b. when a mixture is placed in water, some things will float and others will sink.
c. these can be used to pick out things in a mixture.
d. these tools separate iron materials from other matter.
e. use these to separate certain types of materials, such as harmful matter from water.
match the scenarios with the correct tools.
5.12)____martin is boiling macaroni noodles in a pot of water.
which tool would be useful for separating the noodles from the water?
5.13)____jenny has a mixture of iron nails and silver rings.
which tool would be useful for separating the iron nails from the silver rings?
5.14)____michael wants to remove all the cucumbers from his salad.
which tool would be useful for separating the cucumbers from the salad?
write c for compound or m for mixture to complete the sentences.
5.15)__a__is formed or separated by chemical processes.
5.16)__the materials in a__keep most or all of their properties.
5.17)__a__is formed or separated by physical processes.

Explanation:

• For 5.7: Tongs/fingers can be used to pick out things in a mixture.
• For 5.8: Density is related to whether things float or sink in water.
• For 5.9: Filters are used to separate certain types of materials, such as harmful matter from water.
• For 5.10: Sieves are tools with holes used to separate a mixture by the sizes of its matter.
• For 5.11: Magnets separate iron materials from other matter.
• For 5.12: Sieves (like a colander) can separate noodles (larger) from water (passes through holes).
• For 5.13: Magnets can attract iron nails and separate them from silver rings (non - magnetic).
• For 5.14: Tongs/fingers (represented by option A) can pick out cucumbers from salad.
• For 5.15: Compounds (C) are formed or separated by chemical processes.
• For 5.16: In a mixture (M), materials keep most or all of their properties.
• For 5.17: Mixtures (M) are formed or separated by physical processes.

Answer:

5.12: B (assuming B is a sieve - like tool).
5.13: C (assuming C is a magnet).
5.14: A (assuming A is tongs).
5.15: C
5.16: M
5.17: M
