Which of the following does NOT demonstrate the law of conservation of matter?
Brrunno [24]

The one that does not demonstrates the law of conservation of matter would be the third option: 2NO_2 + H_2O -- > HNO_3 + HNO_2

<h3>What is law of conservation of matter? </h3>

It is a law that explains that matters are conserved during the course of chemical reactions. They can neither be destroyed nor created.

Thus, the number of moles of the species in a reaction remains the same before and after the reaction.

Thus, an equation that demonstrates the law of conservation of matter will be balanced in terms of the number of moles of species.

The only equation, in this case, is 2NO_2 + H_2O -- > HNO_3 + HNO_2

There are 3 oxygen species on the reactant while 5 are present on the product side.

Based on the number of valence electrons indicated by its location in the periodic table, which element's behavior would you pre
katrin [286]

Answer:

D

Explanation:

Elements in the same group (vertical columns) have the same number of valence electrons. These elements behave similarly because they will either give up or take the same number of electrons to fill their valence shell. Since potassium has 1 valence electron, it will most likely give up one electron. Out of all of the answer options, the only element that is in the same group as potassium is francium.
