If 5 ml of 0.5 M NaOH is added to 20 ml each of Buffer b and buffer c. Both of the buffers' pHs won't change since a buffer has a property that if it is added to another solution, acidic or basic, its pH won't change.
Answer:
The common thing among the three states of matter is - They are made up of small tiny particles. They have a particular mass and can occupy space . This three states have volume in it . The atoms of this three states have force of attractions between them .
Explanation:
hope this helps <3
True. Because they are white we know that they reflect light, and thus heat.
Answer:
I have no clue this qestion is kinda stumping but it a really good question it got me thinking but i don't know if there is a right answer
Explanation:
I don't know
ANSWER:
4 a) Specific elements have more than one oxidation state, demonstrating variable valency.
For example, the following transition metals demonstrate varied valence states:
,
,
, etc.
Normal metals such as
also show variable valencies. Certain non-metals are also found to show more than one valence state 
4 b) Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons.
For example, Carbon-14 is a naturally occurring radioactive isotope of carbon, having six protons and eight neutrons in the nucleus. However, C-14 does not last forever and there will come a time when it loses its extra neutrons and becomes Carbon-12.

EXPLANATION (IF NEEDED):
1. Write out how many atoms of each element is on the left (reactant side) and right (product side) of the arrow.
2. Start multiplying each side accordingly to try to get atoms of the elements on both sides equal.
