Answer:
The new pH of the solution
Explanation:
Given
pH of bottle of Soda is
As we know that
pH log [H+]
We will derive the hydrogen ion concentration when pH is
log [H+]
Taking anti-log on both the sides, we get -
H+ ion is equal to
When the hydronuim ion concentration reduces by of the original concentration, the new hydrogen ion concentration becomes
The new pH is
Answer: 12 L fluorine gas at STP can be collected from the decomposition of 90.7 g of
Explanation:
The balanced decomposition reaction is shown as
moles of
According to stoichiometry:
2 moles of gives = 3 moles of flourine gas
Thus 0.36 moles of gives =
of flourine gas
Using ideal gas equation :
P = pressure of gas = 1 atm ( at STP)
V = Volume of gas = ?
n = moles of gas = 0.54
R = gas constant = 0.0821 L atm/Kmol
T = temperature = 273 K ( at STP)
Putting the values we get :
Thus 12 L fluorine gas at STP can be collected from the decomposition of 90.7 g of

Explanation:
Monatomic ions:
These ions consist of only one atom. If they have more than one atom then they are poly atomic ions.
Examples of Mono Atomic ions:
Part A:
For P:
Phosphorous (P) has 15 electrons so it require 3 more electrons to stabilize itself.
Charge is
Full ground-state electron configuration of the mono atomic ion:
Part B:
For Mg:
Magnesium (Mg) has 12 electrons so it requires 2 electrons to lose to achieve stable configuration.
Charge is
Full ground-state electron configuration of the mono atomic ion:
Part C:
For Se:
Selenium (Se) has 34 electrons and requires two electrons to be stable.
Charge is
Full ground-state electron configuration of the mono atomic ion:
