Explanation:
The Gas Law Apparatus is a high-quality demonstrator of the relationship between pressure, volume and temperature of a gas. The pressure gauge shows how pressure affects volume and vice versa. A digital thermometer displays the temperature.
An atom that gains electrons and becomes negatively charged is known as an <u>anion</u><u>.</u>

Answer:
Rb<K<Ga<As<Se<S
Explanation:
We must remember that first ionization energy decreases down the group and increases across the period.
First ionization energy decreases down the group because of the addition of more shells which increases the distance between the nucleus and the outermost electron. Hence, Rb has a lower ionization energy that K.
Across the period, increase in the size of the nuclear charge causes the pull of the nucleus on the outermost electrons to increase thereby increasing the ionization energy. Hence ionization energy increases across the period. For this reason, the ionization energy of Ga<As<Se as shown.
Intermolecular force for solids is high. Whereas low in gases. The smell of agarbatti spreads immediately because the molecules of air diffuses very fastly.
Answer:HCl(aq) + NaOH (aq) -> NaCl (aq) + H2O(l)
Explanation:
The reaction of HCl and NaOH is a neutralization reaction. When an acid and a base react salt and water is produced.
HCl(aq) + NaOH (aq) ----> NaCl (aq) + H2O(l)
Because the reactants and products are ionic compounds, they exist as ions in a solution.
H+(aq) + Cl-(aq) + Na+(aq) + OH-(aq) -------> Na+(aq) + Cl-(aq) + H2O(l)
The aim of a neutralization reaction is the formation of water. Na+(aq) + Cl-(aq) remain the same on both the reactants side and the products side, the net ionic reaction will be
H+(aq) + OH-(aq) -------> H2O(l)
