H2o only has one oxygen molecule. so +o2 should just be +o

Answer:

To make H2O, you need two H and one O. in this equation, you are given two Os which is too many. you'll end up with an extra O. H2 + O2 -> H2O + O

Which of the following is best described as an acid-base reaction?
seraphim [82]

The reaction which represents an acid-base reaction is: HNO3(aq) + NH3(aq) → NH4*(aq) + NO3(aq).

<h3>What is an acid-base reaction?</h3>

An acid-base reaction is a reaction in which a substance donate protons to another substance which then accepts the proton.

An acid-base reaction usually involves the formation of a salt.

From the given reactions, the acid-base reaction is given below:

  • HNO3(aq) + NH3(aq) → NH4*(aq) + NO3(aq)

In the given reaction, HNO3 donates a proton and NH3 accepts the proton.

Therefore, the reaction which represents an acid-base reaction is: HNO3(aq) + NH3(aq) → NH4*(aq) + NO3(aq).

sarah measures out 151 grams of SO2. how many moles is this? Express your answer to three significant figures. ​
svp [43]

150 g SO₂ = 2.36 mol SO₂


M_r = 32.06 + 2×16.00 = 32.07 + 32.00 = 64.06


Moles of SO₂ = 151 g SO₂ × [1 mol SO₂/64.06 g SO₂] = 2.36 mol SO₂

When a negatively charged species is most appropriately depicted as a hybrid of several resonance forms, the negative charge pre
Varvara68 [4.7K]

Answer:

True

Explanation:

Resonance is a concept that was introduced when it was not possible to represent a compound with a single Lewis structure. Lewis formulas represent localized electrons, either shared by two atoms in a covalent bond or as non-shared electrons belonging to a given atom. Certain organic compounds, especially those containing multiple bonds can be described by more than one Lewis structure. In these cases, the true Lewis structure has an electronic distribution that is a "hybrid" of all possible Lewis structures of that molecule. Each of Lewis's structures is known as resonance or canonical forms and they are related to each other by a double-headed arrow, where all possible positions of electrons in that molecule are represented.

This type of compound has multiple bonds (double or triple) where electrons are not fixed, but move quickly between atoms, "resonating" between the different Lewis structures. For this reason, when a resonance hybrid has a negative charge, this charge moves between the different resonant structures.

Many times, an intermediate Lewis structure is drawn, with dotted lines, simulating approaching the real structure of the compound, and where this phenomenon of electron and charge mobility can be observed. For example, as we can observe in the ozone resonance image.
