Answer:
The answer to your question is given below.
Explanation:
To prepare 50mL of 3M HCl, we must calculate the volume of the stock solution needed. This can obtained as follow:
Molarity of stock solution (M1) = 12M
Volume of stock solution needed (V1) =?
Molarity of diluted solution (M2) = 3M
Volume of diluted solution (V2) = 50mL
The volume of the stock solution needed can be obtained by using the dilution formula as shown below:
M1V1 = M2V2
12 x V1 = 3 x 50
Divide both side by 12
V1 = (3 x 50)/12
V1 = 12.5mL
The volume of the stock solution needed is 12.5mL
Therefore, to prepare 50mL of 3M HCl, we must measure 12.5mL of the stock solution i.e 12M HCl and then, add water to the mark in a 1L volumetric flask. Now we can measure out 50mL of the solution.
Formula : ClO3-
Name: Chlorate
Bond : Single (I think)
What is it : usually a gas
Answer:
This is polar
Explanation:
If the arrows are of different lengths, and if they do not balance each other, the molecule is polar.
If the arrangement is asymmetrical, the molecule is polar.
Hope this helped!!!
In a macroscopic object, each particles wave is being absorbed and combined with the waves of the other particles to create one wave for the entire object. Since this object is able to be seen, the wave function immediately collapses.
Anytime you possess anykind of information about the world around us, some wave, somewhere function collapses.
In short, if we can see the object, then it has no wave function.
