Why Mendeleev was able to observe periodicity?
mendeleev arranged elements according to atomic mass. He was able to observe periodicity when arranged in this pattern.
What apparatus used to observe reactions?
Berzelius and Erlenmeyer flasks, test tubes, crucibles, cups, etc.
What are Two main kinds of changes that you can observe when chemical reaction occur?
a precipitate is a solid that forms during a chemical reactions
Why is most objects you observe are not elements?
- many elements doesn't exist in pure form in the nature - many objects are made from alloys - many objects are mixture of compounds
What evidence do you have that atoms of certain elements a flame with a specific color?
You do an experiment to gather this evidence and then develop a hypothesis to explain what you observe.
Why Mendeleev was able to observe periodicity?

You can observe burning, corrosion or precipitation.

How can a hypothesis be tested?
observe it ,when there is a quick reaction...compare the reactions in the problem you've been solving..

Why its important to observe an individuals reactions when communicating with them?
Observing an individual's reactions when communicating with them is important because it helps you gauge their understanding, engagement, and emotional state.

What do you use to help you make observations during a scientific experiment?
Use a pen and paper, observe the reactions in the experiement and record it in minor ditails.
