Starting at the center, Earth is composed of four distinct layers. They are, from deepest to shallowest, the inner core, the outer core, the mantle and the crust
In a neutral ion, the number of protons would be equal to the number of electrons. You get a positive or negative charge when electrons are lost or gained.
Example: 12/6 C1-
There are 6 protons, 6 neutrons, and 7 electrons.
Answer:
There are 77 millimoles of nitric acid present in 35.0 mL of a 2.20 M solution
Explanation:
Molarity of the solution = 2.20 M
![Molarity=\frac{number\:of\:moles}{Volume\:of\:Solution\:in\:L}\\\\Number\:of\:moles=Molarity\times(Volume\:of\:Solution\:in\:L)\\\\Volume\:of\:Solution=35\:mL=35\times10^{-3}L\\\\Number\:of\:moles=2.20\times35\times10^{-3}=77\times10^{-3}\:moles\:of\:HNO_{3}](https://tex.z-dn.net/?f=Molarity%3D%5Cfrac%7Bnumber%5C%3Aof%5C%3Amoles%7D%7BVolume%5C%3Aof%5C%3ASolution%5C%3Ain%5C%3AL%7D%5C%5C%5C%5CNumber%5C%3Aof%5C%3Amoles%3DMolarity%5Ctimes%28Volume%5C%3Aof%5C%3ASolution%5C%3Ain%5C%3AL%29%5C%5C%5C%5CVolume%5C%3Aof%5C%3ASolution%3D35%5C%3AmL%3D35%5Ctimes10%5E%7B-3%7DL%5C%5C%5C%5CNumber%5C%3Aof%5C%3Amoles%3D2.20%5Ctimes35%5Ctimes10%5E%7B-3%7D%3D77%5Ctimes10%5E%7B-3%7D%5C%3Amoles%5C%3Aof%5C%3AHNO_%7B3%7D)
Therefore, there are 77 millimoles of nitric acid present in 35.0 mL of a 2.20 M solution
Answer: It increases the reaction rate.
