The question is incomplete, here is the complete question:

Which formula equation shows a reversible reaction?

A: 2Na+F_2\rightarrow 2NaF

B: CaCO_3\rightarrow CaO+CO_2

C: NH_4Cl(s)\rightleftharpoons 2NH_3(g)+HCl(g)

D: 2H_2O_2(aq.)+Pt\rightarrow 2H_2O(l)+O_2(g)

<u>Answer:</u> The reversible reaction is NH_4Cl(s)\rightleftharpoons 2NH_3(g)+HCl(g)

<u>Explanation:</u>

Reversible reaction is defined as the reaction in which the products formed react together to give the reactants back. For general reversible chemical equation:

A+B\rightleftharpoons C+D

Irreversible reaction is defined as the reaction in which the reactants only lead to products and the reaction do not proceed back. For general irreversible chemical reaction:

A+B\rightarrow C+D

For the given options:

The reaction having an equilibrium sign between the reactants and products is equation C.

Hence, the reversible reaction is NH_4Cl(s)\rightleftharpoons 2NH_3(g)+HCl(g)

How can professionals increase their levels of stress as a result of personal work habits?
zmey [24]

Answer:

A

Explanation:

Developing work ethics won't lower your stress although it may make your conscience a little happier. Not B

Not C. Procrastinating just makes things harder. The mountain of things to do is not diminishing at all and your stress knows it.

Not D. Although D is the second best answer, setting goals is not really an action. It is a plan for how to work. But it is not work. Still having a goal is useful.

The answer is A. Just keep hitting what you have to do at a steady pace.

Fynjy0 [20]
The answer to this question would be: 2 mol

To answer this question, you need to know the molecular weight of Potassium. Molecular weight determines how much the weight of 1 mol of a molecule has. 
Potassium or Kalium molecular weight is 39.1 gram/mol. Then, 78.20gram of potassium should be: 78.20g/ (39.1g/mol)= 2 mol

What is the relationship between gas particles and pressure​
anygoal [31]

Answer:

For a fixed mass of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. Or Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship. If volume increases, then pressure decreases and vice versa, when the temperature is held constant..

Explanation:

Hope it helps you..

Y-your welcome in advance..

Match the following chemical reactions:
S_A_V [24]

Answer:

Synthesis - 4

reversible- 2

exchange- 1

decomposition-3

Explanation:

In synthesis reaction two or more components combines to form a single product. example 2H2+O2⇒2H2O

In reversible reaction two reactants combine to form two products . The products then reacts and forms back the reactants. example N2 +3H2 ⇒2NH3

In exchange reaction there is an alternation of ions of reactants to form new products. AB+CD ⇒AC + BD

In decomposition reaction, molecules of a compound break down by the action of heat or light or catalyst. example CaCO3 ⇒CaO +CO2
