julia-pushkina [17]

A Biochemist is a type of chemist understands the structure of living systems and, in turn, their functions and ways to control them.

<h3>What is the chemistry of living systems called?</h3>

The chemistry of living system is known as Biochemistry.

Biochemistry is a study of the chemical changes that occur in living organisms.

Scientists that study biochemistry are called Biochemists.

Biochemistry studies the structure and function of biological molecules such as carbohydrates, lipids, proteins, e.t.c., as well the chemical reaction they undergo.

Biochemistry also studies the energy changes that occur in living systems.

In conclusion, the chemistry of living systems is called Biochemistry.

What is one advantage of doing a feild experiment instead of a laboratory experiment
Ber [7]

Answer:

  Field experiments can often have the potential to give scientists opportunities that are not possible in a lab setting.

Explanation:

  Having people "act natural" in a lab setting is impossible to truly achieve, as we all know what happens to our mental state and behavior when we are being actively observed. This is also especially helpful when conducting wildlife research, as there are a myriad of different things influencing animal and plant behavior that would be nigh impossible to recreate perfectly in a controlled lab setting.

  Field research can have its disadvantages as well, as it is very hard to only have one thing change (make an independent variable) in a wild environment with ever-changing weather, social effects, etc. Also, you, as the researcher, as causing an impact on the very location that you are observing, which can alter your results in unpredictable ways.

  The thing to remember is that each type of study has its advantages and disadvantages; if they didn't, then we'd all do the same type of research! You have to weigh your research options and figure out which one works best for your situation :)

What’s the ionic equation for lithium + water
disa [49]

Answer:

2Li(s) + 2H₂O(ℓ) ⟶ 2Li⁺(aq) + 2OH⁻(aq) + H₂(g)

Explanation:

An ionic equation uses the symbols (aq) [aqueous] to indicate molecules and ions that are soluble in water, (s) [solid] to indicate insoluble solids, and (ℓ) to indicate substances (usually water) in the liquid state.

In this reaction, solid lithium reacts with liquid water to form soluble lithium hydroxide and gaseous hydrogen .

1. Molecular equation

2Li(s) + 2H₂O(ℓ) ⟶ 2LiOH(aq) + H₂(g)

2. Ionic equation

Lithium hydroxide is a soluble ionic compound, so we write it as hydrated ions.

2Li(s) + 2H₂O(ℓ) ⟶ 2Li⁺(aq) + 2OH⁻(aq) + H₂(g)
