Answer:
Bile
Explanation:
Bile is secreted by the liver to help in the breaking down of food particles.
Answer:
The answer is: Hydrolysis
Explanation:
Hydrolysis is the chemical method in which water molecule is added to a molecule, which leads to the cleavage of one or more chemical bonds in the molecule. In this reaction, the water molecule acts as a nucleophile and breaks down the large molecules like polymers into smaller molecules such as monomers. Hydrolysis reaction includes fragmentation, elimination substitution reactions.
Answer:
The frequency of photon is 0.75×10¹⁵ s⁻¹.
Explanation:
Given data:
Energy of photon = 5×10⁻¹⁹ J
Frequency of photon = ?
Solution:
Formula;
E = hf
h = planck's constant = 6.63×10⁻³⁴ Js
5×10⁻¹⁹ J = 6.63×10⁻³⁴ Js ×f
f = 5×10⁻¹⁹ J / 6.63×10⁻³⁴ Js
f = 0.75×10¹⁵ s⁻¹
The frequency of photon is 0.75×10¹⁵ s⁻¹.

<u>Answer</u>: Solid Cu
Since this is a <u>voltaic cell</u>:
<u>Copper</u> is the cathode, therefore having a positive charge.
<u>Zinc</u> is the anode, therefore having a negative charge.
(Also, I took the exam and it's correct; good luck everyone!)
