This is considered a physical change because the water does not change its chemical properties - it is still water. It is simply just moving its shape such as gas form, liquid form, or solid form.
Answer:
in the water, plants and small organisms like plankton take up mercury through passive surface absorption or through food intake. ... Methylmercury biomagnifies through the food chain as predators eat other organisms and absorb the contaminants that their food sources contained.

Answer:
Option 3.
LiOH(aq) + HNO₃(aq) —> LiNO₃(aq) + H₂O(l)
Explanation:
To know which option is correct, we must have an ideal of what is acid–base neutralization.
Neutralization is a reaction involving an acid and a base which produces salt and water only.
With the above information, we can easily detect the equation describing acid-base neutralization reaction by considering the products of each reaction to see the one that has water as part of the products.
From the question given above, only the 3rd equation gas water as part of the products i.e
LiOH(aq) + HNO₃(aq) —> LiNO₃(aq) + H₂O(l)
Hence, equation 3 is an acid-base neutralization reaction
Answer:
false
Explanation:
a physical property can be observed and stay the same but a chemical property can't
