Acetaldehyde is a substance commonly used in chemical factories. It is often produced by combining ethylene gas and oxygen gas.
Consider the following reaction:
12 molecules of ethylene (CH) react with 6 molecules of oxygen (O2) to produce some
amount of acetaldehyde (C, H,O).
Complete the table below.
Chemical element Number of atoms in the reaction
H
С
o
During this reaction, how many molecules of acetaldehyde (C2H,0) are produced?

idk what is it? is this a question that you know the answer or u dont

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
