Consider the titration of 30.0 mL of 0.050 M NH3 with 0.025 M HCl.
Alla [95]

Answer:

60.0mL

Explanation:

For the process of titration , the formula we use is -

M₁V₁ = M₂V₂

Where ,

M₁ = initial concentration

V₁ = initial volume

M₂ = final concentration

V₂ = final volume .

Hence , from the question ,

The given data is ,

M₁ = 0.050 M

V₁ = 30.0mL

M₂ = 0.025 M

V₂ = ?

Now, to determine the unknown quantity , the formula can be applied ,

Hence ,

M₁V₁ = M₂V₂

Putting the respective values ,

0.050 M * 30.0mL = 0.025 M * ?

solving the above equation ,

V₂ = ? = 60.0mL

For the reaction depicted in the molecular scenes, X is red and Y is green.(a) Write a balanced equation.
Vadim26 [7]

The balanced equation based on the scenes is given by ,

X2 + 3Y2 → 2XY3

Given ,

For the reaction depicted in the molecular scenes , X is red and Y is green .

Through observing the scenes , the balanced chemical equation of the scenes is given by ,

The scenes indicates 3 moles of molecule X2 reacts with 9 moles of molecule Y2 to form 6 moles of tetra atomic molecules XY3.

Thus the balanced equation is given by ,

3X2 + 9Y2 → 6XY3

Divide each side of the equation by 3 , we get , the balanced equation as,

X2 + 3Y2 → 2XY3

<h3>What is a balance chemical reaction ?</h3>

A balanced chemical reaction is a type of reaction which include the reactants and products in same amount i.e. the no of mole on both side of the reaction is remains same or balanced .
