<span>Africa was more south and west and South America was more south and east of their current positions. I would say this would be because because South America and Africa used to be together in Gondwanaland millions of years ago and then apparently drifted apart as Wegener thought and then with the advent of plate tectonics it became apparent that the mid-Atlantic ridge runs between them and due to spreading along it Africa and S America got separated.</span>

Please show some work For the reaction: NO(g) + 1/2 O2(g) → NO2(g) ΔH°rxn is -114.14 kJ/mol. Calculate ΔH°f of gaseous nitrogen
natulia [17]

Answer: ΔH°f of gaseous nitrogen monoxide is 148.0 kJ/mol

Explanation:

The balanced chemical reaction is,

NO(g)+\frac{1}{2}O_2(g)\rightarrow NO_2(g)

The expression for enthalpy change is,

\Delta H_{rxn}=\sum [n\times \Delta H_f(product)]-\sum [n\times \Delta H_f(reactant)]

\Delta H_{rxn}=[(n_{NO_2}\times \Delta H_f_{NO_2})]-[(n_{O_2}\times \Delta H_f_{O_2})+(n_{NO}\times \Delta H_f_{NO})]

where,

n = number of moles

\Delta H_{O_2}=0 (as heat of formation of substances in their standard state is zero

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

-114.14=[(1\times 33.90)]-[(\frac{1}{2}\times 0)+(1\times \Delta H_f{NO})]

\Delta H_f{NO}=148.0kJ/mol

Therefore, ΔH°f of gaseous nitrogen monoxide is 148.0 kJ/mol

Please help me in this.<br> i'll seriously mark you brainly. <br> please help.
Bingel [31]

Answer:

First box: 3

Second box: 4

Third box: 3

Fourth box: 4

Explanation:

I tried out various numbers, but got 3 and 4 because:

3PbI4 + 4CrCl3 -----> 3PbCl4 + 4CrI3

Each term cancels put.

3Pb --> 3Pb

4Cr --> 4Cr

and so forth...

Hope this helps!
