The balanced half-reaction: Cr²⁺⁺(aq) → Cr⁴⁺(aq) + 2e⁻.
Chromium(II) cations two electrons and became chromium(IV) cations.
<span>Oxidation
reaction is increasing of oxidation number of element, because element or
ion lost electrons in chemical reaction.
</span><span>Reduction is lowering
oxidation number because element or ions gain electrons.</span>
Answer:
AgCl + NaNO3 would be the products of the reaction between sodium chloride and silver nitrate.
The stoichiometry of this reaction is written below, and it is because for this reaction to be fulfilled the products have to be in equilibrium with the reactants, since the mass in the reaction is conserved and must be balanced in the amount of molecules that they react to each other.
Explanation:
NaCl + AgNO3 -------------- AgCl + NaNO3
Answer:
Electromagnetic Wave Medium Matter:The ability to move or change an object, or what a wave
Longitudinal Wave Trough Rarefaction: The area in a longitudinal wave where the particles are close together.
Transverse Wave Energy Wavelength: The highest point of a transverse wave

The amount is always constant. The answer is letter A. The carbon atom is recycle in the biosphere. It may take different forms but it is still the same carbon atom. Carbon in fuel may turn into carbon dioxide or carbon monoxide after it it burned. The CO2 may then be used up by the plants as fuel to make another form of carbon based compounds such as sugar (glucose). For more information, I suggest looking up the carbon cycle.
