Answer:
x=2.
Explanation:
Hello there!
In this case, since we have a mole ratio of moles of Cl to moles of Cu as 2.39, it is possible to write the following:
Thus, since the two possible copper chlorides are CuCl and CuCl₂, we can therefore infer that x=2 since it is close but not as close as it should to the whole number 2.
Best regards!
Answer:
53 moles of oxygen, O₂
Explanation:
The chemical equation for the reaction is presented as follows;
C₃H₈(g) + 5O₂(g) → 3CO₂(g) + 4H₂O (i)
From the above equation, 5 moles of oxygen, O₂, gas reacts completely with 1 mole of propane gas, C₃H₈
Therefore 10.6 × 5 = 53 moles of oxygen, O₂, will be required to react with 10.6 × 1 mole of propane, C₃H₈
The number of moles of oxygen, O₂, necessary to completely react with 10.6 moles of propane, C₃H₈ is 53 moles of oxygen, O₂
Explanation:
To balance half equations of a redox reaction is important to not only balance the mass (ammount of atoms of each element in both sides of the equation), but also balance the charges (ion's charges and electrons).
<u>For example: </u>
The reaction:
First step is to identify the element oxidized (loses electrons/valence increases) and the element reduced (gains electrons/valence decreases)
- Fe is oxidized (valence from +2 to +3)
- Mn is reduced (valence from +7 to +2)
So we have to half equations:
Oxidation equation
Here the mass is balanced, but the charges aren't. Balancing:
Reduction equation
<u>Balancing the mass with H2O and H+</u> (assuming acid medium)
<u>Balancing charges</u>
Global balance
Answer:
It's not "piece", it's "amount.' And the metal would first dissolve in the water and float. It forms potassium hydroxide and hydrogen gas which then react with each other. The reaction also lights the potassium metal on fire producing a lilac flame. The reaction is exothermic.
