Answer:
25 mol
Explanation:
2C₈H₁₈ + 25O₂ ⟶ 16CO₂ + 18H₂O
The equation tells us that 25 mol O₂ generate 18 mol H₂O.
Answer:
- <u><em>Sodium fluoride</em></u>
Explanation:
A <em>solution </em>is constituted by two parts: the solute and the solvent (there may be more than 1 solute and more than 1 solvent, but that is not the key of the answer).
<em>Solute</em> is the substace that is dissolved and it is in less amount than the solvent.
<em>Solvent</em> is the substance that can dissolve the solute and it is a greater amount than the solute.
In the given solution:
- <em>sodium fluoride</em>, <em>85.0 mL</em>, is the solute,
- <em>water</em>, <em>350.0 mL</em> is the solvent, and
- the mixture of both substances is the solution.
Aluminum sulfide is Al₂S₃, which shows that there are 3
sulfur atoms per formula unit.
In one mole there is Avogadro’s number of atoms and Avogadro’s
number = 6.02 x 10²³
In 1.10 mole = 1.10 x 6.02x10²³ = 6.62 x 10²³ formula units
Now multiply with 3 to get number of sulfur atoms present in
1.10 mol of Aluminum sulfide;
3 x 6.62x10²³ = 1.99 x 10²⁴
So, the answer is 1.99 x 10²⁴ sulfur atoms.
<span>oxidizing agent removes an electron from other specie
the oxidizing agents are reduced due to loss of electrons
</span><span> F2 is reduced from neutral state to 1- so it act as an oxidizing agent
</span>so correct option is A
hope it helps
