Why dihydrogen is not very reactive under normal conditions?​

Chemistry
1 answer:
drek231 [11]3 years ago
3 0
It is inert.ie. not reactive as H-H bond has high dissociation enthalpy . Two atoms of hydrogen combine to form molecular hydrogen by a covalent bond. Hence , molecular hydrogen is more stable than atomic hydrogen and does not react under normal conditions.

An object with a mass of 4.0 kg has a force of 12.0 newtons applied to it. What is the resultant acceleration of the object?
Zigmanuir [339]

Answer:

3m/s²

Explanation:

Force applied to an object can be calculated thus;

F = ma

Where;

F = force applied (Newtons)

m = mass of substance (kg)

a = acceleration (m/s²)

According to the information provided in this question, F = 12.0 newtons, m = 4.0 kg, a = ?

Derived from F = m.a

We have; a = F/m

a = 12/4

a = 3

The resultant acceleration of the object is 3m/s².

The heat of vaporization of water is 2,260 J. How much energy is released when 20 grams of steam is condensed at 100°C? *
gulaghasi [49]

Answer:

45200J

Explanation:

Given parameters:

Heat of vaporization of water  = 2260J/g

Mass of steam = 20g

Temperature = 100°C

Unknown:

Energy released during the condensation  = ?

Solution:

This change is a phase change and there is no change in temperature

To find the amount of heat released;

          H  = mL

m is the mass

L is the latent heat of vaporization

 Insert the parameters and solve;

          H  = 20g x 2260J/g

           H = 45200J
