you must draw a step by step process
pH stands for 'potential of Hydrogen'). A pH value is a number from 1 to 14, with 7 as the middle (neutral) point. Values below 7 indicate acidity which increases as the number decreases, 1 being the most acidic.
Possible answer could be 900 or 450.
Answer:
678 mL.
Explanation:
The balanced reaction between calcium chloride and silver nitrate is shown in figure.
As shown in the equation , each mole of aqueous calcium chloride will rect with two moles of silver nitrate.
The moles of calcium chloride taken = molarity X volume (L)
= 0.37X0.33 = 0.122 mol
the moles of silver nitrate required = 2 X 0.122 = 0.244 mol
the volume of silver chloride required =
M = 0.36 M
mol = 0.244
Putting values
volume = 0.678 L = 678 mL.
Answer : The new pressure acting on a 2.5 L balloon is, 8.6 atm.
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.
or,
where,
= initial pressure = 3.7 atm
= final pressure = ?
= initial volume = 5.8 L
= final volume = 2.5 L
Now put all the given values in the above equation, we get:
Thus, the new pressure acting on a 2.5 L balloon is, 8.6 atm.
