Answer:
White spirits (used in lighter fluid), turpentine and Kerosene can cope with fat/oil stains, tar/asphalt and some adhesives. Many pre-wash spot treatments contain solvents. Mild Acids - such as white vinegar, cream of tartar or lemon juice help remove rust and some food stains.

Answer: C (Sugar's tendency to dissolve in water)
Answer:
When your cooking, or baking a cake. For example, If you bake a cake you are adding ingredients to the cake. When you still the cake into the oven all the ingredients are reacting to each other, causing a chemical reaction.
Explanation:
Answer : The incorrect option is, (d) The reactant that was the smallest given mass is the limiting reagent.
Explanation :
Limiting reagent : It is the reagent that is completely consumed in the chemical reaction when the chemical reaction is complete. No amount is left after the reaction is complete. The amount of product obtained is determined by the limiting reagent. A balanced equation is necessary to determine which reactant is limiting reagent.
Excess reagent : It is the reagent that are not completely consumed in the chemical reaction. That means the reagent is in excess amount. Some amount of the excess reagent is left over after the reaction is complete.
From this we conclude that the options, A, B and C are correct. While the option D is incorrect.
Option D is incorrect because it is not necessary the reactant that was the smallest given mass is the limiting reagent but it is judge by the number of moles present in the reaction.
Hence, the incorrect option is, (d)
Answer: 0.83mol/m3
Explanation:
Number of mole = 2.5 mmol = 0.0025mol
Recall
1L = 0.001m3
Therefore 3L = 3x0.001 = 0.003m3
0.003m3 contains 0.0025mol
Therefore, 1m3 will contain = 0.0025/0.003 = 0.83mol
The concentration in mol/m3 is 0.83mol/m3
