Amino Acids- To build proteins.
Hydrochloric Acids- Help humans digest foods.
The answer is 0. If a car goes north 50 mph and turns around and goes 50 mph south the car is back at its starting point therefore the car is back at 0. Hope this helps!
Considering the definition of molarity, the molar concentration is 0.294 .
Molarity reflects the concentration of a solution indicating the number of moles of solute that are dissolved in a given volume.
The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution:
Molarity is expressed in units .
In this case, you know:
- amount of moles of solute= 0.250 moles
- volume= 0.850 L
Replacing in the definition of molarity:
Solving:
molarity= 0.294
Finally, the molar concentration is 0.294 .

Rhodium. FYI google it lol would have been faster
Water is made out of H2O molecules. These molecules are polar. This means that the electrons move closer to the oxygen nucleus (because the oxygen nucleus is heavier).In general , water can dissolve only polar and ionic compounds.So , by taking a look at the substance's structure(using something like X-ray spectroscopy or an electron microscope) , you can determine if it is polar , ionic or nonpolar substance( I won't get in much detail about the types of bonds there are), thus determining if it will disolve in water or not.
