Question

1. Your lab procedure says to measure exactly 100 g of sugar and then add it to the solution. What specific lab equipment would you use to accomplish this task?

A. Graduated cylinder
B. Beaker
C. Bunsen burner
D. Balance or scale

2. Describe the steps you would take to separate a mixture of sugar and sand. What specific properties would you consider as you develop your procedure?
A. Dissolve the mixture in water and filter it. Consider size and solubility.
B. Heat the mixture and condense the water vapor. Consider color and odor.
C. Grind the mixture into a fine powder and use a magnet. Consider density and texture.
D. Freeze the mixture and separate the ice. Consider temperature and taste.

Answer 1

To measure 100 g of sugar, use a balance or scale (option D) . To separate a sugar and sand mixture, dissolve the mixture in water, filter it to remove the sand, and then evaporate the water to reclaim the sugar.Thus, the correct answer is option A.

Step-by-step explanation:

Lab Equipment for Measuring Sugar

To measure exactly 100 g of sugar and add it to the solution as per the lab procedure, you would use a balance or scale (Option D). A balance or scale is the appropriate tool for measuring precise amounts of solid substances like sugar in a laboratory setting.

Separating a Mixture of Sugar and Sand

To separate a mixture of sugar and sand, you should consider the properties of solubility and size. The correct steps to achieve this would be:

1. Dissolve the mixture in water, which allows the sugar to dissolve while the sand does not.
2. Filter the solution to separate the sand from the dissolved sugar water.
3. Evaporate the water to recover the dissolved sugar.

This process makes use of the fact that sugar is soluble in water while sand is not, which answers option A.
