Answer:
The answer is Denaturation is reversible
Explanation:
Denaturation of proteins is the process whereby there is a disruption in the tertiary, quaternary or secondary structure of proteins which causes a conformation change in its action
denaturation is reversible, that is, the proteins can regain their native state when the denaturing influence is removed. This process can be called renaturation.
Answer:
The answer is
<h2>4.69 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass of wood = 4.6 g
density = 0.98 g/mL
It's volume is
We have the final answer as
<h3>4.69 mL</h3>
Hope this helps you
Answer:
The law of conservation of mass applies to both cases
When 50 g of sugar undergoes a physical change, say for example melting, the amount of sugar in the solution or melted form will also be 50 grams. This shows that the mass before and after the change was the same, in accordance to the law of conservation of mass. The mass stays the same.
When the magnesium strip is burned, this is a chemical reaction. The problem is that we only measure the mass of one of the substances involved in the reaction which is the magnesium strip, which makes it seem like the mass has increased. Actually, while burning, the magnesium combines with oxygen in the air. This oxygen was present before the reaction, we just did not measure it. And after the reaction it is present in the form of product. But the mass is still conserved.
