Answer:
d = 7.9 g/mL
Explanation:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
Given data:
Mass of brown metal = 14.2 g
Volume = 1.8 mL
Density = ?
Solution:
d = m/v
d = 14.2 g/1.8 mL
d = 7.9 g/mL
Cups and glasses are taking too long to air dry this could be caused by the bad ventilation system.
Bad ventilation, or the lack of air flow.
To make sure that no moisture is left on them.
If the moisture or some water drops are left on glasses or cups.
These water drops leave a strange mark and causes a smell in dishes.
Other reasons of cups and glasses are taking too long to dry than the improper working of ventilation can be:
Humidity in Air, Improper Heat, and use of Soap
Humidity in Air, causes high moisture in air that results in the delay in drying of dishes that may lead to even bad smell and bacterial infection on cups and glasses causing bad health.

The answer is c and possibly a I don't know why im here i dont know what this is so bye...
Answer: Rotation occurs at single bonds that are sigma bonds. Rotational barrier is the amount of activation energy required to covert rotamer to another by rotation that occurs around the sigma bond(C-C single bond). Due to the presence of steric hindrance that is the nonbonding interaction effects the reactivity of ions and molecules, activation energy increases. So the rotational barrier in butenyl cation is high.
It is greater than the total mass of the products
