The correct option is C.
When glucose is stirred into water to form a solution, then glucose is the SOLUTE and water is the SOLVENT. A solute refers to a substance that is dissolved in a solvent. For instance, salt is the solute that is dissolved in salt solution. A solvent on the other hand refers to the liquid into which the solute was dissolved. For instance, in the case of salt solution, water is the solvent, because it is used to dissolve the salt.
M=120.0 g/mol
M(SiO₂)=A(Si) + 2A(O)
M(SiO₂)=28+2*16=60 g/mol
N=M/M(SiO₂)
N=120.0/60=2
(SiO₂)₂ or Si₂O₄
Answer:

Now, 500 gallons of propane are available and equivalent to the following amount in moles (propane's molar mass is 44g/mol):
Finally, the time for the 4 burners to burn the 500 gallons of propane result in:
Best regards.
Answer:
The mixture of B and C will melt as 130 - 139 ºC.
Explanation:
If the melting point (130 - 139 ºC) of a mixture of A and B is lower than the pure substances that is 149 - 150 ºC that means that one of these susbtances is an impurity because reduces the melting point.
If the melting point of the mixture of A and C is the same as the pure substances, we can deduce that they are the same substances, also because the melting point when a substance is pure is just 1 or 2 ºC like in this case.
So in a Mixture of B and C is going to be like the first case of the mixture among A and B, because the B substance is the impurity.
