Water can act as either a base or an acid. Water acts as an acid by donating a hydrogen ion when it reacts with a stronger base such as sodium hydroxide. Water may also act as a base when it accepts hydrogen ion when reacting with a strong acid such as hydrochloric acid. This is based on Bronsted concept and definition of a base ( proton acceptor) and acid (proton donor). Such a compound that can act as a base and as an acid is called an amphiprotic molecule.
Answer:
D.4
Explanation:
It contains a carbon atom that bonds to six other atoms instead of the four we have been told carbon is limited to. Atoms form molecules by sharing electrons. Carbon has four electrons that it can share with other atoms
Autotrophic.
Dark reaction happens in the photosynthetic process of plants or autotrophs.
(a) A giant redwood tree = Autotroph
(b) A spider = Heterotroph
(c) A rose bush = Autotroph
(d) A mushroom = Heterotroph
(e) A blue whale = Heterotroph
<span>Autrophs are the organisms that have the capacity to form their own food from inorganic substances like the carbon dioxide. </span>
<span>Heterotrophs are the organisms that cannot produce their own food but depends on other animals or plants for their nutritional needs.</span>
