The answers to the question are presented below by letter.
a.) redox reaction - Cl2 is reduced and OH- is oxidized
b.)
c.) acid - base reaction
d.) redox reaction - Fe is oxidized and O2 is reduced
e.) redox reaction - Ca is oxidized and F2 is reduced
<u>Given: </u>
m(g) of Sulfur = 16g
Molar mass of sulfur: 32 g/mol ( from periodic table - atomic mass; mass number or 'A' - the greater number)
Molar Mass of Oxygen: 16 g/mol ( from periodic table from periodic table - atomic mass; mass number or 'A' - the greater number)
<u>Formula used: </u>
n(mol)= m (g) / M (g/mol)
Step One: <u>Write the equation </u>
S + O2 --> SO2
Step Two: <u>Balance the equation ( this one doesn't need balancing) </u>
S + O2 --> SO2
Step Three: <u>Write the molar ratios ( coefficients) </u>
S + O2 --> SO2
1 1 1 <---------molar ratio
Step Four: <u>Find the number of moles of Sulfur (mol) using the formula: </u>
n(mol)= m(g) / M (g/mol)
Substitute 16g in the mass(m) & 32 g/mol in the Molar Mass( g/mol)
n(mol)= 16 (g) / 32 (g/mol)
n(mol) = 0.5 mol of Sulfur
Step Five: <u>Using the molar ratios and the number of moles of Sulfur obtained, cross multiply to find the number of moles of Sulfur dioxide.
</u>( for future reference we don't use O2 because it is in excess, anything in excess we don't use)
S + O2 --> SO2
1 1 1 <---------molar ratio
0.5 x <---------number of moles
1 / 0.5 = 1/x
n ( Sulfur) = n ( sulfur dioxide) since the molar ratio is one to one
n( sulfur dioxide) = 0.5 moles
<span>
</span>Step Six: With<u> the given 0.5 moles for Sulfur dioxide calculated, you can find the mass of sulfur dioxide (SO2). You just have to calculate the Molar Mass of Sulfur and Oxygen by using your periodic table. Formula used:
</u>
n(mol) = m(g) / M(g/mol)
<u>Molar Mass Calculations </u>
M(O) = 16 g/mol
M(S) = 32 g/mol
M(SO2)= 32 + 16(2) = 32 + 32 = 64 g/mol.
<u>Number of moles of Sulfur dioxide calculated: </u>0.5 mol
<u>Plug in the values in their corresponding locations:
</u>
n(mol) = m(g) / M(g/mol)
0.5(mol) = m(g) / 64 ( g/mol)
m(g) = 0.5 x 64
m(g) = 32 g.
<span>FINAL ANSWER: MASS OF SULFUR DIOXIDE = 32 g.

i hope this was of help:) good luck!
I’m sorry but where’s the worksheet lol......
Answer:
True
Explanation:
ion: an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
Answer:
The field-free drift path
Explanation:
In MALDI-TOF, the sample is embedded in a matrix. A laser vaporizes the molecules in the sample with little fragmentation. The gaseous molecules are ionized, accelerated, and sent through a field-free drift path to the detector.
The proteins in the sample have different velocities based on their mass-to-charge ratio.
The fastest ions are those with the smallest m/z ratio.
The field-free drift path increases the separation between the ions, so the smallest ions reach the detector first.
Thus, the ions are separated based on their time of flight through the drift tube.
