It should have 10 electrons
The fluoride ion in the reaction has been the acceptor of the hydrogen. Thus, the fluoride ion has been the Brønsted Lowry base.
<h3 /><h3>What is the Brønsted Lowry acid and base concept?</h3>
The Brønsted Lowry acid and base concept can be described based on the proton acceptor and donor. The Brønsted Lowry acid has been the proton donor, and the Brønsted Lowry base has been the proton acceptor.
The Arrhenius concept is based on hydrogen and hydroxide donors. The Arrhenius base has been the hydroxide donor, and the Arrhenius acid has been the hydrogen donor.
Since the fluoride ion has been the proton acceptor in the reaction, it has been the Brønsted Lowry base.

Answer: Question 3
Group 14, Period 3 is a metalloid
Explanation: Question 3
The element in group 14, period 3 on the periodic table is Si. Metalloids are elements which share both non-metallic and metallic characteristics.
Answer:
potassium hydrogen phthalate KHP MOLAR MASS = 204.233 glmol
to get 1000 ml
Molar concentration = Mass concentration/Molar Mass
mass concentration = molar concentration x molar mass
mass concentration=0.1 M,
molar mass= 204.233 g/mol
so to get 1L
mass conc = 204.233 x 0.1
= 20.4233g for 1L or 1000 ml
to get 6.00 ml
if 20.4233g is for 1000ml
then to 6.00 ml
= 20.4233 x 6 / 1000
= 0.123g for 6.00 ml
according to the equation below
NaOH(aq) + KHC8H4O4(aq) --> KNaC8H4O4(aq) + H2O(l)
number of moles of NaOH is equal to that of KHP
so the same amount will be needed too, which is
= 0.123g
