Question

Constants | Periodic Table Part A Write a chemical formula for each molecular model. (Blue ball represents nitrogen atom, red ball represents oxygen atom, white ball represents hydrogen atom, black ball represents carbon atom, yellow ball represents sulphur atom.) Express your answer as a chemical form Submi Request Answer Part B Express your answer as a chemic Submi Request Answer Part C

Answer 1

PART A : here white balls = 3

blue balls =1

given ; white ball represents hydrogen and blue ball represents nitrogen

so formula of compound will be NH₃

Part B : here white balls = 10

black ball =4

Given; white ball represent hydrogen and black ball represents carbon atom

so compounds chemical formula will be C₄H₁₀

Part C: here red balls =3

yellow ball = 1

Given : red ball represents oxygen atom and yellow ball represents sulphur atom

so compound chemical formula will be SO₃
