That state of matter is known as liquid.
Answer:
AB + CD → AC +BD
Explanation:
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AC +BD
Example:
The following reaction is double replacement reaction.
CaCO₃ + 2HCl → CaCl₂ + H₂CO₃
While,
A + B → AB
Synthesis reaction:
It is synthesis reaction. The reaction in which two or more simple substance react to give one or more complex product.
AB → A + B
Decomposition:
It is the decomposition reaction. The reaction in which one reactant is break down into two or more product.
AB + C → AC + B
Single replacement:
It is the reaction in which one elements replace the other element in compound.
Answer:
(I'm not sure tbh) It's C Polypeptides are formed by 10 or more amino acids
Answer:
Option C. Cu is oxidized at the anode and Ag+ is reduced at the cathode.
Explanation:
The reaction that is taking place in the voltaic cell is:
Cu(s) + 2Ag⁺(aq) → Cu²⁺(aq) + 2Ag(s)
A voltaic cell is an electrochemical cell that uses spontaneous redox reactions, like the above, to generate electricity.
In the rection above, the electrode of the anode is Cu, and the electrode of the cathode is Ag. In the cell, the solution of Ag⁺ produces the oxidation of the Cu(s) which results in Cu²⁺ and Ag(s) (since the Ag⁺ is being reduced). In a voltaic cell, the anode is the electrode at which the oxidation reaction occurs and the cathode is the electrode at which the reduction reaction takes place.
The redox reactions in this system release energy, so a wire connects the two reactions and allows electrons to flow from one side to the other, forming the Voltaic (or Galvanic) Cell.
From all of the above, the correct option is c: Cu is oxidized at the anode, and Ag+ is reduced at the cathode.
