Answer:
40.68kPa
Explanation:
The remaining part of the question is requesting to calculate the pressure (p2) after increase in volume.
Data;
V1 = 21.3mL
P1 = 98.8 kPa
V2 = 52.7 mL
P2 = ?
Using Boyle's law,
PV = K
P1V1 = P2V2
98.8 * 21.7 = p2 * 52.7
P2 = 2143.96 / 52.7
P2 = 40.68 kPa
Note I didn't convert the values since they all have the same unit.
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.

Answer:
When zinc is added to copper sulphate (CUSO4) solution due to more reactivity of zinc, cooper is replaced by the zinc and forms zinc sulphate. During the process, the colour of the solution changes from blue to colourless.
