Answer: a) 
: anode
b. 
: cathode
c. 
: anode
Explanation:
Electrochemical cell is a device which converts chemical energy into electrical energy. It consist of two electrodes, anode and cathode.
Oxidation i.e. loss of electrons , which results in an increase in oxidation number occurs over anode.
Reduction i.e. gain of electrons, which results in decrease in oxidation number occurs over cathode.
a. : oxidation : anode
b. : reduction : cathode
c. : oxidation : anode
Following are the types of chemical reactions with a brief overview:
<span>1) Combination (Two elements combine to form a compound)
2) Decomposition (A compound is broken into elements)
3) Single displacement (An element displaces an element present in a compound)
4) Double displacement (The elements of two compounds displace each other)
5) Combustion (Burning Takes places)
<span>6) Redox (Oxidation Reduction Reaction)
If you see the given equation, Al is displacing Ni in the compound NiSO4 and taking its place. Ni is set free as a separate element. So this type of reaction is known as Single Displacement Reaction.</span></span>
Answer:
The pressure inside the chamber is 0.132 atm
Explanation:
Step 1: Data given
The initial volume = 0.027 L
The initial pressure = 1.0 atm
The volume changes to 0.205 L
Step 2: Calculate the pressure
P1*V1 = P2*V2
⇒with P1 = the initial pressure = 1.0 atm
⇒with V1 = the initial volume = 0.027 L
⇒with P2 = the changed pressure = TO BE DETERMINED
⇒with V2 = the changed volume = 0.205 L
1.0 atm *0.027 L = P2*0.205 L
P2 = 0.027/0.205
P2 = 0.132 atm
The pressure inside the chamber is 0.132 atm
I believe it's helium at 0.49 A
- Answer:
Energy release is exothermic reaction whiles energy absorb is endothermic reaction
Explanation:
Exothermic reaction is when the reactant is above the product while endothermic the product is below the reactant in the diagrams we have some part as activation energy
