Answer:
Option C. Ksp for PbCl₂
Explanation:
The equilibrium constant that is established between a solid and its ions in a saturated solution is what is known as Ksp (solubility product). It is an equilibrium constant based on concentrations.
The concentrations must be equilibrium, that is, concentrations of the ions in a saturated solution. To be sure of such saturation it is convenient to form a precipitate.
The smaller the Kps, the more insoluble the salt
Answer:
The answer is given below
Explanation:
When electronegativity difference arises between the bonded atoms, then a molecule is polar.
When electros are shared equally between the bonded atoms or when the polar bonds in a bigger molecule cancels out each other, then a a molucule is non polar.
(a) 50% isopropanol/H2O,--- 2 (second least polar)
(b) 25% isopropanol/H2O,----- 3 (third least polar)
(c) pure water----- is 4 (most polar)
(d) 70% isopropanol/H2O. 1 (least polar)
Answer:
model of mountain formation
Explanation:
The formation of mountains takes millions of years. This formation of mountains involves so much processes that do not occur quickly.
Hence, a model that can adequately show something that happens very slowly is the model for the formation of mountains.
To evaluate the accuracy of a measurement, the measured value must be compared to the correct value. To evaluate the precision of a measurement, you must compare the values of two or more repeated measurements.
Because ecosystems don't change over one day, they change over a long period of time. Plus, something that happens may be because of more than just one change.
