Answer:
A major characteristic of mixtures is that the materials do not chemically combine
Explanation:
Mixtures can be divided into those that are evenly distributed (homogeneous) and those that aren't (heterogeneous)
Explanation:
- Chemical .
- As you can't get sodium or chloride back from sodium chloride.
- Sodium chloride is a ionic compound so the bonding is too hard to break .
There are two types of reactions
- Physical
- Chemical
The labeled diagram is given in the image attached.
As it can be seen from the image that freezing is when energy is removed from the system at 0 ⁰ while melting is when energy is added at 0⁰.
Also when energy is added at 100⁰C, it causes boiling while when it is removed at 100⁰C, it causes condensation.
Melting point of water is 0⁰C while boiling point is 100⁰C
M2= 0.35M
Formula: M1 • V1 = M2 • V2
1) 25.0mL • .500M = 35.5mL • (x)
2) 12.5 = 35.5 • (x)
3) 12.5/35.5 = x
4) 0.35211 = x = M2
Hope this helps!
