Answer:
A. The balanced equation is given below:
5C + 2SO2 —> CS2 + 4CO
B. 229.5 moles of carbon.
Explanation:
A. Step 1:
The equation for the reaction is given below:
C + SO2 —> CS2 + CO
A. Step 2:
Balancing the equation.
The above equation can be balanced as follow:
There are 2 atoms of S on the right side and 1 atom on the left side. It can be balance by putting 2 in front of SO2 as shown below:
C + 2SO2 —> CS2 + CO
There are 4 atoms of O on the left side and 1 on the right. It can be balance by putting 4 in front of CO as shown below:
C + 2SO2 —> CS2 + 4CO
There are a total of 5 atoms of C on the right side and 1 atom on the left. It can be balance by putting 5 in front of C as shown below:
5C + 2SO2 —> CS2 + 4CO
Now the equation is balanced
B. Determination of the number of moles of carbon needed to produce 45.90 moles of carbon disulfide.
This is illustrated below:
5C + 2SO2 —> CS2 + 4CO
From the balanced equation above,
5 moles of C produced 1 mole of CS2.
Therefore, Xmol of C will produce 45.90 moles of CS2 i.e
Xmol of C = 5 x 45.90
Xmol of C = 229.5 moles
229.5 moles of carbon is needed to produce 45.90 moles of carbon disulfide.
No because observing a physical property of a substance is just observing like color or texture. They don't change. Physical properties do not change the composition of a substance and neither do physical changes.
Answer:
C12h22o11 moles to grams
1 mole is equal to 1 moles C12H22O11, or 342.29648 grams.
hope this helps
Explanation:
The molar mass and the mass of the substance give the moles of the substance. The 10-gram sample of neon (Ne) has the fewest atoms. Thus, option b is correct.
<h3>What are moles?</h3>
Moles of the substance are the ratio of the molar mass and the mass of the substance. The moles of each atom with respect to the Avagadro's number (Nₐ) is given as,
Moles = mass ÷ molar mass
- Moles of carbon (C) = 10 ÷ 12
= 0.83 Nₐ atoms
- Moles of neon (Ne) = 10 ÷ 20
= 0.5 Nₐ atoms
- Moles of fluorine (F) = 10 ÷ 19
= 0.52 Nₐ atoms
- Moles of nitrogen (N) = 10 ÷ 14
= 0.7 Nₐ atoms
- Moles of oxygen (O) = 10 ÷ 16
= 0.63 Nₐ atoms
Therefore, option b. 10 gm neon has the fewest atoms.
