An element R has the atomic number of 12, (i) Draw it electron configuration. (ii) determine the charge of its ion. (iii) write the formula of the compound formed between R and Chlorine. (iv) state the group and period of R in the periodic table.​

they both have a y in them

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

the temperature of the gas, in k, not celsius.
