false
Explanation:
no because there is 2 hydrogen and 2 oxygen
that would be hydrogen peroxide but water is H2O

Answer:</h3>
All atoms of the same element have the same number of protons
<h3>
Explanation:</h3>
- Atoms are the smallest particles of elements that can take part in a chemical reaction.
- Atoms of an element have the same number of protons but may have a different number of electrons or neutrons.
- Atoms of the same element with different neutrons are called isotopes.
- An element may have two or more isotopes. For example, oxygen isotopes; oxygen-16, oxygen-17 and oxygen-18.
- Atoms may have a different number of electrons when they lose or gain an electron(s) to attain a stable configuration.
Answer:
Carbon dioxide is a gas because the particles surrounding it are more spread out and free from each other. Water is a liquid because the particles are partially spread out and have a medium space to move around. And due to the room temperature, salt's particles can either be hot and move rapidly, or be cold and not move rapidly.
Explanation:
Answers (Based off of my understanding
1.) False, slowing down is decelerating, not accelerating.
2.) True, acceleration is the change in the rate of DISTANCE over time.
3.) True, even though an object is moving, it’s rate of movement is not changing, therefore it is not accelerating.
4.) False, if the plane rose 100mph in 2 hours, 2 / 100 = 50 mph.
5 & 6) Sorry man, can’t see the graphs, if you show them later though I can help you.
D- chemical energy
photosynthesis is the process by which green plants and certain other organisms transform light energy into chemical energy.
