The first step is to multiply the molarity with the amount of ions in each formula.
For the first pair= (0.1 M)(4)= 0.4 M and (0.2 M)(2)= O.4 M -> There is no net flow.
For the second pair= Since both are the same type of solution, solution A which has a lower concentration will flow to solution B which has a higher concentration.
For the third pair, (0.1 M)(2)= 0.2 M and (0.1 M)(2)= O.2 M. There is no net flow since KBr and NaCL both have 2 ions.
The Ancient Greeks developed astronomy, which they treated as a branch of mathematics, to a highly sophisticated level. The first geometrical, three-dimensional models to explain the apparent motion of the planets were developed in the 4th century BC by Eudoxus of Cnidus and Callippus of Cyzicus.
Answer:
the rock has a greater amount of heat energy which transfers to water causing vaporization.
<h2>
Answer:It always contains certain elements,It always contains elements in definite proportions.,It cannot contain atoms from more than one element.</h2>
Explanation:
The mineral need not occur always in a pure form.On purification we get the exact chemical composition.
The mineral always has a definite chemical composition which means the number of elements and types of elements in the mineral does not change.
Since the mineral has definite composition,the elements in the mineral has definite proportions.
The mineral can be a compound.So,there can be atoms from more than one element.
It keeps the plant upright, and it provides nutrients
