A substance joined by this type of bond shares electrons
1 answer:
Answer: Covalent
Explanation:
A covalent compound is formed when an element shares its valence electron with another element. This compound is formed between two non metals. Example:
An ionic compound is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element or the metal and the element which accepts the electrons is known as electronegative element or non metal. Example:

Answer:
1.3×10⁻³ M
Explanation:
Hello,
In this case, given the dissociation reaction of acetic acid:
We can write the law of mass action for it:
Of course, excluding the water as heterogeneous substances are not included. Then, in terms of the change due to the dissociation extent, we are able to rewrite it as shown below:
Thus, via the quadratic equation or solve, we obtain the following solutions:
Obviously, the solution is 0.00133M which match with the hydronium concentration, thus, answer is: 1.3×10⁻³ M in scientific notation.
Regards.
