Calculate ΔH° = for the chemical reaction

Chemistry
1 answer:
babymother [125]3 years ago

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

Why is a molecule of CO2 nonpolar even though the bonds between the carbon atom and the oxygen atoms are polar?
goblinko [34]
<span>The answer is 1. Carbon dioxide has two covalent bonds amid every oxygen atom and the carbon atom. When molecules are balanced, though, the atoms pull similarly on the electrons and the control distribution is uniform. Symmetrical molecules are therefore nonpolar.</span>

What causes “gaps in the rock record” and how is that described?
Mamont248 [21]

Answer:

An unconformity is a widespread surface separating rocks above and below, which represents a gap in the rock record. Unconformities occur when either erosion wears away rocks, or rock deposits never form. Therefore, a time gap exists between when the rocks below the unconformity formed and when those above it formed.
