For a given arrangement of ions, the lattice energy increases as ionic radius decreases and as ionic charge increases.
What is ion?
An atom or molecule is said to be an ion if one or more of whose valence electrons have been acquired or lost, providing it a net negative or positive electrical charge.
Faraday knew that metals disintegrated together into solution place at a single electrode and that a second metal was placed first from solution at the opposite electrode, as such matter had to be trying to move underneath the impact of an electrical current even though he was unable to identify the particles trying to move between the electrodes. For a given arrangement of ions, the lattice energy increases as ionic radius decreases and as ionic charge increases.
Therefore, for a given arrangement of ions, the lattice energy increases as ionic radius decreases and as ionic charge increases.

Answer: Wax
Explanation:
Density is defined as the mass contained per unit volume.
Usually solids are more denser than liquid, as molecules in solid are more strongly packed and thus have more mass per unit volume.
Liquids on the other hand contain molecules which are less tightly bound and thus thus contain less mass per unit volume as compared to solid.
Example: Solid wax is more denser than liquid wax.

Answer:
Based on the given reaction, it is evident that the reaction is endothermic as indicated by a positive sign of enthalpy of reaction. Thus, it can be stated that the favoring of the forward reaction will take place by upsurging the temperature of the reaction mixture.
Apart from this, based on Le Chatelier’s principle, any modification in the quantity of any species is performed at equilibrium and the reaction will move in such an orientation so that the effect of the change gets minimized. Therefore, a slight enhancement in the concentration of the reactant will accelerate the reaction in the forward direction and hence more formation of the product takes place.

Answer:A medication break can ease side effects. A lack of appetite, weight loss, sleep troubles, headaches, and stomach pain are common side effects of ADHD medication.
Explanation: It may boost your child’s growth. Some ADHD medications can slow a child’s growth in height, especially during the first 2 years of taking it. While height delays are temporary and kids typically catch up later, going off medication may lead to fewer growth delays.
It won’t hurt your child. Taking a child off ADHD medication may cause their ADHD symptoms to reappear. But it won’t make them sick or cause other side effects.
