4 0

At the triple point on a phase diagram, the state(s) of matter exist is option C: Solid, Liquid and Gas.

<h3>What states of matter exist at the triple point?</h3>

In a state of pressure and temperature of a given triple point, all three phases (known to be the solid, liquid and gas state) are seen to often exist in equilibrium.

Note that the triple point is said to be one that stands for  the lowest pressure in which a liquid phase can live in equilibrium with that of the solid or vapor.

Hence, the statement of At the triple point on a phase diagram, the state(s) of matter exist is option C: Solid, Liquid and Gas is true.

When 1 mole of H2(g) reacts with F2(g) to form HF(g) according to the following equation, 542 kJ of energy are evolved H2(g) + F
topjm [15]

Answer: The reaction is exothermic. The value of q is  -542 kJ.

Explanation:

Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and  for the reaction comes out to be positive.

Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and  for the reaction comes out to be negative.

Thus H_2(g)+F_2(g)\rightarrow 2HF(g) evolves heat , it is exothermic in nature. The value of q is -542kJ.

13. What is the volume of 17.88 mol of Ar at STP?
weeeeeb [17]

Answer:

Explanation:

1 mol of ideal gas at STP occupies 22.4 (or 22.7 depending on the convention being used for STP) liters in volume. I will use 22.4 so 17.88*22.4 = 400.5 L

What is the relationship between metals and the number of electrons in the outer level?
gayaneshka [121]
Elements in group 1-2, 13-18, the number of valence electrons is related to the group number. For example, in the first group, the alkali metals there is one valence electron, however in group 13, there are 3 valence electrons. Valence electrons are also known as the outershell electrons.
