Answer:
2.475 mol of O2 formed.
Explanation:
Given 1.65 moles of KClO3 as the target amount in the reactant, used the coefficient of the balanced chemical reaction involved to determine the number of moles of O2 molecules formed.
x mole of O2 = 1.65 mol KClO3 x [(3 mol O2)/ (2 mol KClO3)] = 2.475 mol of O2
x mole of O2 formed = 2.475 mol of O2
Carbon needs four more valence electrons, or a total of eight valence electrons, to fill its outer energy level.
Answer:
im sorry im bored can we talk
Explanation:
lol
An acid is a substance that donates hydrogen ions. Because of this, when an acid is dissolved in water, the balance between hydrogen ions and hydroxide ions is shifted. Now there are more hydrogen ions than hydroxide ions in the solution. This kind of solution is acidic.
Answer:
N2+O2→2NO
Explanation:
Dalton’s atomic theory is based on law of constant composition and law of conservation of mass.
One of the postulates of this theory is that rearrangement of atoms occurs during a chemical reaction. In other words, only rearrangement of elements occurs during a chemical reaction and elements remain the same.
So, among the given, the following reaction undergoes rearrangement of elements.
N2+O2→2NO
SO, only the above reaction is possible as per Dalton’s atomic theory.
