The last one on that list would be your answer
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.
C. Poor conductors of electricity is the correct answer. Metal is shiny Metal is malleable and they lose 1 electron in a chemical reaction.
Given in question ;
volume of ideal gas (v1) = 1.62 L
pressure on ideal gas (p1) = 1atm
volume of sample (v2) = to find
pressure of sample (p2) = 85 atm
As the Temperature is constant. Thus, we apply the Boyle's Law ; P₁V₁ = P₂V₂
To find V₂.
P₁V₁ = P₂V₂
(1 atm)(1.62 L) = (85 atm)(V₂)
V₂ = 1.62/85
V₂ = 0.019 L
Thus the volume of sample in ocean is 0.019 L.
What is Boyle's Law ?
Boyle’s law is a gas law which states that the pressure exerted by a gas (of a given mass, kept at a constant temperature) is inversely proportional to the volume occupied by it. In other words, the pressure and volume of a gas are inversely proportional to each other as long as the temperature and the quantity of gas are kept constant. Boyle’s law was put forward by the Anglo-Irish chemist Robert Boyle in the year 1662.
