The water molecule<span> has two </span>hydrogen<span> atoms joined to one </span>oxygen<span> atom by single covalent bonds. </span>Because oxygen is more electronegative than hydrogen<span>, the electrons of the covalent bond spend </span>more <span>time closer to the </span>oxygen<span> then </span>hydrogen<span> which creates a polar covalent bond. Hope this answers your question. Have a great day!</span>
Explanation:
A process in which water vapor changes into liquid state is known as condensation. As we know that when energy is released in a reaction then it is known as exothermic reaction and when energy is absorbed in a reaction then it is known as endothermic reaction.
As vapors have high energy so, when they change into liquid state then heat energy is released by them. Therefore, condensation is an exothermic reaction.
As per Le Chatelier's principle, any disturbance caused in an equilibrium reaction will tend to shift the equilibrium in a direction away from the disturbance.
So, when there will occur a decrease in temperature then molecules of a gas will come closer to each other. Hence, there will also occur a decrease in vapor pressure of the gas.
Answer: B) Wood Shavings
Reason/Explanation:
Notice what options A, C, and D have on common. Ice, salt and sugar. Those are all dissolvable. Insoluble means un-able to dissolve. It can't dissolve. Wood shavings can't dissolve in water. They will just float. Sugar, salt and ice will all dissolve. Wood shavings won't.
