Answer:
Chemistry is used almost everywhere you go. from the car you use to get to work (gasoline burning) to the nuclear reactors that power many homes ( uranium becoming unstable to product electricity.
Its a base
as Na+ dissociates in the water and it has no basic nor acidic properties its neutral]
but the F- that also dissociates has certain basic properties
hope that helps
Answer:
False
Explanation:
It is not true that this is an example of a chemical reaction. This is a typical example of physical reaction.
Most physical changes are often phase changes.
- A phase change is a change in the physical state of a body.
- In this change, it is from solid to liquid.
- Now new substances are formed.
- When substances are changed from one form to another, it is a physical change.
In a chemical change, a new substance is formed at the end of the process.
Explanation:
The steps involved in formation of a sedimentary rock are placed in the correct order as follows.
Step 1: The sediment is deposited by wind, flowing water, or other natural processes.
Step 2: The sediment is gradually buried and compacted.
Step 3: Dissolved minerals completely cement the sediment together.
As a result, it leads to the formation of a sedimentary rock.
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.
