Answer: options C and D

Explanation: in Redox reaction (oxidation-reduction), oxidation numbers of Reactant and product are different.

In oxidation, oxidation state increases and decreases in the case of Reduction.

In C, oxidation state of C is increased from +3 in C3H6 to +4 in CO2 hence oxidation and oxidation of O2 Decreased from 0 to -2 in H2O, hence Reduction. So it is a redox reaction

Similarly in D, Fe: +3 to 0

Carbon : +2 to +4.

The last two.

2C3H6(g)+9O2(g)-> 6CO2(g)+6H2O(g)
Fe2O3(s)+3CO(g)-> 2Fe(I)+3CO2(g)

What is the ΔG for the following reaction at 25°C?

ikadub [295]

$\Delta G_{global}=\Delta G_{products}-\Delta G_{reagents}\\\\
\text{We should consider the stoichiometry:}\\\\
\Delta G=2\Delta G_{NO_2}-\Delta G_{N_2O_4}\\\\
\Delta G=2\cdot51.8-98.28=103.6-98.28\\\\
\boxed{\Delta G=5.32~kJ}$

Consider an electron with charge âˆ’eâˆ’e and mass mmm orbiting in a circle around a hydrogen nucleus (a single proton) with cha

PtichkaEL [24]

Answer:

Explanation:

The net force on electron is electrostatic force between electron and proton in the nucleus .

Fc = $\frac{1}{4\pi\epsilon} \times \frac{e\times e}{r^2}$

This provides the centripetal force for the circular path of electron around the nucleus .

Centripetal force required = $\frac{m\times v^2}{r}$

$\frac{m\times v^2}{r}=\frac{1}{4\pi\epsilon} \times \frac{e\times e}{r^2}$

$v^2=\frac{e^2}{4\pi \epsilon m r}$

$v=(\frac{e^2}{4\pi \epsilon m r})^{\frac{1}{2} }$
