Answer:

B, C, E  

Explanation:

What you are trying to do is increase the solute/solvent ratio.

B. Adding more solute increases the value of the numerator, so it increases the ratio.

C. Boiling away some solvent decreases the value of the denominator, so it increases the ratio.

E. Heating the solution so more solute dissolves increases the value of the numerator, so it increases the ratio.

A is wrong. Adding more solvent makes a more dilute solution.

D is wrong. The solvent dissolves the solute.

Given the balanced combustion reaction: 2C2H6 + 7O2 --> 4CO2 + 6H2O
Tatiana [17]

Answer:

2C2H6(g) + 7O2(g) ==> 4CO2(g) + 6H2O(g)

One way to find the limiting reactant is to divide the moles of reactant by the corresponding coefficient in the balanced equation and whichever is less is limiting.

For C2H6 we have 2 moles / 2 = 1

For O2 we have 8 moles / 7 = 1.14

Explanation:

If a reaction mixture contains 8 moles of O2(g) with 2 moles of C2H6(g),which reactant is the limiting reactqnt and what is the mass (in grams) remaining of the reactant in excess?

Why the standard enthalpy change of hydration of copper sulphate cannot be measured directly ?
Juliette [100K]

It is difficult to measure the enthalpy change of hydration accurately in a direct way because the hydration process can't be controlled directly. Instead, anhydrous and hydrated copper(II) sulfate can be dissolved in water. Each 'route' produces a solution of hydrated copper(II) sulfate.

Reactions which do not continue to completion are called _____reactions
SIZIF [17.4K]
I think the answer is reversible. Reversible reaction is a kind of reaction which can react in both direction at the same time. And when the both side reactions get the same speed, the reaction is at a equilibrium state.
