Answer:
0.2M NaOh
Explanation:
there are 0.2 mol of NaOH in 8.0 g. (8.0/40) =0.2. Molarity = mol/L = 0.2M.
Answer:
b) Every experienced cooks at home tend not to use recipes, instead based entirely upon their knowledge of cooking technique.
Explanation:
This is because even the most experienced cooks might make a mistake, so having a recipe where they can follow is better than just use their knowledge. If his or her knowledge has a mistake it might create a big consequence.
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.
