Answer:
Density=1.006 g/cm^3 .
Detailed explanation in screenshot attached below
Explanation:
Answer:
A - 8
B - 8
C - O
D - 26
E - 30
F - Fe
Explanation:
Use these things:
1. A = Z + N,
where A - mass number,
Z - atomic number,
N - number of neutrons
2. atomic number = number of protons
Phenolphthalein is not a good indicator to use for a titration for a solution that has a ph of 6.0 at the equivalence point because the color change of the solution at this pH level is not sharp. It changes the color of the solution to pink starting from pH 8.3 to 10. A pH level lower than 8.3 would only show a colorless solution. Thus, you would not be able to distinguish whether the solution has reached its equivalence point at pH 6.0. It is best to use this indicator for a system that is using a strong base titrated with a weak acid.
Because it has a smaller atomic number. Elements are not lined up according to the higher average atomic mass, but rather according to the higher atomic number.
It breaks small pieces off over time until the rock is absolutely gone.
