P2H2 Oxidation State - Diphosphene

P2H2 has an oxidation number of +1. In P2H2, the oxidation

number of H is -1

H2C2O4 Oxidation State - Oxalic Acid

C has an oxidation number of +3 in H2C2O4. O has an oxidation

number of -2 in H2C2O4. H2C2O4 has an oxidation number of +1.

CrO2 Oxidation State - Chromium(IV) Oxide

CrO2 has an oxidation number of +4.

<h3>Explain oxidation?</h3>

The oxidation state, also known as the oxidation number, is an atom's hypothetical charge if all of its bonds to other atoms were fully ionic.

The sum of the oxidation states of all the atoms in an ion equals the ion's charge.

A substance's more electronegative element is given a negative oxidation state. The one that is less electronegative is given a positive oxidation state.

Represent the formation of cations for the following metal atoms using electron dot structures. (a) Al (b) Sr (c) Ba

vagabundo [1.1K]

the formation of cations by using electron dot structures are :

a) Al

Al . losing the three valence electrons makes the Al³⁺

b) Sr :

Sr : losing the two valence electrons makes Sr²⁺

c) Ba

: Ba , losing the two valence electrons makes it Ba²⁺

A Lewis electron dot diagram is a representation of the valence electrons of an atom that employments specks around the image of the element. The number of dots equals the number of valence electrons within the molecule. These dots are arranged to the right and left and over and underneath the symbol, with no more than two dots on a side. Cations are the positive ions shaped by the loss of one or more electrons. The foremost commonly shaped cations of the representative elements are those that include the loss of all of the valence electrons.

When does a star reach equilibrium?

Snezhnost [94]

Actually, that does not happen until the protostar becomes a star when nuclear ignition starts and is maintained. It takes awhile for new star to go through its T-Tauri stage and settle down on the main sequence.

<span>A STAR does not reach hydrostatic equilibrium until it on the main sequence. Otherwise, it would remain a brown dwarf with not enough mass to to maintain nuclear fusion for more than 3,000 to 10,00 years. </span>

This equation shows a ____ refer to this summary equation of photosynthesis to complete the sentences about chemical bonds and r

coldgirl [10]

The balanced chemical equation representing the process of photosynthesis is:

$6 CO_{2} +12H_{2}O-->C_{6}H_{12}O_{6}+6O_{2}$

The reactants in the process of photosynthesis are $CO_{2}$ and H $H_{2}O$ and the products of the reaction are glucose $C_{6}H_{12}O_{6}$ and oxygen $O_{2}$ . Oxygen is the nonpolar covalent gas which is released in the process of photosynthesis. The reactant $CO_{2}$ is a nonpolar covalent gas while the other reactant water $H_{2}O$ has polar covalent O-H bonds.
