what are some exmaples of compunds and mixtures ?

Question

for compounds i have water and salt i need 2 more ?

hetereogenous i found blood and beach sand i need 2 more?

homogenous ? i need 4 please give me some examples . ( something i can probably draw ... )

is coffe hetereo or homo ? and wood ? and ice cream ? what are they ?

Answer 1

compounds: sugar, carbon dioxide, sulfuric acid

Heterogeneous mix: pizza, salad, ice tea,

Homo mixture: milk, koolaid, white vinegar, air, corn oil


coffee: homo mixture
Wood: hetero mixture
ice cream: heter mixture

Answer 2

A compound is chemically bonded, so NaCl is a compound, and as you said H2O, KOH (Potassium hydroxide) is another, and so is Ammonium dichromate (NH4)Cr2O7 is a very unstable compound and quickly decays on heating into simpler substances...steam, nitrogen gas and green chromium oxide.
Mixtures are two things put together without chemical bonding...for example wood chips and sand would be a heterogeneous mixture...they can be separated easily. A mixture of whole grapes and whole cherries would qualify as a heterogeneous mixture...you could manually separate them. In making cement we use sand, lime and aggregate and water and initially it is heterogeneous but changes to become homogenous...the character of being stable and not easily divided or separated. Mixing milk and coffee creates a homogenous liquid. Therefore We have:
1. Compounds, HCl, NaCl, H20, Iron oxide, H2SO4, etc.
2. Heterogenous Mixtures, Blood, sand, wood/sand mixture, iron filings and copper filings
3. Homogenous Mixtures...Milk (most fresh milk is homogenized),coffee/milk, Catsup, air, cough syrup.
