A scientific experiment may be set up in order to test the company's claim.
For this, one may send a number of similar packages from different companies and this one. Then, the time taken for the packages to arrive is noted. Afterwards, difference in time of arrival for the similar packages is calculated and then the data obtained is analyzed. If the company's delivery timings are less than the other companies', then their claim is indeed true.
Answer: I think it would be false but im not 1000% sure
The [H₃0⁺] of the solution : 1.778 x 10⁻¹² M
<h3>Further explanation </h3>
pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.
pH = - log [H⁺]
So that the two quantities between pH and [H⁺] are inversely proportional because they are associated with negative values.
A solution whose value is different by n has a difference in the concentration of H⁺ ion of 10ⁿ.
pH of solution = 11.75
the [H₃0⁺] of the solution :
Answer:
A
Explanation:
Opposite charges attract therefore the electrons of one atom would be attracted by the nucleus (which contains protons). This heavily relies on a property called electronegativity. Which deals with the level of attraction a nucleus (the protons in the nucleus) have for electrons of other atoms.
