Given by the name of these compounds, they are formed if one or more hydrogen atoms are substituted for halogens
X = Cl, Br, I, F
Answer: I believe it’s element symbols
Explanation: I hope we both get it right
The experimental method for measuring the change in concentration with time for the given reaction is by measuring the amount of gas a reaction releases over time.
2NO(g) + Cl₂(g) → 2NOCl(g)
<h3>What is reaction rate?</h3>
- The reaction rate is the rate at which a chemical reaction proceeds.
- Which is proportional to both the increase in a product's concentration per unit time and the decrease in a reactant's concentration per unit time.
- There is a wide range in reaction times.
- The general definition is that the term "rate of a reaction" refers to the pace at which a reaction occurs.
- As an illustration, iron rusting has a low reaction rate since the process is slow but wood burning has a high reaction rate because the process is quick.

Vapor pressure of a liquid increases with increasing temperature because increasing the temperature results in increasing kinetic energy and increase in molecular transition and motion.
What is Vapor Pressure?
- The pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) at a specific temperature in a closed system is referred to as vapor pressure.
- A liquid's evaporation rate can be determined by looking at the equilibrium vapor pressure. It has to do with how often particles tend to float away from liquids (or a solid).
- Volatile is a term used to describe a chemical that has a high vapor pressure at room temperature. Vapor pressure is the force that vapor exerts when it is present above a liquid surface.
- A liquid's molecules have an increasing kinetic energy as its temperature rises. The more molecules that convert into a vapor as a result of an increase in molecular kinetic energy, the higher the vapor pressure will be.

Answer:
These two are equivalent and valid:
Explanation:
The molecular superscripts for each atom in the <em>molecular formula</em> are determined by the number of times that the mass of the<em> empirical formula</em> is contained in the<em> molar mass</em>.
<u />
<u>1. Determine the mass of the empirical formula:</u>
:
Atomic masses:
- O: 15.999g/mol
- C: 12.011g/mol
- N: 14.007g/mol
- Cl: 35.453g/mol
Total mass:
- 15.999g/mol + 12.011g/mol + 14.007g/mol + 35.453g/mol = 77.470g/mol
<u />
<u>2. Divide the molar mass by the mass of the empirical formula:</u>
- 232.41g/mol / 77.470g/mol = 3
<u>3. Multiply each superscript of the empirical formula by the previous quotient: 3</u>
Or:
You might also write CN as a group:
