The landscape region of Long Island is the Atlantic coastal plain.
Answer : The resulting solution will have a pH of 7.
Explanation:
Whenever acid and base reacts with each other to form water molecule is called Neutralization reaction. This water molecules is formed from the hydronium ion (
) from acid and hydroxide ion(
) from base.
When the equal volumes of acid and base of equal strength are combined, the resulting pH of the solution becomes 7.
The pH 7 value means that the solution is neutral.

Answer : The final volume of balloon will be, 3.35 L
Explanation :
Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.
![P\propto \frac{1}{V}](https://tex.z-dn.net/?f=P%5Cpropto%20%5Cfrac%7B1%7D%7BV%7D)
or,
![P_1V_1=P_2V_2](https://tex.z-dn.net/?f=P_1V_1%3DP_2V_2)
where,
= initial pressure = 789 mmHg
= final pressure = 632 mmHg
= initial volume = 2.68 L
= final volume = ?
Now put all the given values in the above equation, we get:
![789mmHg\times 2.68L=632mmHg\times V_2](https://tex.z-dn.net/?f=789mmHg%5Ctimes%202.68L%3D632mmHg%5Ctimes%20V_2)
![V_2=3.35L](https://tex.z-dn.net/?f=V_2%3D3.35L)
Therefore, the final volume of balloon will be, 3.35 L
The question is all about which among the given choices is true or properly describes the valence electron of the metallic bonds. These valence electrons of the metallic bond is shared amongst many atoms so that the metals can be bounded together. Hope this answers your qn. :)
