<span>In the reverse reaction HF is a reactant.</span>
Buffer solution is made up of weak acid or base with its conjugate salt. It resists the change in pH of the solution. When acid or base is added to the buffer solution, the pH gets stabilized but the direction of reaction is opposite. Thus, the reaction is same but the one moves backward and other moves in forward direction.
A buffer solution can be defined as:
HA +NaA
Here, NaA is in dissociated form as follows:
NaA\rightarrow Na^{+}+A^{-}
when acid is added it reacts with A^{-} to form HA and reaction moves in backward direction. When base is added it reacts with HA to form more A^{-} and reaction moves in forward direction.
If acid is added
Answer:
The group 15 elements: the pnicogens
Explanation:
The group 15 elements, nitrogen, phosphorus, arsenic, antimony and bismuth, all have the general valence shell electronic configuration ns2np3. They can all exist in the +3 or +5 oxidation state, with the +3 state increasing in stability as we move vertically down the group.
Answer:
<h2>10 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
m is the mass
f is the force
From the question
mass = 3.5 kg
force = 35 N
We have
We have the final answer as
<h3>10 m/s²</h3>
