Answer:- 55 g of LiCl are required to make 2.0 L of 0.65 M solution.
Solution:- Given-
molarity of the solution = 0.65M
Volume of solution = 2.0 L
molarity of solution = 
It could be arranged as...
moles of solute = molarity x volume of solution
moles of solute = 0.65 x 2.0 = 1.3 moles
Molar mass of LiCl is 42.39 g/mol.
So, mass of LiCl required = 1.3 mol x 42.39g/mol = 55 g

Answer:
Increased
Explanation:
We know that the higher the temperature the higher the rate of reaction. This implies that as the temperature is increased, a reaction tends to proceed faster.
This follows from the collision theory, the higher the temperature, the higher the energy of the reacting particles hence they collide with each other faster and more effectively.
Thus the rate of reaction( or reaction time) for the carton of milk on the counter was increased.
Answer:
En lugar de utilizar las ya conocidas unidades de concentración, para la solubilidad es más común emplear la siguiente: Medimos la solubilidad como la cantidad de gramos del soluto que podemos disolver en 100 gramos de disolvente.
Explanation:
<span>The type of map that shows the type and age of
rocks in an area is called a Geologic Map. A geologic map is a special-purpose
map that represents the distribution of diverse types of rocks, as well as
locations of different geologic structures such as faults and folds. This map
is the main source of information for various aspects of land-use planning,
especially in the placement of transportation systems and buildings. Although
they are typically depicted as two-dimensional, they can also be illustrated in
its third or fourth dimension depending on the type of information needed to be
taken. </span>
