The reaction between ammonia and oxygen is given below:

Chemistry
1 answer:
anyanavicka [17]3 years ago
4 0

Answer:

N2O(g) + 3 H2O(l) ---------------> 2 NH3(g) + 2 O2(g)

Explanation:

If we look at the reaction stated in the question, we will notice that the option chosen in the answer is the reverse of that reaction.

One thing is clear, if a reaction is possible, then its reverse reaction is equally possible. The equilibrium position may shift towards the forward or reverse reaction based on the conditions of the reaction.

Hence if the reaction, 2NH3(g) + 2O2(g) → N2O(g) + 3H2O(l) is possible, then the reaction, N2O(g) + 3 H2O(l) ---------------> 2 NH3(g) + 2 O2(g) is also possible.

Calculate the radius ratio for NaBr if the ionic radii of Na + and Br − are 102 pm and 196 pm , respectively. radius ratio: Base
Fudgin [204]

Answer : The expected coordination number of NaBr is, 6.

Explanation :

Cation-anion radius ratio : It is defined as the ratio of the ionic radius of the cation to the ionic radius of the anion in a cation-anion compound.

This is represented by,

\frac{r_{cation}}{r_{anion}}

When the radius ratio is greater than 0.155, then the compound will be stable.

Now we have to determine the radius ration for NaBr.

Given:

Radius of cation, Na^+ = 102 pm

Radius of cation, Br^- = 196 pm

\frac{r_{cation}}{r_{anion}}=\frac{102}{196}=0.520

As per question, the radius of cation-anion ratio is between 0.414-0.732. So, the coordination number of NaBr will be, 6.

The relation between radius ratio and coordination number are shown below.

Therefore, the expected coordination number of NaBr is, 6.

A child shivers in a cold rain but does not feel cold, what is the biochemistry behind it
algol13

Answer:

Homeostasis is defined as the process by which the internal body system maintains a suitable environment for its proper functions and survival.

When a person temperature drops a signal is sent to the brain which results in a reflex action being observed. The shiver makes the individual warmer and helps in the regulation of the body heat.

Consider the following intermediate chemical equations. 3 equations. 1: upper C upper H subscript 4 (g) right arrow upper C (s)
ladessa [460]

The enthalpy of the reaction is the amount of energy absorbed or lost in the reaction. The enthalpy of the final reaction  is -113.4 kJ.

<h3>What are intermediate reactions?</h3>

The intermediate reactions are the small reactions that takes place in order to achieve the final reaction product.

The given intermediate reactions are:

\rm CH_4\;\rightarrow\;C\;+\;2\;H_2......\Delta H_1=74. 8\;kJ\\CCl_4\;\rightarrow\;C\;+\;2\;Cl_2......\Delta H_2=95. 7\;kJ\\H_2\;+\;Cl_2\;\rightarrow\;2\;HCl......\Delta H_3=-92. 3\;kJ

The final reaction to be achieved is:

\rm CH_4\;+\;4\;Cl_2\;\rightarrow\;CCl_4\;+\;4\;HCl

The second reaction is reversed in order to achieve the final reaction product.

The enthalpy of the final reaction (\Delta H_{rxn}) is given as:

\Delta H_{rxn}=\Delta H_1-\Delta H_2+\Delta H_3

Substituting the values of enthalpy:

\Delta H_{rxn}= 74. 8-95. 7+(-92. 3)\text k\text J\\\Delta H_{rxn}=-113.4\;\rm kJ

The final enthalpy of the reaction is -113.4 kJ. Thus, option B is correct.

Explain the difference between an ignition transformer and a solid-state igniter
bazaltina [42]

Ignition transformer

1.      Weight of the transformer is more.

2.      Voltage output of the transformer is from 10,000 volts to 14,000 volts.

3.      Due to lower voltage output, fuel vaporization and ignition will be slow.

4.      When there is a drop in voltage supply, the transformer gets affected.

5.      Consumption of electricity is more.

 

Solid state igniter.

1.      Igniter weighs very light

2.      Igniter giver voltage output in the range of 14,000 volts to 20,000 volts

3.      Higher voltage output leads to faster vaporization of fuel and ignition

4.      Very small affect is observed when there is a voltage drop.

5.      Less electricity is consumed.
