The model of photosynthesis used by biologists begins when chlorophyll splits a water molecule into hydrogen and oxygen. The oxygen from the water is a waste product that is released as a gas. In later stages of photosynthesis, carbon dioxide from the air and hydrogen from the water unite to form glucose. Photosynthesis usually takes place in the leaves of green plants. The food produced is a simple sugar called glucose. Some of the food made during photosynthesis is used by plants for their growth and development. The rest is stored in the plant.
Answer:
Yes.
Explanation:
Wasting household water does not ultimately remove that water from the global water cycle, but it does remove it from the portion of the water cycle that is readily accessible and usable by humans. Also, "wasting" water wastes the energy and resources that were used to process and deliver the water.
Answer:
CHOOH (aq) + H₂O (l) ⇄ HCOO⁻ (aq) + H₃O⁺ (aq)
Weak acid Base Conj. strong base Conj. acid
H₂S (aq) + NH₃ (aq) ⇄ NH₄⁺(aq) + HS⁻ (aq)
Weak acid Weak Base Conj. strong acid Conj. strong base
Explanation:
To determine the acid-base pairs in the example below we follow the Brownsted Lowry theory.
An acid releases protons
A base accepts protons
CHOOH (aq) + H₂O (l) ↔ HCOO⁻ (aq) + H₃O⁺ (aq)
Formic reacts to water in order to produce formate and hydroniums
Formic release a proton → Acid
Formate can accepted the proton → Conjugate base
Water will be the base, because it will acepted the proton, so the hydronium will be the conjugate acid, because it will release the proton to become water again.
H₂S (aq) + NH₃ (aq) ⇄ NH₄⁺(aq) + HS⁻ (aq)
The sulfidric behaves as an acid, it release the proton to ammonia.
The acid sulfide, becomes the base. It can accept the proton for being, H₂S again.
Then the ammonia is the base (it can accept H⁺) and the ammonium is the conjugate acid (it release the H⁺)
The kinetic energy of an object depends on two factors: mass(m) and velocity(v). The mass of an object can be measured in kilograms(kg) and velocity of the object in meters per second(m/s).
