Question

Write down step-by-step method for writing the formula of any five chemical compounds

Answer 1

Answer:

first you want to learn charger of all elements like one example hydrogen charge is 1. and oxygen change is -2 and in some of the problem oxgen change is -1

Explanation:

first two hydrogen bonds with one oxgen and h2o is covalent bond

Answer 2

for this first you have learn to the all chemical

equations and then you have learn about the valency and the nature of the element what is that metal or nonmetal then you make chemical compounds themselves

here are the some chemical compounds given below:

2H+O ------->H20

H2 + so4------> H2so4

Na + cl-------> Nacl

Na + CN-----> NaCN

2Na +2H20-----> 2NaOH +H2gas
