being +1
Answer:
Number of molecules = 1.8267×10^20
Explanation:
From the question, we can deuced that the gases behave ideally, the we can make use of the ideal gas equation, which is expressed below;
PV = nRT
where
P =pressure
V =volume
n = the number of moles
R is the gas constant equal to 0.0821 L·atm/mol·K
T is the absolute temperature
Given:
P = 6.75 atm;
T = 290.0 k,
; V = 1.07 cm³ = 0.001 L
( 6.75 atm)(0.00107 L) = n(0.0821 L·atm/mol·K)(290K)
n = 3.0335167*10^-4 moles
But there are 6.022×10²³ molecules in 1 mole,
Number of molecules = 1.8267×10^20
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.
