Calculate ΔH° = for the chemical reaction

Chemistry
1 answer:
babymother [125]2 years ago
4 0

Answer: \Delta H^0 for the reaction Cl_2(g)+F_2(g)\rightarrow 2ClF(g)  is -108kJ

Explanation:

The balanced chemical reaction is,

The expression for enthalpy change is,

\Delta H=[n\times B.E_{reactants}]-[n\times B.E{products}]

where, n = number of moles

Now put all the given values in this expression, we get

\Delta H=[1\times B.E_{Cl_2}+1\times B.E_{F_2}]-[2\times B.E_{ClF}]

\Delta H=[(1\times 243)+(1\times 159)]-[2\times 255]

\Delta H=-108kJ

Thus \Delta H^0 for the reaction Cl_2(g)+F_2(g)\rightarrow 2ClF(g)  is -108kJ

Gnoma [55]

Answer:

1/4 or 25%

Explanation:

The Arctic region of the earth refers to that part of the earth around the north pole region. Hence, when we are talking about latitude O degrees North, the areas around this geographical location is referred to as the arctic.

Now , there is an estimated 1/4 or 25% of the world’s oil and natural gas here. Unfortunately, these are yet accessible because of the amount of ice or snow covering. With increase in technological advancements, this might be accessible in the nearest future

An ionic bond is a bond that forms between
Morgarella [4.7K]

Answer:  An ionic bond is a bond that forms between ions with opposite charges.

Explanation:

A chemical bond formed by the transfer of electrons from one atom to another is called an ionic bond.

For example, sodium has electronic distribution as 2, 8, 1 and chlorine has electronic distribution as 2, 8, 7.

In order to attain stability, sodium needs to lose 1 electron and chlorine needs to gain one electron. Therefore, sodium will transfer its one valence electron (forming Na^{+} ion) to chlorine atom (forming Cl^{-} ion) which leads to the formation of NaCl compound.

Thus, we can conclude that an ionic bond is a bond that forms between ions with opposite charges.
