Achemical equation is shown below. kno3 → kno2 + o2 what are the coefficients that should be added to balance this equation? use complete sentences to explain your answer. explain how this chemical reaction demonstrates the conservation of mass.

The coefficient '2' must be added infront of and in order to balance a chemical reaction.

Explanation:

Law of conservation of mass states that the mass can neither be created nor be destroyed, but it can only be transformed from one form to another. It always remain conserved.

In a chemical reaction, the number of individual atoms on the reactant side must be equal to the number of individual atoms on the product side. All the balanced chemical reactions follow law of conservation of mass.

For the given chemical reaction, the balanced equation follows:

On reactant side:

Number of potassium atoms = 2

Number of nitrogen atoms = 2

Number of oxygen atoms = 6

On product side:

Number of potassium atoms = 2

Number of nitrogen atoms = 2

Number of oxygen atoms = 6

Thus, the coefficient '2' must be added infront of and in order to balance a chemical reaction.

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
