Answer:

Acetone and water is immiscible

Acetone and hexane is miscible

Explanation:

Acetone with the chemical formula (CH3)2CO, is a nonpolar organic liquid that will mix easily. Hexane, an aliphatic hydrocarbon with 6 carbon atoms represented as C6H14 is also nonpolar. Thus, acetone and hexane would mixed completely to form a clear solution in the test tube.

On the other hand, acetone and water is immiscible (do not mix) since water, H2O, is a polar compound. And polar compounds do not react or dissolve nonpolar compounds (acetone). Usually, a mixture of acetone and water will be seen to form two distinct layers in the test tube.

What mass of co was used up in the reaction with an excess of oxygen gas if 24.7 g of carbon dioxide is formed
sleet_krkn [62]
Balance Chemical Equation of this reaction is,

                                      2 CO  +  O₂   →   2CO₂

Acc. to this reaction,

88 g (2 mole) of CO₂ was produced when  =  56 g (2 mole)of CO was reacted
So, 
24.7 g of CO₂ will be produced by reacting =  X g of CO

Solving for X,

                                    X  =  (56 g × 24.7 g) ÷ 88 g

                                    X  =  2.26 g ÷ 88 g

                                    X  =  0.0257 g of CO

Result:
           
0.0257 g of CO is required to be reacted with excess of O₂ to produce 24.7 g of CO₂.
