In the container with a volume of 1 L, the total amount of gas is 0.0446 moles, whereas in a 3 L container, it is 0.1334 moles. Explanation: Since 1 mole of gas occupies 22.4 liters, to find the total gas quantity present in both the 1 L and 3 L containers, we divide the respective volumes by the reciprocal of 22.4 liters, leading to the determination of the moles of gas at each volume. Hence for 1 L, there are 0.0446 moles, and for 3 L, it is calculated to be 0.1334 moles. Thus, it can concluded that the number of moles increases with a rise in volume or expansion of gas.
Answer:
Al (s) + AgClO3 (aq) will undergo a chemical reaction.
Al(s) + 3AgClO₃(aq) -----> Al(ClO₃)₃(aq) + 3Ag(s)
Cd(s) + CuNO3(aq) will also engage in a chemical reaction.
Cd(s) + 2CuNO₃ -----> Cd(NO₃)₂ + 2Cu
Explanation:
In chemical reactions, metal elements positioned lower in the activity series typically cannot replace those positioned higher in the series.
Metals located lower on the activity series are less likely to oxidize.
The activity series is referenced in this solution. (Note: While Cadmium is not directly illustrated, it falls between Iron (Fe) and Cobalt (Co) within the series.)
- Lead is significantly lower than Magnesium in the activity series, so it cannot displace Mg2+ ions in a solution.
- Aluminium ranks higher than Silver in the series; thus, it can easily oxidize and replace Silver ions from its solution.
- Cadmium is capable of displacing Copper in solution since it ranks higher than Copper in the activity series.
- Platinum is unable to displace Cobalt from a solution, as it ranks lower than Cobalt in the activity series.
<span>The question asks, 'which statement most accurately describes the formation of an ionic bond. The correct selection is A. Ionic bonds are established through the total transfer of electrovalent electrons from one atom to another. The atom that gives up the electron becomes a positively charged ion, whereas the atom that acquires the electron becomes a negatively charged ion.</span>
A dipole consists of a pair of equal but opposite charges. Since similar charges repel each other while opposite charges attract, when dipoles are placed in an electric field, the positive end is drawn toward the negative end of the field and vice versa. This behavior leads to movement or a stable position depending on how the field is aligned. If we consider the interaction with other dipoles, this influence might be hindered.
