Chemistry

Rufina [12.5K]2 years ago
3 0

Answer:

Subscripts are small numbers that tell us the number of each type of atom in a compound

If there is no number stated then it automatically means there is one atom present

Coefficients are big numbers in front of formulas that tell us we have more than 1 molecule present

Using the example of 2H₂O

The coefficient (2) multiplies the number of atoms of each element in this formula. For hydrogen 2 × 2 = 4 hydrogen atoms and 2 × 1 = 2 oxygen atoms

Give three examples, from the lab, where potential energy was converted to kinetic energy.
GREYUIT [131]

Give 3 Examples of where potential energy was converted to knlinetic energy:

Curtain

A ball before moving

An apple from the tree then falling down

When the Curtains are still, we call the that potential energy. If you move the curtains around, that is kinetic energy

The ball is still, that is potential energy. Then the ball is moving, the is kinetic energy

There is a apple ganging from a tree, that is potential energy. That apple is fall, this is kinetic energy

Hope this helps

Don't type or write in the answer, I'm not sure what from the lab means. These are a few potential into kinetic energy I could have think of!
