Answer:
All statements are true
Explanation:
Arrhenius theory:-
The Arrhenius theory was introduced introduced by Swedish scientist named Svante Arrhenius in 1887.
According to the theory, acids are the substances which dissociate in the aqueous medium to produce electrically charged atoms ( may be molecule). Out of these species furnished, one must be a proton or the hydrogen ion, .
Hence, statement 1 is correct.
Bronsted-Lowry base is the specie which accepts the proton form the medium. For example, Benzoate ion is the conjugate base of the benzoic acid. It is a Bronsted-Lowry base and the dissociation of benzoate ion can be shown as:-
Hence, statement 2 is correct.
Acetic acid will dissociate as:-
Hence, statement 3 is also correct.
Answer:
2.1 M is the molarity of the HCl solution.
Explanation:
Molarity of HCl solution =
Volume of HCl solution =
Ionizable hydrogen ions in HCl =
Molarity of NaOH solution =
Volume of NaOH solution =
Ionizable hydroxide ions in NaOH =
(neutralization )
2.1 M is the molarity of the HCl solution.
In a food chain, energy is passed through one link to another. When a herbivore eats only a certain fraction of the energy, (which comes from the food) it becomes new body mass; the rest of the energy is lost as waste or used up by the herbivore in order to carry out its life processes (ex. movement, digestion, reproduction). It doesn’t necessarily threaten the plants survival, there’s also a benefit. When a animals poops out the fruit (defecate) in another area those seeds get carried to new places with the help of a dab of fertilizer and a little bit of moisture. They also help supply nutrients when they die and decompose.
