Answer:
the answer should be c
Explanation: why because 37/19 k toward 0+1e +37/18 AR is equivalent to the beta decay and it describes the best beta decay in the formula.
The correct answer to fill the blank in the sentence is A. If a cell is placed in salt water, water leaves the cell by osmosis. It is the spontaneous movement of solvent molecules in a semi-permeable membrane from a higher concentration to lower concentration to achieve equilibrium.
Answer: The hydronium ion concentration of a solution with a pH of 4 is 100 times more than the the hydronium ion concentration of a solution with a pH of 6
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
![pH=-\log [H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH%5E%2B%5D)
1. Solution with pH of 6
![6=-\log [H^+]](https://tex.z-dn.net/?f=6%3D-%5Clog%20%5BH%5E%2B%5D)
![[H^+]=10^{-6}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D10%5E%7B-6%7D)
2. Solution with pH of 4
![4=-\log [H^+]](https://tex.z-dn.net/?f=4%3D-%5Clog%20%5BH%5E%2B%5D)
![[H^+]=10^{-4}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D10%5E%7B-4%7D)
Thus the hydronium ion concentration of a solution with a pH of 4 is 100 times more than the the hydronium ion concentration of a solution with a pH of 6
The amount of 4.86 ml needed to completely react with 11.73 ml of 1.006 m ca(oh)2 is 4.86 ml.
given data to be calculated:-
Ca3(PO4)2 (s) + 6H2O can be used to calculate this: 3Ca(OH)2 (aq) + 2H3PO4 (aq) (l)
ca moles (OH)
2 present 11.00 moles of H3PO4 are required; 7.33 moles of H3PO4 in a volume of ml are required; 7.33/1.508 = 4.86.
<h3>How do moles react to an increase in volume?</h3>
The direction that creates more moles of gas benefits from an increase in volume, and since there are more moles of products in this case, the reaction will shift to the right and produce more moles of products.
