What makes an atom able to form a compound? * O different number of neutron than protons O unfilled outer electron shells O same number of protons as electrons O a positive ot negative charge of the nucleus

Answers

Answer 1

Answer:

Answer:

same number of protons as electrons

Explanation:

The addition of a neutron can make an atom radioactive. When you change the number of protons in an atom, you will change the atom from one element to a different element. ... If you change the number of electrons in an atom, you will get an ion of the element.

A substance that cannot be broken down into other substances by ordinary chemical procedures is a(n) __________ a) element
b) compound
c) isotope
d) proton
e) molecule

Answers

Answer:

Explanation:

An element is a substance that cannot be broken down into simpler substances using ordinary chemical procedures. To disintegrate an element, procedures like nuclear reactions needed to be used.

In fact, it was thought of that the elements are indivisible during the days of Dalton, but advances in science and technology has shown that these elements could be broken down albeit not easily

Final answer:

An element is a substance that cannot be broken down into other substances by ordinary chemical methods. It is the basic unit of all matter. Examples of elements include gold, silver, and carbon.

Explanation:

A substance that cannot be broken down into other substances by ordinary chemical methods is called an element. This is because elements are the fundamental materials of which all matter is composed. For instance, gold, silver, and carbon are examples of elements. Unlike compounds, isotopes or molecules, an element is made up of the same type of atom and cannot be decomposed into simpler substances by any ordinary chemical processes.

CO2 + H2 -> CO + H2O What is being oxidized?

Answers

Hydrogen is being oxidized in the given reaction CO2 + H2 → CO + H2O. the carbon atom in CO2 is reduced to CO, while the hydrogen atoms in H2 are oxidized to H2O.

How is that so?

Oxidation is the loss of electrons, while reduction is the gain of electrons. To determine which class is being oxidized and that is being diminished, we can equate the oxidation states of the materials in the reactants and produce.

In CO2, the element atom has an oxidation state of +4, while the oxygen atoms each have an disintegration state of -2. In H2, each hydrogen atom has an decay state of 0.

In CO, the element atom has an oxidation state of +2, while the oxygen dot in H2O has an oxidation state of -2. The hydrogen atoms in H2O each have an disintegration state of +1.

Therefore, the carbon atom in CO2 is decreased to CO, while the hydrogen atoms in H2 are oxidized to H2O.

In the following electrochemical cell, what is the reduction half-reaction? Mn(s) | Mn2+(aq) || Fe3+(aq), Fe2+(aq) | Pt(s)

Answers

In the given electrochemical cell, the reduction half-reaction occurs at the electrode on the right side of the double vertical line (||).

To determine the reduction half-reaction, we need to compare the standard reduction potentials (E°) of the species involved. The half-reaction with the more positive E° value will be the reduction half-reaction.

Looking up the standard reduction potentials in a reference table, we find that the standard reduction potential for the Mn2+/Mn couple is -1.18 V, and the standard reduction potential for the Fe3+/Fe2+ couple is +0.77 V.

Since the Fe3+/Fe2+ couple has a more positive standard reduction potential, it will undergo reduction. Therefore, the reduction half-reaction is:

Fe3+(aq) + e- → Fe2+(aq)
