Covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron. Linear, tetrahedral and trigonal planar geometries would produce a nonpolar molecule.
Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.
Using VSEPR and electron pair repulsion, we can easily find that linear, tetrahedral and trigonal planar geometries would produce a nonpolar molecule if we assume that all of the atoms attached to the central atom were identical. Any geometries which have center of symmetry will produce non polar molecule.
Therefore, linear, tetrahedral and trigonal planar geometries would produce a nonpolar molecule.

According to Charle's law, the new volume of the balloon will be 600 cm³ if pressure is kept constant.
Charles law is an experimental gas law which provides description about the behavior of gases which tend to expand on heating.It states that, at constant pressure, the temperature is in direct proportion with the volume that is,V∝T or V₁/T₁=V₂/T₂.The relation between volume and temperature is linear as the temperature increases volume also increases.
The graph of volume versus temperature is a straight line passing through the origin.The law was proposed by Jacques Charles in relation to ideal gases.
Substitution of the given values in the given formula, V₂= 200×180/60= 600 cm³.
Thus, the new volume of the balloon will be 600 cm³ if pressure is kept constant.

Let x represent the new volume:
cross multiply:
then simplify to get 600cm^3
Hope this helps :)

B. Ionic solids have higher melting points than molecular solids.
A candle placed between two plane mirrors inclined at an angle of 45 degrees will form 7 images. This is due to multiple reflections between the mirrors. The number of images depends on the angle between the mirrors.
In physics, when a candle is placed between two plane mirrors inclined at an angle of 45 degrees, 7 images will be formed. This happens due to multiple reflections between the mirrors. As per the formula for number of images n = 360/θ - 1, where θ is the angle between the mirrors, for an angle of 45 degrees, we get n = 360/45 - 1 = 7. The actual number of images can be less than this if they overlap each other.
