Living: biotic
Non-loving: abiotic
Answer:
c. a small amount
Explanation:
Trace elements (or trace metals) are minerals present in living tissues in small amounts.
Explanation:
three things that you would notice a chemical reaction is the change of color and change in odor and the change in temperature
HF + NaOH = NaF + H2O
Aqueous sodium fluoride (NaF) and water are the products of the reaction between hydrofluoric acid (HF), a weak acid and sodium hydroxide (NaOH), a strong base.
It is a straightforward acid-base reaction, despite the fact that hydrogen fluoride is a weak acid that doesn't completely dissociate in water (the equilibrium between the dissociated & undissociated acid will however be pushed to the right as the reaction progresses and all of the acid will eventually be neutralized). Water and sodium fluoride are the products
What exactly is an acid-base reaction?
An acid-base reaction is a chemical reaction that occurs between the reactants, which are an acid and a base. This reaction produces salt and water as byproducts. An acid-base reaction is a double replacement reaction in which ions swap positions.

The pressure inside the flask on heating it is given as 1.21 atm.
<u>Explanation:</u>
As per Guy Lussac's law, the pressure of any concealed volume of gas particles will be directly proportional to the temperature of the container of the gas particles.
So P ∝ T
To convert celsius to kelvin, add 273.15 to the temperature value in celsius
Since, here the initial temperature of the flask is given as 24°C, so in kelvin it will be 297.15 K. Similarly, the final temperature is said to be 104°C which will be equal to 377.15 K. Then the final pressure will be increased as there is increase in temperature. So, the final pressure inside the flask can be obtained as
So, the pressure inside the flask on heating it is given as 1.21 atm.
