Answer:
Potassium (K) and Lithium (Li) for the fist one i cant see the second
Explanation:
Yes, but they are tubular organs and like all other organs are made up of tissues
Always remember that pH + pOH = 14
Here, you have a pOH of 11.24, so you replace it in the equation, and u get:
pH + 11.24 = 14
Then, You move 11.24 to the other part. and moving from a part to another change the sign of the equation. And you get:
pH = 14 - 11.24 = 2.76
So, the pH of a solution that has a pOH of 11.24 is pH = 2.76
Hope this Helps :)
1 is D - double-replacements do not make solid metals
2 is A - to have complete combustion the original compound must ONLY have C, H and O
3 is B - the elemental Mg replaces the H in the HCl
Explanation:
in the presence of excess oxygen methane burns to prduce carbon (iv) oxide and water ....this is called complete combustion...
