Answer:
NH₄Cl (aq) + NaOH (aq) -> NaCl (aq) + H₂O (l) + NH₃ (g)
(NH₄)₂CO₃ (aq) + 2KOH (aq) -> K₂CO₃ (aq) + 2H₂O (l) + 2NH₃(g)
NH₄NO₃ (aq) + LiOH (aq) -> LiNO₃ (aq) + H₂O (l) + NH₃ (g)
Explanation:
The gas liberated when an alkali reacts with an ammonium salt is NH₃ (ammonia), not CO₂.
Answer:
A chemical bond formed when two atoms share two pairs of electrons is a<em> </em><em>d</em><em>o</em><em>u</em><em>b</em><em>l</em><em>e</em><em> </em>bond; it is best described as a <em>c</em><em>o</em><em>v</em><em>a</em><em>l</em><em>e</em><em>n</em><em>t</em><em> </em><em>b</em><em>o</em><em>n</em><em>d</em><em>.</em>
Explanation:
A chemical bond in which two pairs of electrons are shared has to be defined as covalent since ionic bonds don't involve electron sharing. They consist only of electrostatic attraction between ions.
weight depends on the force of gravity that is exerted on it.
I think the correct answer is the second option. The criteria that are responsible for deciding whether a heterogeneous mixture is a colloid or a suspension would be <span>whether the particles remain suspended for an extended period of time</span>
