Answer:
Human body systems can be compared to anything that has many parts doing specialized jobs to help the whole. Here's an example: The human body is like a city. The nervous system of the body is like the government of the city because the nervous system controls the body like the government controls the city.
Molecules in the gaseous state have the highest kinetic energy. This is because they are free to move around in random directions.
Freezing point. because toxicity is a chemical property as well as pH and flammability is dependent on the items chemical composition <span />
The metal that will react is Cobalt.
The equation for the reaction is,
Co + Ni(NO3)2 → Co(NO3)2 + Ni
The above reaction is an example of Displacement Reaction. Displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound.
Cobalt is more reactive than Nickle in the reactivity series so it displaces Nickle from Nickle Nitrate and forms Cobalt Nitrate.
Reactivity series is a list of metals arranged in decreasing order of their reactivity. The metals with the greatest reactivity are at the top, followed by those with the lowest reactivity. Higher-ranking metals in a series can force lower-ranking metals out of their salt solution for any two metals in the series.
