Answer:
Question 4. <u>True</u> - As when water is boiled the water molecules expand and this exapansion leads more amount of salt that can be dissolved in it.
Question 5. <u>True</u> - As solubility curves show how the solubility of a solute in a given solvent changes as the temperature changes.
Question 6. <u>True</u> - As the solubility of KNO3 increases more than six times between 0 and 50 degrees C.
Question 7. <u>False</u> - As the solubility curve indicates changes in temperature for solubility of substances.
Answer:
A synthesis reaction.
Explanation:
A synthesis reaction takes place when two elements are combined to form one compound.
Answer:
E. 5.049
Explanation:
Multiply the concentration by volume (in liters) first to get moles of NaOH. Then multiply by the molar mass of NaOH to convert to grams.
0.18 M • 0.7000 L = 0.126 mol NaOH
0.126 mol • 39.997 g/mol = 5.040 g --> The closest answer seems to be e. 5.049 g
