Answer:
A pH less than 7 is an acid, with number 1 indicating stronger acids
Explanation:
The pH scale has a range of 1 to 14. The following has been concluded on the pH scale:
1. Between 1 and 6 indicates an acid solution.
2. 7 indicates a neutral solution
3. Between 8 and 14 indicates an alkaline or basic solution.
Now with these information, we can answer the above questions as follow:
A pH less than 7 is an acid, with number 1 indicating stronger acids

Answer:
By weight they have the same mass, but the number of atoms is different
Explanation:
Answer:
The concentration of H⁺ in stomach acid is approximately ten times greater than that of lemon juice.
Explanation:
The H⁺ concentration of a solution is exponentially related to its pH value:
![\rm [H^{+}] = 10^{-pH}](https://tex.z-dn.net/?f=%5Crm%20%5BH%5E%7B%2B%7D%5D%20%3D%2010%5E%7B-pH%7D)
.
For lemon juice:
![\rm [H^{+}] = 10^{-2.0} = 0.01\; M](https://tex.z-dn.net/?f=%5Crm%20%5BH%5E%7B%2B%7D%5D%20%3D%2010%5E%7B-2.0%7D%20%3D%200.01%5C%3B%20M)
.
For stomach acid:
![\rm [H^{+}] = 10^{-1.0} = 0.1\; M](https://tex.z-dn.net/?f=%5Crm%20%5BH%5E%7B%2B%7D%5D%20%3D%2010%5E%7B-1.0%7D%20%3D%200.1%5C%3B%20M)
.
Thus, the concentration of H⁺ in stomach acid is approximately ten times greater than that of lemon juice.
Answer:
Diffusion of Innovation (DOI) Theory, developed by E.M. Rogers in 1962, is one of the oldest social science theories. It originated in communication to explain how, over time, an idea or product gains momentum and diffuses (or spreads) through a specific population or social system
Explanation:
steps of divusion if you need it are
Knowledge. The first step in the diffusion of innovation is knowledge. ...
Persuasion. Persuasion is the point at which the prospective adopter is open to the idea of purchase. ...
Decision. Eventually the would-be adopter must make a decision. ...
Implementation. ...
Confirmation.
