What is sapling plus?

Sapling Plus is an online homework system and eBook that your instructor assigns to help you learn key concepts. Question types include multiple-choice, free-response, labeling, and ranking, along with hints and feedback to help you answer and learn from your mistakes.

Which reactions are not possible according to Dalton’s theory?

Which of the following chemical reactions are not possible according to Dalton’s atomic theory? All atoms must be accounted for. No atoms cannot be “lost” in a reaction. Chlorine cannot become hydrogen and creating water does not automatically bring in gold from nowhere.

Is there a relative charge of +1?

The relative mass of a proton is 1, and a particle with a relative mass smaller than 1 has less mass. The mass of electrons is very small compared to protons and neutrons….Subatomic particles.Subatomic particleRelative massRelative chargeProton1+1Neutron10Electron0.0005-1

Do atoms have mass?

Because matter is defined as anything that has mass and takes up space, it should not be surprising to learn that atoms and molecules have mass. Individual atoms and molecules, however, are very small, and the masses of individual atoms and molecules are also very small.

What has the same number of protons as fe3+?

The Fe2+ and Fe3+ ions have the same number of protons. The Cu+ and Cu2+ ions have the same number of electrons. The K+ ion is formed when a potassium atom loses one electron.

What is the charge of fe2+?

Iron(2+) is a divalent metal cation, an iron cation and a monoatomic dication….3.1Computed Properties.Property NameProperty ValueReferenceFormal Charge2Computed by PubChemComplexity0Computed by Cactvs (PubChem release 15

How many protons and electrons are in fe3+?

Electron “cloud” of orbitals Difference of number of electrons from number of protons defines the charge on an atom. For example, among atoms of iron, all with 26 protons, Fe2+ has 24 electrons and Fe3+ has 23 electrons, whereas elemental (uncharged) Fe has 26 electrons. the mass of an atom is outside the nucleus.

What is a anion?

What is an anion? An anion has more electrons than protons, consequently giving it a net negative charge. For an anion to form, one or more electrons must be gained, typically pulled away from other atoms with a weaker affinity for them.

Is Iodine a cation or anion?

What does anion mean on a fan?

An air ioniser (or negative ion generator or Chizhevsky’s chandelier) is a device that uses high voltage to ionise (electrically charge) air molecules. Negative ions, or anions, are particles with one or more extra electrons, conferring a net negative charge to the particle.
