Answer:
The molarity of a sugar solution is 2 M.
Explanation:
Molarity is a concentration measure that expresses the moles of solute per liter of solution. In this case it is calculated with the simple rule of three:
4 L of solution--------8 moles of sugar
1 L of solution ------x= (1 L of solution x 8 moles of sugar)/4 L of solution
x=2 moles of sugar---> <em>The solution is 2M</em>
Answer:
The design of experiments (DOE, DOX, or experimental design) is the design of any task that aims to describe and explain the variation of information under conditions that are hypothesized to reflect the variation. The term is generally associated with experiments in which the design introduces conditions that directly affect the variation, but may also refer to the design of quasi-experiments, in which natural conditions that influence the variation are selected for observation.
Explanation:
Answer:
neutrons are uncharged and electrons are negatively charged
Answer: a) 0.0144mol/L
b) 
Explanation:
Solubility product is defined as the equilibrium constant in which a solid ionic compound is dissolved to produce its ions in solution. It is represented as 
The equation for the ionization of the 
is given as:
We are given:
Solubility of = 
Molar Solubility of = 
1 mole of gives 1 mole of 
and 2 moles of 
ions
Solubility product of = ![[Pb^{2+}][Cl^-]^2](https://tex.z-dn.net/?f=%5BPb%5E%7B2%2B%7D%5D%5BCl%5E-%5D%5E2)
![K_{sp}=[0.0144][2\times 0.0144]^2](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D%5B0.0144%5D%5B2%5Ctimes%200.0144%5D%5E2)
Thus the solubility product constant is
Answer: I kin tommyinnit
Red foxes is the top one
White spruces and willows are the producers
the bottom one is Lynx and hawk.
