The expectancy of how long a product will last divided by two!
Answer:
0.001 M OH-
Explanation:
[OH-] = 10^-pOH, so
pOH + pH = 14 and 14 - pH = pOH
14 - 11 = 3
[OH⁻] = 10⁻³ ; [OH-] = 0.001 M OH-
Answer:
Answer is given below.
Explanation:
Anode is that electrode where oxidation occurs. Cathode is that electrode where reduction occurs.
In cell representation, half cell present left to salt-bridge notation
is anodic system and another half cell present right to salt-bridge notation
is cathodic system.
So anode is Cu and cathode is Ag.
oxidation: 
[reduction:
]
-----------------------------------------------------------------------------------------------
chemical equation: 
Oxidizing agent is that species which takes electron from another species. Here
takes electron from Cu. Hence
is the oxidizing agent.
Reducing agent is that species which gives electron to another species. Here Cu gives electron to
. Hence Cu is the reducing agent.
When reactants are mixed and heated and liquid collects in the sidearm of the apparatus, a chemical reaction is occurring.
<h3>What is a chemical reaction?</h3>
A chemical reaction is said to occur when reactants are combined to form products. We must note that the formation of products is evidenced by;
- Appearance of a liquid
- Appearance of a gas
- Appearance of a solid
Hence, when reactants are mixed and heated and liquid collects in the sidearm of the apparatus, a chemical reaction is occurring.
