Can someon me, i can give you a 25 points

1. option D titanium because metallic properties increases down the group .

2. option A potassium has the least malleable character due to top element of the group .

4. Option D metallic trends are increase from right to left and top to bottom

5. Option A Conductivity will be the main concern for the mobility of free electrons during cooking

7. Option B

Explanation:

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
