperature. This kind of heat is called sensible heat, because we can sense the effect of the added energy.

But when you reach 100 °C, there is a phase change from liquid to vapour, and the added heat is used to produce the phase change, and no increase in temperature is observed, only the phase change. This kind of heat is called latent heat.

Have a nice day!

¿Por qué los gases nobles tienen tendencia a no formar compuesto si como todo elemento de la tabla periódica estos tienen electr

White raven [17]

Noble gases are the least reactive of all elements. That's because they have eight valence electrons, which fill their outer energy level. This is the most stable arrangement of electrons, so noble gases rarely react with other elements and form compounds.

Which term is used to describe the reactant that is used up completely and controls the amount of product that can be produced d

givi [52]

Answer: Option (c) is the correct answer.

Explanation:

A limiting reagent is defined as a reagent that completely gets consumed in a chemical reaction. A limiting reagent limits the formation of products.

For example, we have given 5 mol of A and the reaction is $2A + 4B \rightarrow 2AB$

Whereas when 4 mol B will react with 2 mol of A. Hence, 8 mol of B will react with 4 mol A as follows.

$\frac{2}{4} \times 8$ = 4 mol

As, the given moles of A is more than the required moles. Thus, it is considered as an excess reagent.

Hence, B is a limiting reagent because it limits the formation of products.

Thus, we can conclude that limiting reactant is the term used to describe the reactant that is used up completely and controls the amount of product that can be produced during a chemical reaction.
