When comparing the two elements ga and as , the element with the higher first ionization energy is as based on periodic trends a

Nataliya [291]

He, ne , Ar - Noble gas elements have the highest ionization energy,
while francium (87) has the lowest ionization energy because it is so far from helium, in short atom near to helium has higher ionization energy and the atom who is far away from helium have low ionization energy.
Please let me know if you have any questions

For the reaction 2NH3(g) + 2O2(g)N2O(g) + 3H2O(l) H° = -683.1 kJ and S° = -365.6 J/K The standard free energy change for the rea

Answer:

$\Delta G^{0}$ = -457.9 kJ and reaction is product favored.

Explanation:

The given reaction is associated with 2 moles of $NH_{3}$

Standard free energy change of the reaction ( $\Delta G^{0}$ ) is given as:

$\Delta G^{0}=\Delta H^{0}-T\Delta S^{0}$ , where T represents temperature in kelvin scale

So, $\Delta G^{0}=(-683.1\times 10^{3})J-(273K\times -365.6J/K)=-583291.2J$

So, for the reaction of 1.57 moles of $NH_{3}$ , $\Delta G^{0}=(\frac{1.57}{2})\times -583291.2J=-457883.592J=-457.9kJ$

As, $\Delta G^{0}$ is negative therefore reaction is product favored under standard condition.

topjm [15]

Answer:

NaNO₃

KNO₃

Ca(NO₃)₂

Explanation:

The possible cations for the salt. = Na⁺ , K⁺ , Ca²⁺

The anion for which the formula has to written = NO₃⁻

The salt is of white color.

The possible salts may be:

NaNO₃

KNO₃

Ca(NO₃)₂

Missy Mae can have one of these salts.

The color of NaNO₃ is from transparent to white.

The color of KNO₃ is white.

The color of NaNO₃ is from white to light grey.

What can be added to an atom to cause a nonvalence electron in the atom to temporarily become a valence electron?

KengaRu [80]

Energy would be needed to cause an electron to be a valence electron.

Mass cannot be created nor destroyed as the law of conservation of mass states.
