Answer:
Density of the object = 1.67 g/ml (≅1.7 g/ml)
Explanation:
<u>Given:</u>
Mass of the object, M = 14.01 g
Initial volume of water in the cylinder, V1 = 25.2 ml
Volume of water after the object is placed in the cylinder, V2 = 33.6 ml
<u>To determine</u>
The density D of the object
<u>Explanation:</u>
Density (D) of a substance is the mass (M) occupied by the substance in a given volume (V) i.e.
![D = \frac{M}{V}](https://tex.z-dn.net/?f=D%20%3D%20%5Cfrac%7BM%7D%7BV%7D)
In this case:
M = 14.01 g
The volume V of the substance = V2-V1 = 33.6-25.2 = 8.4 ml
![D = \frac{14.01 g}{8.4 ml} = 1.67 g/ml](https://tex.z-dn.net/?f=D%20%3D%20%5Cfrac%7B14.01%20g%7D%7B8.4%20ml%7D%20%3D%201.67%20g%2Fml)
Answer: OPTION, D
Explanation:
It is an example for ionic salt and has Calcium ion and sulfate ion.
Hence it's name is Calcium sulfate.
Calcium sulfoxide does not exist.
Calcium sulfite has CaSO3.
Answer: C. Biochemistry
Explanation:
Merriam-Webster Dictionary defines Biochemistry as:
<em>"chemistry that deals with the chemical compounds and processes occurring in organisms"</em>
