Answer:
For part (a): pHsol=2.22
Explanation:
I will show you how to solve part (a), so that you can use this example to solve part (b) on your own.
So, you're dealing with formic acid, HCOOH, a weak acid that does not dissociate completely in aqueous solution. This means that an equilibrium will be established between the unionized and ionized forms of the acid.
You can use an ICE table and the initial concentration ofthe acid to determine the concentrations of the conjugate base and of the hydronium ions tha are produced when the acid ionizes
HCOOH(aq]+H2O(l]⇌ HCOO−(aq] + H3O+(aq]
I 0.20 0 0
C (−x) (+x) (+x)
E (0.20−x) x x
You need to use the acid's pKa to determine its acid dissociation constant, Ka, which is equal to
This is a double replacement reaction; the ions switch twice.
Answer:
The equilibrium will shift left.

In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.
Ivan Pavlov is most known for demonstrating conditioned lreflex in dogs.
<h3>what is conditioned reflex?</h3>
Conditioned reflex is a reflex action which has been conditioned to occur even without the stimulus which produces the reflex.
Ivan Pavlov is known to demonstrate conditioned reflex in dogs.
In his experiment, he trained dogs to salivate at the sound of a bell even if food which is the stimulus that produces salvation was not present.
