Answer:
The answer is explained below
Explanation:
a) The Breaking down/ electrolysis of water produces oxygen gas and hydrogen gas. The word equation is given by:
Water ⇒ Hydrogen + Oxygen
b) The synthesis of water is the combination of two molecules of hydrogen and one molecule of oxygen to produce two molecule of water. The word equation is given by:
Hydrogen + Oxygen ⇒ Dihydrogen monoxide
c) Sugar decomposes to produce carbon and water. The word equation is given by:
Sugar ⇒ Carbon + Water
d) Photosynthesis is the process in which energy from sunlight is used by plant for growth
The reaction of photosynthesis in word form is given by:
Carbon dioxide + Water ⇒ Glucose + Oxygen
Explanation:
number of mole s of H
2
= 0.25 moles
number of molecules = moles * Avogadro’s Number
number of molecules = 0.25×(6.022×10
23
)
number of molecules = 1.505×10
23
single molecule of hydrogen contains two H-atoms. So,
number of atoms = 2×(1.505×10
23
) = 3.01×10

Answer:
the lithosphere is broken into sections called plates.
Answer:
The answer to your question is because of the force of friction between the ball and the ground.
Explanation:
Exactly, Newton's first law states that every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change that state by forces impress on it.
After analyzing Martin's experiment we could conclude that Newton's first law of motion is wrong but we must remember that between a body and the surface there is a force of friction that causes that the object comes to stop.
We can not see this force but it is there.
