Which bicylic compounds are unstable at room temperature?

Chemistry
2 answers:

Answer:

the compounds are:

Chlorine Trifluoride (CLF3)

Substance N (another way to call CLF3)

Azido Azide Azide (C2N14)

Explanation:

The instability of the C2N14 is beyond our handling capabilities. Minor tests of load and friction led to explosive decomposition.

This is the most explosive compound known, ironically two nitrogen atoms linked with a triple covalent bond is the most stable molecule, but in the case of Azido Azide Azide none of its 14 nitrogen atoms is linked by a triple bond, which makes it very unstable.

Substance N in 1930 was a new compound was discovered by Ruff and Krug in Germany. It was too volatile, so it was ignored, until a few years after it sparked interest in Nazi scientists. They named the compound substance n and it showed very particular properties:

· Boils at room temperature and produces toxic gas

· If the gas is ignited it burns at more than 2,400 degrees Celsius

· Explodes on contact with water

· If combined with coal it forms an explosive that detonates on contact with anything else

Seeing these properties and that substance n was so good at setting fire to things that were not flammable like glass or sand the Germans decided to use it.

It is a colorless gas or a highly reactive white solid with a sweet, suffocating odor. It is transported as a greenish-yellow liquid.

It is used in rocket boosters and in the processing of fuels for atomic reactors.

How many moles of copper Il sulfide can be produced from 2.8 moles of sulfur? Cu + S --> CuS​
Kamila [148]

Answer: 2.8 moles of copper (Il) sulfide (CuS) will be produced from 2.8 moles of sulphur.

Explanation:

The balanced chemical reaction is:

Cu+S\rightarrow CuS  

According to stoichiometry :

1 mole of S produce =  1 mole of copper (Il) sulfide (CuS)

Thus 2.8 moles of S will produce=\frac{1}{1}\times 2.8=2.8moles of copper (Il) sulfide (CuS)

Thus 2.8 moles of copper (Il) sulfide (CuS) will be produced from 2.8 moles of sulphur.

The combustion of glucose (c6h12o6) with oxygen gas produces carbon dioxide and water. this process releases 2803 kj per mole of
V125BC [204]

Answer:- 335 kcal of heat energy is produced.

Solution:- The balanced equation for the combustion of glucose in presence of oxygen to give carbon dioxide and water is:

C_6H_1_2O_6+6O_2\rightarrow 6CO_2+6H_2O

From given info, 2803 kJ of heat is released bu the combustion of 1 mol of glucose. We need to calculate the energy produced when 3.00 moles of oxygen react with excess of glucose.

We could solve this using dimensional analysis as:

3.00mol O_2(\frac{1mol glucose}{6mol O_2})(\frac{2803 kJ}{1mol glucose})

= 1401.5 kJ

Now, let's convert kJ to kcal.

We know that, 1kcal = 4.184kJ

So, 1401.5kJ(\frac{1kcal}{4.184kJ})

= 335 kcal

Hence, 335 kcal of heat energy is produced by the use of 3.00 moles of oxygen gas.

A certain man needed 400N of force to pull a load through a distance of 150cm in 8s . Calculatell i) the work done by man ii) th
Igoryamba

Answer:

a) 600 J

b) 75 W

Explanation:

Force= 400 N, distance = 150 cm = 1.5 m, time= 8s

a) Work is the product of force acting on an object and distance (or displacement). The S.I unit of work is the joules.

Work = force × distance = 400 × 1.5 = 600 J

b) Power is the amount of energy transferred per unit time. It is the ratio of work to time. The S.I unit of power is watt

Power = work/time = 600 / 8 = 75 W
