What is the net ionic equation for the reaction between aqueous sodium hydroxide (NaOH) and aqueous nitric acid (HNO 3 )?

H + (aq) + OH - (aq) → H 2 O( l )

H + (aq) + NO 3 (aq) + Na + (aq) + OH (aq) → H 2 O( l ) +Na + (aq) + NO 3 (aq)

HNO 3 (aq) + NaOH (aq) → NaNO 3 (aq)

Na + (aq) + NO 3 (aq)→NaNO 3 (aq)

HNO 3 (aq)+OH (aq)→H 2 O( l ) + NO 3 (aq)

The combustion of methane (CH 4 ) produces carbon dioxide (CO 2 ) and steam (H 2 O). All of the following statements concerning this reaction are correct EXECPT

one gram of carbon dioxide is formed per two grams of oxygen consumed.

one molecule of carbon dioxide is formed per one molecule of methane consumed.

two molecules of oxygen are consumed per one molecule of methane consumed.

two moles of steam are formed per two moles of oxygen consumed.

the combined mass of reactants consumed equals the mass of products formed.

Hund's rule states that the most stable arrangement of electrons (for a ground state electron configuration)

has the maximum number of unpaired electrons, all with the same spin.

has a filled valence shell of electrons.

has two electrons per orbital, each with the same spins.

has ml values greater than or equal to zero

has two elecctrons per orbital, each with opposing spins.

Explain why the following is not a formation reaction. 4Na(s)+O(g)→2NaO(s)

Two moles of the compound are formed

The standard state of oxygen is O(g).

Gases can only be on the product side.

The product is not an element. 0 an

Without doing a calculation, predict which of the following shows a decrease in entropy?

CO(g)+2H 2 (g) → CH 3 OH( l )

2 HNO 3 (l) + NO(g)→3NO 2 (g) + H 2 O(l)

FeCl 2 (s) + H 2 (g) →Fe(s) +2HCl(g)

2H 2 O(g) + →2H 2 (g) + O 2 (g)

CH 3 OH(l) + 3/2 O 2 (g)→2H 2 O(g) + CO 2 (g)

Select the correct statement that corresponds to the second law of thermodynamics.

In any spontaneous process, ΔS universe = ΔS system + ΔS surroundings >0

he standard Gibbs free energy change, ΔG o , can be calculated from Gibbs free energies of formation, ΔG f o

The entropy of a perfect crystal of any pure substance approaches zero, as the temperature approaches absolute zero (0 K)

The entropy change for a reaction, ∆S o , can be calculated from the standard molar entropies of the reactants and products

ΔE universe = ΔE system + ΔE surroundings = 0

If a 5.0 L flask holds 0.125 moles of nitrogen at STP, what happens to the entropy of the system upon heating the gas to 75 °C?

There is too little information to assess the change
