Answer:
The first step in forming the ch3cl lewis structure is drawing out all the atoms that exist within the molecule or ion being studied. Then, each atom must have its atomic number written above it. After this, draw lines between every bonded pair of non-identical electrons on adjacent atoms (bonded pairs are called “bonds”).
Look on page 293 of your textbooks to fact check.The symbol for an alpha particle is 4/2 He.The super- script (4) is the mass number (the sum of the numbers of protons and neutrons).The subscript (2) is the atomic number (the number of protons).
Therefore the answer should be: Super-script 4 is the mass number, Subscript 2 is the atomic number

<u>Answer:</u> The molarity of calcium hydroxide in the solution is 0.1 M
<u>Explanation:</u>
To calculate the concentration of base, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is
are the n-factor, molarity and volume of base which is
We are given:
Putting values in above equation, we get:
Hence, the molarity of in the solution is 0.1 M.
