<u>Answer:</u>
a. Oxidising agent: Cl₂
b. Reducing agent: NaBr
c. Oxidised: NaBr
d. Reduced: Cl₂
e. Oxidation numbers before reaction: Cl= 0, Na= +1, Br= -1
f. Oxidation numbers after reaction: Cl= -1, Na= +1, Br= 0
<u>Explanation:</u>
Oxidising agents reduces themselves, oxidising other elements/compounds.
Reducing agents oxidise themselves, reducing other elements/compounds.
Oxidation is the <u>loss</u> of electrons or an <u>increase</u> in oxidation number.
Reduction is the <u>gain</u> of electrons or <u>decrease</u> in oxidation number.
Answer:
3.63m/s²
Explanation:
Given parameters:
Mass of box = 8kg
Net force = 29N
Unknown:
Acceleration of the box = ?
Solution:
To solve this problem, we use Newton's second law of motion which is stated as;
Force = mass x acceleration
Acceleration = =
Acceleration = 3.63m/s²
Answer:
disagree it wont be the same momentum

Answer:
The substrate must fit perfectly with an enzyme's active site this in known as the lock and key fit.
Explanation:
The lock and key model was given by the Emil Fisher. The lock is represent an enzyme which is complementary to its substrate and substrate is called key.
when an enzyme is used to catalyzed the reaction, there are active sites on the enzymes through which substrate bind. The active site have specific geometry which is complementary to the substrate so substrate perfectly fit into it.
It is resemble with the lock and key. As there is a specific key for a specific lock this model is just like this.
