Answer:
1. density = 0.89 g/cm3
2. Yes is possible to identify the liquid
3. ethanolamine
Explanation:
<u>Data:</u>
mass = 682 g
volume = 0.767 L = 767 mL or cm3
1.
To calculate the density of the liquid it is necessary to know that the density formula is:
The data obtained is replaced in the formula:
2.
With the given data it is possible to identify the liquid, this because the density value is a basic property of each liquid.
3.
It is possible to determine what liquid it is, since when comparing the value obtained with those reported in the collection of Material Safety Data Sheets (MSOS), the value that agrees is that of ethanolamine.

The process which can be used to separate salt from the sand is leaching since salt is soluble in water thus it goes to the water leaving the sand behind. To separate salt from the water, you can allow the water to evaporate where it undergoes a phase change.
1 - Chemistry is a branch of science focusing on elements, reactions, and chemicals.
2 - We study chemistry to learn more about these chemicals and elements and to discover new chemicals as well as to answer questions in life about reactions.
3 - Chemistry relates to our life in various ways, from the chemicals we inhale to the basic reactions in cooking and baking.
4 - The main branches of Chemistry are Physical, analytical, biochemistry, organic and inorganic chemistry.
Hope this helps!
