Calculate the change in entropy of copper when converted to a gas. In the following equation, m and n are the coefficients of the products and the reactants in the balanced reaction equation. ∆S° = [Σ mS° products] – [Σ nS° reactants] To avoid clutter, I’m omitting typing in the unit J/(mol•K) in the intermediate […]

Explanation: To answer this question successfully, we need to remember that atoms are neutral species, since the number of protons, the positively charged particles, is equal to the number of electrons, the negatively charged particles. That said, we may firstly find an atom which has 3 electrons (and, as a result, 3 protons, as it

Then, Therefore, it forms 2 covalent bonds. Hope this helps ! Photon are formed by nitrogen if each of its unpaired electrons participates in one bond. Further Explanation: The bond that is formed by the mutual sharing of electrons between the bonded atoms is called a covalent bond. It is also known as a molecular

Use the value of the Avogadro constant, which is 6.02214129 x 10^23 mol-1. Find the atomic mass of the element by using the periodic table of elements. For example, the atomic mass of sulfur (S) is 32.07 g/mole. Divide the atomic mass of the element by the Avogadro constant to calculate the mass of the single
