[H+][OH-] = 1x10-14 = Kw (Memorize this relationship)
(2.70x10-2)[OH-] = 1x10-14
[OH-] = 1x10-14/2.70x10-2
[OH-] = 3.70x10-13 M (assuming you ignore the autoionization of H2O)
Answer:
The process of forming the iron - rich core, the low density crust which is also rich in silicon, oxygen, aluminum, and the intermediate density mantle rich in silicon, oxygen, and magnesium is called the differentiation. Thus, the answer to this item is letter A.
Explanation:
Answer:
Methane
Explanation:
Methane is a synthetic compound with the substance recipe CH4. It is a gathering 14 hydride and the most straightforward alkane, and is the principle constituent of petroleum gas
The energy to vaporize the water at its normal boilng point (100°C) is the vaporization latent heat.
The vaporization latent heat of water is 2257 J/ g (you can find it in a textbook, tables or internet).
So, with 955 kJ you can vaporize this amount of water:
[995 kJ * 1000J/kJ ] / 2557 J /g = 389.13 g
Use the density to convert to volume: D = M / V => V = M / D
V = 389.13 g / 1.00 g / ml = 389.13 ml, which rounded to 3 significant figures is 389 ml
Answer: 389 ml
