The oxidation numbers for Nitrogen are respectively -3, +5, +4
julia-pushkina [17]3 years ago
3 0

Answer:

The oxidation number are

NH₃: -3

HNO₃ : +5

NO₂ : +4

Explanation:

The oxidation number is calculated considering that

a) oxidation number of hydrogen is +1 in all compounds except hydrides

b) oxidation number of oxygen is -2 in all compound except peroxides, superoxides and compound of fluorine.

a) NH₃ : let the oxidation number of nitrogen is "x"

x + 3 (+1) = 0

Therefore x = -3

b) HNO₃

Let the oxidation number of nitrogen is "x"

+1 + x +3(-2) = 0

x = -5.

c) NO₂

Let oxidation number of nitrogen ix "x"

x + 2(-2)= 0

x = +4

How does cohesion affect the evaporation rate of water
wariber [46]

Answer:

Evaporation occurs because among the molecules near the surface of the liquid there are always some with enough heat energy to overcome the cohesion of their neighbors and escape. At higher temperatures the number of energetic molecules is greater, and evaporation is more rapid.

What are the advantages of using digital signals over analog signals?
Studentka2010 [4]

in digital signals, codes are used while in analogue signals do not use signals.

<h3>What are signals?</h3>

Signals are defined as the instructions which are transferred to another source in other to deliver a message.

There are two types of signals which include the digital and analogue signals.

The digital signals uses codes which is a secret way of sending messages while analogue doesn't use codes.

It is desired to produce 2.25 grams of dichloromethane (CH2Cl2) by the following reaction. If the percent yield of dichlorometha
Allushta [10]

Answer:- 3.12 g carbon tetrachloride are needed.

Solution:- The balanced equation is:

CH_4+CCl_4\rightarrow 2CH_2Cl_2

From given actual yield and percent yield we will calculate the theoretical yield that would be further used to calculate the grams of carbon tetrachloride.

percent yield formula is:

percent yield = (\frac{actual}{theoretical})100

65.5=(\frac{2.25}{theoretical})100

theoretical=(\frac{2.25(100)}{65.5})

theoretical = 3.44 g

From balanced equation, there is 2:1 mol ratio between dichloethane and carbon tetrachloride.

Molar mass of dichloroethane is 84.93 gram per mol and molar mass of carbon tetrachloride is 153.82 gram per mol.

3.44gCH_2Cl_2(\frac{1molCH_2Cl_2}{84.93gCH_2Cl_2})(\frac{1molCCl_4}{2molCH_2Cl_2})(\frac{153.82gCCl_4}{1molCCl_4})

= 3.12gCCl_4

So, 3.12 grams of carbon tetrachloride are needed to be reacted.
