Answer:
pH = -1
Explanation:
A solution of 10 mol·L⁻¹ HCl is very acidic.
HCl is a strong acid, so it dissociates completely in water and
![[\text{H}_{3}\text{O}^{+}] = \text{10 mol/L}](https://tex.z-dn.net/?f=%5B%5Ctext%7BH%7D_%7B3%7D%5Ctext%7BO%7D%5E%7B%2B%7D%5D%20%3D%20%5Ctext%7B10%20mol%2FL%7D)
To get the pH, you take the negative logarithm of the hydronium ion concentration.
So, a pH = -1 represents a very acidic solution.
Answer:
Did you figure out what it was?
Explanation:
The best answer among the following choices would be the fourth option D).
Answer:
A
Explanation:
The law of conservation of mass states that matter can never be created nor destroyed but can be converted from one form to another.
The law of conservation of energy posits that energy cannot be created nor destroyed but can be converted from one form to another.
These laws are the basic laws of existence. Although the laws have been adjusted, they still form the basic principle behind several scientific laws and are responsible for a whole lot of scientific advancements.
While the first law focuses on matter and the content of matter in a body, the second law basically focuses on energy. The second law serves to support the inter convertibility behind the several forms or types of energy.
For example, to do many useful work at home, it is found that energy is converted from its electric form to say heat in an electric iron to press our clothes.
Also, the first law is a fundamental principle useful in the balancing of our chemical equations.
Answer:B
Explanation: the only kind of bond that is not formed by differences in electronegativity is a polar disalent bond because it does not exist, at least to my knowledge.
