STALIN [3.7K]3 years ago
5 0

Answer:

a) nitrogen

b) nitrogen =5

Oxygen = 6

Fluorine =7

Explanation:

Usually, if we have two or more elements in a compound, the central atom in the compound is the atom having the least value of electro negativity.

If we consider fluorine, oxygen and nitrogen; nitrogen is the least electronegative of the trio hence it should be the central atom of the triatomic molecule.

The number of valence electrons on the valence shell of each atom is shown below;

nitrogen =5

Oxygen = 6

Fluorine =7

What is the name of this hydrocarbon?
jenyasd209 [6]

Answer:

2-methylebutane

Explanation:

it is a hydrocarbon and there is a specific Rule for its nomenclature.

that is known as IUPAC naming system. According to it

  • The compound that has all single bonds name ends on ane.
  • Names according to the number of Carbons,

                * For one carbon compound it is known as methane,

                * For 2 ethane,

                * For 3 propane

                * For 4 Butane and so on.

  • select the longest chain of compound
  • Start numbering with lowest substituted position at carbon
  • branch compound name as Iso and neo as whole

So keeping in mind the compound can be named as

2-methylebutane

  • As the longest chain contain four carbon atoms so it will name as butane
  • The substitution of methyl group is on C-2

*Note: it can also named as isopantane as it is branched and have five carbons but it could not be 3-isopentane.

If the order of a reaction with the regard to reagent A is 2, when the concentration of A doubles, the rate will
Anarel [89]

Answer:

Rate will double

Explanation:

Since the concentration of A is doubling the rate of reaction will also double, since in this scenario concentration is proportional to rate of reaction. So if the concentration of A were to triple the rate of reaction would also triple.

if the lightbulb receives 100 J of electrical energy, and gives off 75 energy, how much heat (thermal energy away from the light
oksano4ka [1.4K]

Answer:

Amount of heat energy released by light bulb = 25 joules

Explanation:

Given:

Energy receive by light bulb = 100 Joules

Energy released by light bulb as light energy = 75 Joules

Find:

Amount of heat energy released by light bulb

Computation:

We know that, energy is neither be created nor destroys

So,

Using Law of conservation of energy

Energy receive by light bulb = Energy released by light bulb as light energy + Amount of heat energy released by light bulb

100 = 75 + Amount of heat energy released by light bulb

Amount of heat energy released by light bulb = 100 - 75

Amount of heat energy released by light bulb = 25 joules
