<h3>Additional information :- </h3>

  • It is harmful rays as a continuous effect on humans can cause skin and eye disorders. ... A large amount of UV rays comes from the sun is absorbed by the ozone layer in the atmosphere. Some other sources of UV rays are black lights, mercury lamps, and tanning lights.

Uses of UV Rays

  • The UV light is found in nature from sunlight and the application of sunlight is present in every field. It is present in both commercial and industrial purposes. Generally, it is used in purifying air, water treatment, skin treatment, indoor gardening, things identifying, and more uses by UV lamps.

  • The UV rays are used in a wide range, ranging from medical therapy to photography.

Gaseous ammonia chemically reacts with oxygen o2 gas to produce nitrogen monoxide gas and water vapor. Calculate the moles of ni
Sergio [31]

Answer: 0.050 moles of nitrogen monoxide are produced by 0.050 moles of ammonia.

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced chemical reaction is:

4NH_3(g)+5O_2(g)\rightarrow 4NO(g)+5H_2O(g)

According to stoichiometry:

4 moles of ammonia produce = 4 moles of nitrogen monoxide

Thus 0.050 moles of ammonia produce =\frac{4}{4}\times 0.050=0.050 moles of nitrogen monoxide

A sample of pure NO2 is heated to 338 ∘C at which temperature it partially dissociates according to the equation 2NO2(g)⇌2NO(g)+
natima [27]

Answer:

A sample of pure NO2 is heated to 338 ∘C at which temperature it partially dissociates according to the equation 2NO2(g)⇌2NO(g)+O2(g) At equilibrium the density of the gas mixture is 0.515 g/L at 0.745 atm .

(4x^2)x

Kc= -----------

(A-2x)^2

PV=nRT

n/v = P/RT = .745/(0.0821)(334+273) = .01495

To Find the initial molarity of NO2

(mol/L)(g/mol) + (mol/L)(g/mol) + (mol/L)(g/mol)= g/L

Thus:

46(A-2x) + 2x(30) + 32x = .515 g/L

46A-92x+60x+32x = .515

46A=.515

A=.01120 M

Using the total molarity found

(A-2x)+2x+x = .01495 M

A+x=.01495

Plug in A found into the above equation:

.01120+x = .01495

x=.00375

Now Plug A and x into the original Equilibrium Constant Expression:

(4x^2)x

Kc= -----------

(A-2x)^2

Kc = 0.000014

Balance the equations.<br> Zn+ HCl →<br> ZnCl2 +
motikmotik

Answer:

Zn + 2HCl → ZnCl2 + H2

Explanation:

Zn + HCl → ZnCl2 +

The complete equation is given below:

Zn+ HCl → ZnCl2 + H2

Now we can balance the equation by doing the following:

There are 2 atoms of Cl and 2 atoms of H on the left. This can be balanced by putting 2 in front of HCl as shown below:

Zn + 2HCl → ZnCl2 + H2
