Answer:
Basic
Explanation:
The pH scale is measured from 0 to 14.
At the pH scale of 7, a solution is neutral.
Any solution above 7 is basic.
Any solution below 7 is acidic.
Because you have been given the hydronium concentration [H₃O⁺], you can find the pH of the solution using the following formula:
pH = -log[H₃O⁺]
pH = -log(6.0 x 10⁻¹²)
pH = 11.22
As you can see, the solution must be basic because the pH lies within the basic range.
Answer:
Earth is not flat because the spheroidical shape provides a more effective shape in terms of exposed surface area for absorbing and radiating radiation, and also for a relatively more uniform gravity pull on different points on its surface which might not be so for a flat surface.
You live in your country, not mine because you have evolved over time to be more adapted to living in your own kind of envoirment. Members of a certain species (like you and me as humans) have been spread to maximize the survivability of their species compared to if they were clustered to a particular place.
Answer:
we need to look at what actually happens to reactant molecules during a chemical. in order for the reaction to take place , some or all of the chemical bonds in the reactants must be broken so that the new bonds, those of the products , can form.
A. potential energy.
It can't be any of the above questions. When the automobile burns gas it converts the potential energy into chemical energy which intern gets converted into mechanical energy and then into kinetic energy.
I would have thought it would be Chemical potential energy, which is referring to the energy between the bonds in the molecule.
