Answer:
The amount of NaF produced is doubled.
(d) is correct option.
Explanation:
Given that,
A 2 mole sample of F₂ reacts with excess NaOH according to the equation.
The balance equation is

If the reaction is repeated with excess NaOH but with 1 mole of F₂
The balance equation is

Hence, The amount of NaF produced is doubled.
(d) is correct option.
The correct answer of the given question above about acetylsalicylic acid would be t<span>he C double bonds with O and the ring structure are </span>rigid<span>. The parts of acetylsalicylic acid that are rigid are the C double bonds with O and the ring structure. Hope this answer helps. </span>
Isoelectronic means equal number of electrons.
O+ is formed when the atom of O loses 1 electron.
The number of electrons of neutral O atom equals its number of protons.
Number of protons identifies the atomic number and position of the element in the periodic table.
The positon of O in the periodic table is A = 8, so it has 8 electrons and O+ has 8 - 1 = 7 electrons.
The neutral atom with one electron less than O is of the element to the left of O in the periodic table (A = 7). That element is N.
Therefore, the neutral atom isoelectronic with O+ is N (both have 7 electrons).
Calcium will loose one electron. Fluorine will gain one electron. Lithium will loose one electron. Argon will not loose any because it already has a full valence level. Aluminium will loose 3 electrons.
Answer:
Approximately 0.126 M
Explanation:
For the calculation of the dilution you take into account the moles of NaOH in the 42.1mL of the original solution and you use the new volume of 342.1 mL:

The standardization is necessary because a beaker is not not an instrument used to measure volumes and the marks on it only give an estimate of the volume of the solution, they are used to contain solutions and carry reactions among other things. If you would have measured the water with a graduated cylinder (an instrument designed to measure volumes) the standardization wouldnt be that necessary.
