NaOH is an example of an ionic crystal.
Option a
<h3><u>Explanation:</u></h3>
Sodium Hydroxide is a "white solid ionic compound" consisting of sodium cations Na+ and hydroxide anions 
. If we look at the crystal structure of NaOH, we can see that it has the combinations of ionic and covalent bonds. The bond that is shared between Oxygen ( O ) and Hydrogen ( H ) is the covalent bond.
The Sodium ( Na ) is bonded with an "ionic bond to the hydroxide part of the compound". NaOH is an ionic solid because it is formed by the combinations of metal and non-metal. When the crystal of NaOH is dissolved in water it dissociates into Na+ ions (which is ionic in nature) and ions which bonds ionically to the other compounds.
Option D
The car is accelerating, because if it were at rest you wouldn't see the line, and if the car was going at constant speed (forwards or backwards) then the line would be straight.

Answer:
The density of the liquid in beaker B is less than the that of ice.
Explanation:
Ice will float if its mass is less than the mass of the liquid it displaces.
For example, the density of ice is less than that of water.
A 10 cm³ cube of ice has a mass of about 9 g, while the mass of 10 cm³ of water is 10 g. Thus, 9 g of ice displaces 10 g of water.
The denser water displaces the lighter ice and the ice floats to the top.
If the density of the liquid is <em>less than</em> that of water, say, 8 g/cm³, the ice will displace only 8 g of the liquid. The ice will sink.
