Explanation:
Since [H+] [OH-] =10^(-14)
[H+] = (10^-14) / (1.4×10^-10)
Answer:
Will the electronegativity of barium be larger or smaller than that of strontium? Explain. EN of Ba (0.89) is smaller than EN of Sr (0.95). Because of larger size and more inner core e- shielding, Barium will more readily share its valence electron in the 6s sublevel than Sr will share it valence e- in the 5s sublevel.

Answer:
3 g/mL
Explanation:
Density is mass divided by volume (g/mL).
Mass of rock = 12.5
Volume of rock = 24-20 = 4mL
Density of rock = 12.5g/ 4mL = 3.125 g/mL
Round to the lowest number of significant figures which is 1 to get 3 g/mL
