Answer:
I would say element
Explanation:
because it is made of two different types of atoms chemically bonded together!
I'm sorry if wrong!
Answer:
The value is
Explanation:
From the question we are told that
The equation is
The temperature is
The emf at standard condition is
Generally at the cathode
At the anode
Generally for an electrochemical reaction, at room temperature the Gibbs free energy is mathematically represented as
Here n is the no of electron with value n = 6
F is the Faraday's constant with value 96487 J/V
=>
=>
This Gibbs free energy can also be represented mathematically as
Here R is the cell constant with value 8.314J/K
K is the equilibrium constant
From above
=>
Generally antilog = 2.718
=>
=>
Answer:
A = 2
B = 1
Explanation:
The atomic number of lithium is 3.
Its atomic mass is 7 amu.
It is present in group group 1.
It has one valance electron.
Lithium is alkali metal it form salts.
It is silvery soft metal. It has lowest density as compared to all other metals.
It react vigorously with water.
It is used in rechargeable batteries which are used in camera, mobile, laptops etc.
The electronic configuration of Li:
Li₃ = 1s² 2s¹
Thus,
A = 2
B = 1
Answer:
If a substance undergoes a physical change, then it will retain most of its original properties because no new substance is formed.
If a substance undergoes a chemical change, then it will not retain its original properties because a new substance is formed.
Explanation:
So in shorter words its options 2 and 3
