Calculate the amount of miles of HCI is needed to make 500.0 mL of a 0.200M solution
frozen [14]

Answer: 0.4 moles

Explanation:

Given that:

Amount of moles of HCI = Z (let unknown value be Z)

Volume of HCl = 500.0 mL

Convert 500.0 mL to liters

If 1000ml = 1L

500.0 mL = (500.0 mL/1000mL) = 0.5L

Molarity of HCl solution = 0.200M

Recall that molarity of a solution is obtained by dividing the amount of moles by volume in liters

i.e Molarity = Amount in moles/volume

0.200M = Z x 0.5L

Z = 0.200M / 0.5L

Z = 0.4 moles

Thus, 0.4 moles of HCl is needed to make the solution

You have 500 mL of 5 M HCI already made. You need to dilute the solution to 1 M HCI. How much water will you need to add?
Strike441 [17]

Answer:

a. 2500 ml of water is needed

Explanation:

V1C1=V2C2

(500)(5)=(1)V2

2500/1=V2

2500 = v2

Click the "draw structure" button to launch the drawing utility. under certain reaction conditions, 2,3−dibromobutane reacts wit
REY [17]

Answer:

Explanation:

According to this. Let's analize the possible products a, b and c.

First, the problem states that we have 2 eq. of base, For this case, let's assume it's KOH. Now, As we are doing a reaction with base, means that this reaction can only take places under conditions of SN2 and E2, a fast reaction that is taking place in only 1 step.

With this in mind, let's analyze product a. This states that it has two sp hybridized carbon, in other words, a triple bond between two carbons. So the product is with no doubt, an alkyne.

Product b has only one sp hybridized carbon, which means that this carbon should cannot be an alkyne because we need two carbon atoms. The only way to have one atom of C sp hybridized, is with two double bonds, so product b would have to a alkene with two double bonds.

Product c do not have sp hybridized carbon, therefore, it only has two double bonds in two different Carbon atoms, so it's another alkene with two double bonds, but in two different atoms of carbon.

Picture attached show the product a, b and c. Hope this can help

the atom was thought to be indivisible. Explain the significance of Thomson's concept of the electron.
Ludmilka [50]

Answer:

Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson's plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged "soup.
