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 .

What is the frequency of green light, which has a wavelength of 4.90 x 10
Lina20 [59]

Answer:

I found:

ν=6×10^14Hz

Explanation:

You can consider that wavelength λ and frequency ν are related through the speed of light in vacuum c as:

c = λ ⋅ ν

so:

3 * 10⁸ = 4.9 * 10-⁷ * V

v =3 *10⁸/ 4.9 *10⁻⁷ = 6 * 10¹⁴HZ

In two or more complete sentences explain how to balance the chemical equation and classify its reaction type.
Andre45 [30]

Answer:

Double displacement reaction

Explanation:

Chemical equation:

H₃PO₄ + NaBr      →    HBr + Na₃PO₄

Balanced chemical equation:

H₃PO₄ + 3NaBr      →    3HBr + Na₃PO₄

Step one:

H₃PO₄ + NaBr      →    HBr + Na₃PO₄

On left side of equation                  On right side pf equation

H = 3                                                   H = 1

P =  1                                                    P = 1

O = 4                                                    O = 4

Na = 1                                                   Na = 3

Br = 1                                                     Br = 1

Step 2:

H₃PO₄ + NaBr      →    3HBr + Na₃PO₄

On left side of equation                  On right side pf equation

H = 3                                                   H = 3

P =  1                                                    P = 1

O = 4                                                    O = 4

Na = 1                                                   Na = 3

Br = 1                                                     Br = 3

Step 3:

H₃PO₄ + 3NaBr      →    3HBr + Na₃PO₄

On left side of equation                  On right side pf equation

H = 3                                                   H = 3

P =  1                                                    P = 1

O = 4                                                    O = 4

Na = 3                                                   Na = 3

Br = 3                                                     Br = 3

Type of chemical reaction:

The given reaction is double displacement reaction on which cation and anion of both reactants are replace with each other.

Complete this brønsted-lowry reaction placing each product by its appropriate label. hso4- + hcn
Yuri [45]

Answer : The balanced reaction is, HSO_4^-+HCN\rightleftharpoons H_2SO_4+CN^-

Explanation :

According to the Brønsted-lowry concept, a substance is known as acid if it can donate a proton and as a base if it can accept a proton.

The given substance may be a molecule of an ion. The reaction of an acid with the base constitutes the transfer of a proton from acid to the base.

The balanced reaction will be,

HSO_4^-+HCN\rightleftharpoons H_2SO_4+CN^-

In this reaction, HCN is an acid and is donating a proton to the base HSO_4^- and both are the reactants. H_2SO_4 is the conjugate acid of HSO_4^- and CN^- is the conjugate base of HCN and H_2SO_4\text{ and }CN^- are the products.

Hence, the balanced reaction is, HSO_4^-+HCN\rightleftharpoons H_2SO_4+CN^-
