Answer:
B.
Explanation:
it's B because 4 x 2 is 8 and we all know 8 x 8 is 64. So the answer is B.
Because that is the ideal gas at STP.
Answer:
mixture
Explanation:
The properties of the components of substance are different. One component has magnetic properties, another does not. So, we have at least 2 individual substances that were mixed together. So, we have a mixture.
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.
