The number of equivalents (n) can be calculated using the formula:Number of equivalents=Number of moles×n-factor Here, the number of moles of copper is 1 (from Step 1), and the n-factor for copper (Cu²⁺) is 2 (since it gains 2 electrons). Therefore:Number of equivalents=1 ...
A mole can be defined as the gram formula mass of a substance or the atomic mass of an element in grams. In this experiment, electron flow (amperage or current) and time are measured in order to obtain the number of electrons passing through the electrochemical cell. The number of atoms ...
The concentration of a solute in solution is the amount of that solute per unit volume of solution. It can be expressed as the mass of the solute per unit volume or the number of moles of solute per unit volume. A mole of any substance is Avogadro's number of particles. The ...
Electrons have a negative charge of -1 and an atomic mass of essentially 0 atomic mass units. They are so small that they are essentially without mass. They travel outside the nucleus of an atom in distinct routes called orbitals. Neutrons have no charge and have an atomic mass of about ...
2Na O → 2Na +1 + H 2 Answer: Na Note: 2e ─ are attached to hydrogens Sample Question: Given the balanced equation: 2Al (s) + 6H + (aq) → 2Al +3 (aq) + 3H 2(g) When 2 moles of Al (s) completely reacts, what is the total number of moles of electrons transferred fr...
For atomic s states, the probability density |\psi |^2 is the largest at the origin, yet the probability of finding the electron at a distance r from the nucleus, given by P(r), goes to zero with r. Explain. What is the maximum number of electrons that can occupy th...
