Answers:
1.
The mole ratio of AlCl₃ to Cl₂ is 2 : 3. This means for production of every 2 moles of AlCl₃ 3 moles of Cl₂ is consumed. Hence, if 3 moles of AlCl₃ is produced then Cl₂ consumed is,
= 3 × 3 / 2
= 4.5 moles of Cl₂
2.
Mole ratio of C₃H₈ to CO₂ is 1 : 3.
Hence, 0.5 moles of C₃H₈ will produce 1.5 moles of CO₂.
Also,
At STP one mole of an ideal gas occupied 22.4 L of volume. Hence, 1.5 moles of CO₂ gas will occupy,
Volume = 1.5 mol × 22.4 L/mol
Volume = 33.6 L of CO₂

Answer:
See the answer below
Explanation:
<em>The correct answer would be that the solute particles lower the solvent's vapor pressure, thus requiring a higher temperature to cause boiling.</em>
Dissolving a solute particle in a solvent leads to a decrease in the vapor pressure of the solvent above the resulting solution when compared to the pure solvent. The lower the vapor pressure of a liquid, the higher the temperature required for the liquid to boil and vice versa. Hence, a higher temperature would be needed to boil a solvent with dissolved solutes.
Answer:
we use atom in our sentences all the time
Explanation:
that what i put
5H2O2 + 2KMnO4<span>+ 3H2SO4 = 5O2 + 2MnSO4 + 8H2O + K2SO4
0,145 moles of KMnO4----------in--------1000ml
x moles of KMnO4---------------in------------46ml
x = 0,00667 moles of KMnO4
according to the reaction:
2 moles of KMnO4------------------5 moles of H2O2
0,00667 moles of KMnO4----------------x
x = 0,01668 moles of H2O2
0,01668 moles of H2O2---------in-----------50ml
x moles of H2O2--------------------in----------1000ml
<u>x = 0,334 mol/L H2O2</u></span>
