Answer:
Since molarity is defined as moles of solute per liter of solution, we need to find the number of moles of nitric acid, and the volume of solution.
molar mass of nitric acid (HNO3) = 1 + 14 + (3x16) = 15 + 48 = 63 g/mole
1.50 g/ml x 1000 ml = 1500 g/liter
1500 g/liter x 0.90 = 1350 g/liter of pure HNO3 (the 0.9 is to correct for the fact that it is 90% pure)
1350 g/liter x 1 mole/63 g = 21.43 moles/liter = 21 Molar HNO3
= 21 Molar of HNO3
Yes mitochondria does make necrssary chemicals for the cell therefore the answer to your question is yes
Answer:
= -457.9 kJ and reaction is product favored.
Explanation:
The given reaction is associated with 2 moles of 
Standard free energy change of the reaction () is given as:
, where T represents temperature in kelvin scale
So, 
So, for the reaction of 1.57 moles of , 
As, is negative therefore reaction is product favored under standard condition.
Answer:
See below
Explanation:
.045 liter / 22.4 l / mole * 6.022 x 10^23 molecules/mole * 2 atoms/molecule =
( * 2 becuase nitrogen gas is diatomic)
Answer:
A) Cations
Explanation:
a) Cations have a positive charge and are larger than their neutral counterparts!
b) Anions have a negative charge and are smaller than their neutral counterparts
c) Metals can have either a positive or negative charge making it either a cation or an anion
d) Carbon is an element and it can have a charge anywhere from +4 to -4
A good way to remember that cations are positive is to think that CATions are always PAWSitive! ^-^
