Answer: The molar concentration of acetic acid in the vinegar is 0.539 M.
Explanation:
The formula used is:
where,
and are the concentration and volume of base.
and are the concentration and volume of an acid.
Given:
Molar concentration of NaOH = 0.1798 M
Volume of NaOH = 30.01 mL
Volume of acetic acid = 10.0 mL
Now putting all the given values in the above formula, we get:
Thu, the molar concentration of acetic acid in the vinegar is 0.539 M.
Answer:
We would see 5 peaks. 35Cl the lightest and 37Cl2 the heaviest
Explanation:
The chlorine element has two isotopes (35 Cl and 37 Cl), in the mass spectrum we can observe the m/e of the diatomic molecules. Formed by an atom of chlorine 35 and another of chlorine 35. Or one of Cl 35 and one of Cl 37. Or both of Cl 37.
We can also observe the mass of each separately. That is why we would see 5 peaks.
- Cl = 35 <------------------------- lightest
- Cl = 37
- Cl2 = 35 + 35 = 70
- Cl2 = 35 + 37 = 72
- Cl2 = 37 + 37 = 74 <-------- heaviest
A) The bond that will be formed by these elements is : <u>Ionic Bond </u>
B) Group 1 elements Gives up its electron to Group 17 elements
<h3><u /></h3><h3><u>Electronegativity values </u></h3>
From the electronegativity values given in the question group 17 elements with an electronegativity value of 2.99 are more electronegative than group 1 elements with a value of 0.84. Therefore they accept electron transfer from group 1 elements.
The acceptance of electrons from group 17 elements leads to formation of an ionic bond between group 1 and group 17.
Hence we can conclude that the bond that will be formed by these elements is Ionic bond and Group 1 elements gives up its electron to group 17 elements.
