Answer:
2 to 1
Explanation:
The reaction equation is given as:
2KHCO₃ → K₂CO₃ + CO₂ + H₂O
The conversion factor between the moles of KHCO₃ and K₂CO₃ is 2 to 1.
From the balanced chemical equation, we find out that;
2 moles of 2KHCO₃ will produce 1 mole of K₂CO₃.
So given any mole of either of the reactant or product, we can find the unknown.
Answer:
it would be 4.5 mole left over
Explanation:
Answer:
Option 3 is correct.
The atomic nucleus of each element has a unique number of protons. Therefore, the energy of the electron layers of the atoms of each element is unique.
If we have the energy released from each electron transfer between the layers of the atom, we can identify the element.
