The balanced reaction is 3 Ca ( s ) + N 2 ( g )  →  Ca 3 N 2 ( s ).

<u>Explanation</u>:

A chemical equation is said to be balanced when the total number of atoms present on the reactants side is equal to the total number of atoms present on the product side.

The unbalanced chemical equation is as follows,

                             Ca ( s ) + N 2 ( g )  →  Ca 3 N 2 ( s )

To balance this equation, you need to look at how many atoms of each element are present on each side of the chemical equation.

 Calcium has  1  atom on the reactant and  3  on the products side. To balance the reaction we need to multiply the calcium atom by  3  on the reactants side.

                            3 Ca ( s ) + N 2 ( g )  →  Ca 3 N 2 ( s )    

Now  Nitrogen has a coefficient of  2  on both sides of the reaction. Hence the balanced chemical equation will thus be

                              3 Ca ( s ) + N 2 ( g )  →  Ca 3 N 2 ( s )

(1 point) How many mL of water is added to dilute a 10 mL of 0.4 M solution to a new concentration of 0.1 M?
LiRa [457]

Answer:

The volume of water added is 30 mL

Explanation:

Given data

  • Initial concentration (C₁): 0.4 M
  • Initial volume (V₁): 10 mL
  • Final concentration (C₂): 0.1 M
  • Final volume (V₂): ?

We can find V₂ using the dilution rule.

C₁ × V₁ = C₂ × V₂

0.4 M × 10 mL = 0.1 M × V₂

V₂ = 40 mL

The volume of water added is

V₂ - V₁ = 40 mL - 10 mL = 30 mL

What unit is used to measure cell potential?
Lilit [14]

Volt is the unit to measure cell potential.

Explanation:

The cell potential is the measure of potential difference in the two halves of the electrochemical cell.

It is the measure of how much voltage exists between the two halves of the battery. The unit of volt is joule/coulomb. The cell potential is measured by voltmeter.

The energy per unit charge from the oxidation-reduction reaction to drive the reaction is cell potential.

Three other application of Bernoulli's principle ?
Makovka662 [10]
<h2><u>Answer:</u></h2>

Bernoulli's Theorem in a general sense relates the weight, speed, and rise in a moving fluid (liquid or gas), the compressibility and consistency (internal grinding) of which are insignificant and the flood of which is predictable, or laminar.

(1): We can discover the speed of Efflux of a fluid.

This is given by v= sqrt (2gh), where the fluid is turning out from an opening in a vessel at profundity h from free fluid surface. This condition is known as Torricelli's hypothesis.

(2): Vena Contracta: The fluid stream from gap contracts at a separation minimal outside the opening to a neck, called Vena Contracta.

The territory of cross-segment of a fly is littler than a zone of opening. From this reality, we can discover the coefficient of withdrawal.

(3) : Bernoulli's standard is utilized in the development of Venturimeter, an instrument for estimation of measure of a stream of a fluid through a pipe.

When water is mixed with copper sulfate the water turned a blue colour. Is this a physical or chemical property. Explain your an
Alex17521 [72]

Answer:

Physical

Explanation:

No new properties were added, a blue liquid and a clear liquid making a blue liquid is just a mixture because they have not chemically combined.
