What is true about the combustion of water?
miv72 [106K]

Answer:

C

Explanation:

Spontaneous combustion is a type of combustion which occurs by self-heating (increase in temperature due to exothermic internal reactions), followed by thermal runaway (self-heating which rapidly accelerates to high temperatures) and finally, ignition.

I need help on this
sasho [114]

Answer: Y and Z. It's D.

Explanation: W represents evaporation, which is a physical change. X represents dissolving, which is also a physical change. If X and W aren't chemical changes, then Y and Z must be if half of the choices are.

Calculate the mole fraction of each component in a solution of 42 g CH3OH, 35 g of chloroform CHCl3, and 50 g C3H7OH
koban [17]

Considering the definition of mole fraction, the mole fraction of each component in the solution is:

  • CH₃OH: 0.54
  • CHCl₃: 0.118
  • C₃H₇OH: 0.342

<h3>Mole fraction</h3>

The molar fraction is a way of measuring the concentration that expresses the proportion in which a substance is found with respect to the total moles of the solution.

<h3>Mole fraction of each component</h3>

In this case, in first place you should know that the molar mass of each component is:

  • CH₃OH: 32 \frac{g}{mole}
  • CHCl₃: 121.35 \frac{g}{mole}
  • C₃H₇OH: 60 \frac{g}{mole}

Now, the number of moles of each compound can be calculated as:

  • CH₃OH: \frac{42 g}{32\frac{g}{mole}}=  1.3125 moles
  • CHCl₃: \frac{35 g}{121.35\frac{g}{mole}}= 0.2884 moles
  • C₃H₇OH: \frac{50 g}{60\frac{g}{mole}}=  0.8333 moles

So, the total moles of the solution can be calculated as:

Total moles = 1.3125 moles + 0.2884 moles + 0.8333 moles

<u><em>Total moles = 2.4342 moles</em></u>

Finally, the more fraction of each component can be calculated as follow:

  • CH₃OH: \frac{1.3125 moles}{2.4342 moles}= 0.54
  • CHCl₃: \frac{0.2884 moles}{2.4342 moles}= 0.118
  • C₃H₇OH: \frac{0.8333 moles}{2.4342 moles}= 0.342

In summary, the mole fraction of each component in the solution is:

  • CH₃OH: 0.54
  • CHCl₃: 0.118
  • C₃H₇OH: 0.342
