Answer:
p=m/v
p equals density M equals mass and v = volume
Answer:
- blue-black PHYSICAL PROPERTY
- crystalline PHYSICAL PROPERTY
- solid PHYSICAL PROPERTY
- sublimes to a violet-colored gas PHYSICAL PROPERTY
- reacts with aluminum and many other metals CHEMICAL PROPERTY
Explanation:
Chemical properties are visible through chemical reactions, in which the chemical identity changes to form new substances. On the other hand, physical properties are evident without a change in the identity of a substance.

<em>Which of these five properties are physical and which are chemical?</em>
- blue-black PHYSICAL PROPERTY
- crystalline PHYSICAL PROPERTY
- solid PHYSICAL PROPERTY
- sublimes to a violet-colored gas PHYSICAL PROPERTY
- reacts with aluminum and many other metals CHEMICAL PROPERTY
This is true, think of silver, gold, etc— those are heated to make them liquid
An isomer is a compound that differs by another based on either the molecular connectivity or how the atoms are connected to each other in the compound, or by stereochemistry usually.
I believe there are total number of 5 isomers for the compound of C6H14. Hexane.
Answer:
Explanation:
*Since the titration is between the strong acid HCl and the strong base Ca(OH)2, the pH at the equivalent point should be 7. On interpolation, we will obtain that 9.50mL and 9.82 mL of HCl is required to completely neutralized the given Ca(OH)2 solution.
*pH at the equivalence point =7
we know that pH + pOH = 14
Hence pOH= 14-7=7
pOH= -log(OH-)
The concentration of OH-= 10-pH= 1X10-7 M
One reason for the low solubility may be the higher reaction temperature, Another reason is the common ion effect.
