If 45.0 mL of a 0.0500 M HNO3, 10.0 mL of a 0.0500 M KSCN, and 30.0 mL of a 0.0500 M Fe(NO3)3 are combined, what is the initial
jeka94

Answer:

the  initial concentration of SCN- in the mixture is 0.00588 M

Explanation:

The computation of the initial concentration of the SCN^- in the mixture is as follows:

As we know that

KSCN \rightarrow K^ + SCN^-

As it is mentioned in the question that KSCN is present 10 mL of 0.05 M

So, the total milimoles of SCN^- is

= 10 × 0.05

= 0.5  m moles

The total volume in mixture is

= 45 + 10 + 30

= 85 mL

Now the initial concentration of the SCN^- is

= 0.5 ÷ 85

= 0.00588 M

hence, the  initial concentration of SCN- in the mixture is 0.00588 M

What is the effect on the equilibrium when sodium formate is added to a solution of formic acid? hcooh( aq) + h ( aq) right arro
artcher [175]

There is no effect on the equilibrium when sodium formate is added to a solution of formic acid for hcooh( aq) + h ( aq) right arrow choo –( aq).

Equilibrium is characterized as a state of equilibrium or a stable situation in which conflicting forces balance one another out and no changes are taking place. In terms of economics, equilibrium occurs when supply and demand are equal. When you are composed and steady, you are in an equilibrium state.

An object is considered to be in an equilibrium condition when all of the forces acting on it are in balance. If the upward forces are equal to the descending forces and the rightward forces are equal to the leftward forces, then the forces are said to be balanced. Several instances of equilibrium include a book that is open and at rest. a vehicle that is going steadily.

Answer:

Chemical weathering

Explanation:

This is a chemical weathering since chemical change is involved. water flows through the rock, it dissolve the rock particles, reacting with the minerals salts in the rock there by producing new substances, ultimately leading to wearing off of the rock particles
