Answer: <em>
pH=2.25 </em></h3>
Explanation:
monochloroacetic acid also means: chloroacetic acid
pKa of monochloroacetic acid= 1.4 x 10^-3 (I believe this should have been given in the problem or perhaps in the textbook)
Formula: pH= pKa + log ( some number in M)
pH= -log (1.4 x 10^-3) + log (0.25M)= 2.85 + -0.602= 2.25
pH= 2.25
The appropriate number of bonds around each carbon atom are four covalent bonds
Please note that carbon has four valence electrons in its outermost shell
<h3>What is an element?</h3>
An element is a substance which cannot be split into simpler forms by an ordinary chemical process. This simply goes to say that elements are substances which cannot be decomposed into simpler substances by ordinary chemical reactions.
An atom is the smallest unit or part of an element which can take part in a chemical reaction.
On a general note, elements are classified as thus:
- Metals, non-metal, and metalloid.
- The extreme left side elements in the periodic table are metals, for example, aluminum, sodium, calcium, caesium, etc.
- However, elements on the right side are generally referred to as non-metals, carbon, chlorine, oxygen,
So therefore, the appropriate number of bonds around each carbon atom are four covalent bonds

Answer:
15.95 g
Explanation:
Calculation of the moles of sulfur as:-
Mass = 3.5 g
Molar mass of sulfur = 32.065 g/mol
The formula for the calculation of moles is shown below:
Thus,
From the reaction,

1 mole of sulfur on reaction forms 1 mole of sulfur hexafluoride
0.1092 mole of sulfur on reaction forms 0.1092 mole of sulfur hexafluoride
Molar mass of sulfur hexafluoride = 146.06 g/mol
Mass= Moles*Molar mass = 0.1092*146.06 g = 15.95 g
<u>15.95 g is the maximum amount of
that can be produced from the reaction of 3.5 g of sulfur with of fluorine.</u>
