Answer:

The concentration of hydrogen ions is 0.07 M

Explanation:

HCl is a strong acid. When it dissolves in water, it dissociates completely in H⁺ and Cl⁻ ions.

From the definition of pH:

pH = - log [H⁺]  

We introduce the pH of the solution (1.14) and calculate the concentration of hydrogen ions ([H⁺]) in M :

[H⁺] = 10^{-pH}= 10^{-1.14}= 0.0724 M= 0.07 M

What happens to the concentration of the reactants and products during the course of a forward chemical reaction
chubhunter [2.5K]
Hello!

The concentration of the reactants decreases and the concentration of products increases during the course of a forward chemical reaction.

A chemical reaction is a thermodynamical process in which two or more substances (called reagents) undergo transformation by the breaking and rearrangement of their chemical bonds to form another substance(s), called products. In a forward chemical reaction, the reagents are being consumed, so their concentration will decrease, increasing the concentration of products as they are the result of the reaction. 

The study of how concentration changes with time in a chemical reaction is called reaction kinetics. 

Have a nice day!

What is the similarity between teeth and eggshells?
topjm [15]

Explanation:

Because they share a similar composition, similar chemicals affect their structures in positive or negative ways. For example, fluoride – a staple in many dental practices – strengthens both enamel and eggshells and helps protect them from acids. Acids weaken and break down both substances. Scientists find this particularly concerning given that the ocean is growing increasingly acidic. They fear this may weaken the eggs of some marine species and harm their chance of survival. Most dentists recommend limiting aggressively acidic foods and beverages such as soft drinks.
