i believe it's c but I'm not one hundred percent sure
Explanation:
Answer:
Copper is a metal made up of copper atoms closely packed together. As a result, the electrons can move freely through the metal. For this reason, they are known as free electrons. They are also known as conduction electrons because they help copper be a good conductor of heat and electricity.
Explanation:
A period is horizontal; the elements gain 1 proton for each space moving left to right.
A group is vertical; the elements in each group have the same number of electrons in the valence shell(outer orbital).
The volume of NaOH needed for the titration is calculated by equating the number of moles of KHP and NAOH.
(1) number of moles of KHP:
n = mass of KHP / molar mass of KHP
Substituting,
n = 0.061 g / (204.22 g/mol) = 2.987 x 10⁻⁴ moles KHP
(2) number of moles of NaOH
n = (volume NaOH in L)(molarity of NaOH)
n = V x 0.01
Equating,
0.01V = 2.987 x 10⁻⁴
The value of V from the equation is 0.0299L of NaOH.
Converting the value to mL will give us the answer of 29.87 mL.
