Most transition metal form more than one cation but aluminum forms the Al3+ cation only.
Answer:
3.37 m
Explanation:
<u>Number of moles of solute present in 1 kg of solvent is termed as molality</u>
It is represented by 'm'.
Thus,
Given that:
The mass of LiCl = 15.0 g
Molar mass of LiCl = 42.394 g/mol
The formula for the calculation of moles is shown below:
Thus,
Mass of the solvent = 105 g
Also, 1 g = 0.001 g
So,
Mass of water (solvent) = 0.105 kg
Molality is:
<u>Molality = 3.37 m</u>
Answer: A change in the sequence of DNA bases--> Joining amino acids in sequence --> Appearance of characteristics
Explanation:
A mutation is a permanent shift or change from the normal DNA sequence that makes up a gene and affect traits which makes the sequence becomes different from what is commonly found in people. Mutations vary from distortion of a single DNA building block to a large segment of a chromosome.
When mutation occurs in a cell, for the mutation to affect the traits expressed by the particular cell, it must follow this sequence directly:
A change in the sequence of DNA bases--> Joining amino acids in the sequence --> Appearance of characteristics.
Answer:
When you place an iron nail in a basin of water and leave it for two days, what will happen to the iron nail? It will form rust on the surface of the nail. Rust forms when iron combines with oxygen to form iron oxide.
Explanation:
Assuming they were clean of rust to begin with, and are made of an ordinary steel - they start to rust - will turn orange, and the orange sediment...
Not much if any while it's in the water for that period of time. However once you remove it then it will be exposed two oxygen and will start to ox...
If it is not coated properly It will form Rust .
