Atoms and Molecules Quiz
Test your knowledge on the fundamental concepts of atoms and molecules with this engaging quiz! Discover how well you understand key principles such as the law of conservation of mass, Dalton's atomic theory, and chemical compounds.
Whether you're a student, teacher, or science enthusiast, this quiz will challenge you with questions like:
- How much ammonia is formed from hydrogen and nitrogen?
- What did Ayush observe after burning wood?
- What is the mass of oxygen in water?
When 3 g of hydrogen combines with 14 g of nitrogen it gives off 17 g of Ammonia, how much ammonia will be formed when 3 g of Hydrogen will combine with 28 g of nitrogen ?
34 g
17 g
20 g
40 g
Ayush wanted to verify the law of conservation of mass, he burnt a piece of wood weighing 250 g in air and then he measured the mass of ashes. What will he observe ?
Mass of ashes = 250 g
Mass of ashes > 250g
Mass of ashes < 250 g
Information insufficient
Aadi thought that Why only Ayush ! So he also performed one experiment to verify the law of definite proportion, he took two samles of water one from tap water and another one from R.O. He Found the ratio of oxygen and hydrogen within the molecules of hydrogen, what will he find
Both sampes are haiving H:O = 1:8
Tap water has H:O = 1:8
R. O. Water has H:O = 1:16
