If there is a chemical change, the substance must be different from sodium bicarbonate.
It must have <em>different chemical and physical properties</em>.
I think the correct answer is traits. Please brainiest me! :)
Answer:
While the digestive system collects and removes undigested solids, the excretory system filters compounds from the blood stream and collects them in urine. They are closely connected in controlling the amount of water in your body.
Explanation:
Explanation:
The different subatomic particles in an atom are the:
- Protons which are the positively charged particles.
- Electrons which are the negatively charged particles.
- Neutrons which do not carry any charges.
Protons and neutrons are located in the nucleus of an atom which is the tiny center of the atom.
Electrons orbits around the nucleus and fill the rest of the volume of atom.
Answer:
Dissociation of O-H bond is highly favorable in p-cyanobenzoic acid resulting to higher acidity as compared to m-cyanobenzoic acid.
Explanation:
In p-cyanobenzoic acid, adjacent carbon to carboxyl group (-COOH) gets a partial positive charge due to electron withdrawing resonating effect of carboxyl group as compared to m-cyanobenzoic acid.
Due to this partial positive charge on carbon atom in p-cyanobenzoic acid, O-H bond in -COOH group remains highly polarized towards oxygen atom. Hence, dissociation of O-H bond is highly favorable in p-cyanobenzoic acid resulting to higher acidity as compared to m-cyanobenzoic acid.
Resonance structures are given below.
