Answer:

Nitrogen (ii) oxide

Explanation:

To know the IUPAC name for NO, we shall determine the oxidation number of N in NO.

NOTE: The oxidation number of oxygen (O) is always – 2.

Thus the oxidation number of N in NO can be obtained as follow:

N + O = 0 (ground state)

N + (– 2) = 0

N – 2 = 0

Collect like terms

N = 0 + 2

N = +2

Thus, the oxidation number of Nitrogen (N) in NO is +2.

Therefore, the IUPAC name for NO is Nitrogen (ii) oxide

What did J. J. Thomson observe when he applied electric voltage to a cathode ray tube in his famous experiment?
Nataly_w [17]

The glass opposite to the negative electrode started to glow. Hence, option B is correct.

<h3>What is a cathode ray tube?</h3>

A cathode-ray tube (CRT) is a specialized vacuum tube in which images are produced when an electron beam strikes a phosphorescent surface.

J.J. Thomson, through his famous Cathode ray experiment, proved that all atoms contain small negatively charged particles known as electrons. In the experiment, he applied electric voltage across a cathode ray tube. a fluorescent material coating was done on the positive side. When the voltage was applied, the positive side has glowing dots.

Hence, option B is correct.

If we react 30 grams of ethane (C2H6 ) with 320 grams of oxygen, how many grams of carbon dioxide would we make
V125BC [204]

The mass of carbon dioxide that would be made by reacting 30 grams C2H6 with 320 grams O2 will be 80 grams

From the balanced equation of the reaction:

2C_2H_6+7O_2---4CO_2+6H_2O

The mole ratio of C2H6 to O2 is 2:7.

  • Mole of 30 grams C2H6 = mass/molar mass

                                        = 30/30

                                       = 1 mole

  • Mole of 320 grams O2 = 320/32

                                       = 10 moles

Thus, C2H6 is the limiting reactant.

Mole ratio of C2H6 to CO2 according to the equation = 1:2

Since the mole of C2H6 is 1, the equivalent mole of CO2 would, therefore, be 2.

Mass of 2 moles CO2 = mole x molar mass

                                    = 2 x 44

                                      = 88 grams

What is the percent composition of nitrogen in N 2 O
mash [69]

Answer:

63.6%

Explanation:

The given compound is:

     N₂O;

The problem here is to find the percent composition of nitrogen in the compound.

First find the molar mass of the compound:

 Molar mass of N₂O = 2(14) + 16  = 44g/mol

So;

 Percentage composition of Nitrogen  = \frac{2 x 14}{44}  x 100  = 63.6%

A spectral line has a wavelength of 7.35 *10-7 m. What is the energy of this radiation?
antoniya [11.8K]

Answer:

2.7 x 10^-19 J

Explanation:

The formula needed for this problem is

E = hν

where E = energy, h = Planck's constant = 6.626x10^-34 and ν is the frequency

c = λν

where c = speed of light = 3x10^8, and λ = wavelength

3x10^8 = 7.35x10^-7 . ν

ν = 4.08 x 10^14 Hz

E = 6.626x10^-34 . 4.08x10^14 = 2.7 x 10^-19 J
