Answer:
Will group 2 elements lose electrons to bond with nonmetals in group 17 in a
1:2 ratio?
Explanation:
Metals are electropositive in nature. This means that they loose electrons. Thus, metals form ionic bonds by loosing electrons to non metals.
Elements of group 2 have a valency of 2 while those of group 17 has a valency of 1 so the ratio in which group 2 elements bond with elements of group 17 is 1:2. Hence the answer.
Noble gases are all elements in column 18. aka far right

The ratio of buffer C₂H₃O₂ /HC₂H₃O₂ must you use are1:0.199 or 10:2
the ratio of buffer C₂H₃O₂ /HC₂H₃O₂ can be calculate using the Henderson-Hasselbalch Equation which relates the pH to the measure of acidity pKa. The equation is given as:
pH = pKa + log ([base]/[acid]
Where,
[base] = concentration of C₂H₃O₂in molarity or moles
[acid] = concentration of HC₂H₃O₂ in molarity or moles
For the sake of easy calculation, allow us to assume that:
[base] =1
[acid] = x
Therefore using equation 1,
5.44 = 4.74 + log (1 / x)
log [base / acid] = 0.7
1 / x = 5.0118
x = 0.199
The required ratio of buffer C₂H₃O₂ /HC₂H₃O₂ is 1:0.199 or 10:2
