Answer:
C a chemical reaction formed
Explanation:
if something changes smell and nothing else it is a chemical reaction, every other answer does not make sense
Answer:
It pushes back with equal force.
Explanation:
This is pretty much newton's first law.
Pb + Mg(NO₃)₂ → Pb(NO₃)₂ + Mg
This reaction would NOT occur because Pb is less reactive than Mg and as such Pb cannot displace the Mg in order for the reaction to occur under normal conditions.
Mg + Fe(NO₃)₂ → Fe + Mg(NO₃)₂
This reaction would occur. This is because Mg is more reactive than Fe and as such can displace it in the reaction, thus allowing the reaction to occur under normal conditions.
Cu + Mg(NO₃)₂ → Cu(NO₃)₂ + Mg
This reaction would NOT occur. Mg is more reactive than Cu, and as such copper cannot displace magnesium in order for the reaction to occur under normal conditions.
Answer:
C) atmosphere → plants → animals → soil
Explanation:
The third choice provides the correct path through which carbon is cycled in nature.
Carbon passes from the atmosphere to plants then to animals and finally to the soil.
- Plants uses carbon dioxide from the atmosphere to manufacture their food.
- The food is made up of giant carbon chains which also provides nourishment for animals.
- When animals digest plant matter, they obtain energy for their process.
- The waste is passed into the soil .
