A diatomic gas is a gas that can only exist when two of its atoms are bonded together. It cannot exist as a single atom. Examples of diatomic gases are chlorine gas, nitrogen gas and oxygen gas.Answer and Explanation: Chlorine gas is a diatomic gas. This means that it can...
Atoms are made up of protons, neutrons, and electrons. The protons and neutrons are found in the nucleus of the atom, while the electrons are outside the nucleus. The atomic number is the number of protons, while the mass number is the number of protons and neutrons. If an element is ...
Oxidation State and Numbers of CH3CH2CCH3CH3Cl (Tert-amyl Chloride) To calculate the oxidation numbers for CH3CH2CCH3CH3Cl, count the number of atoms, draw the lewis structure by adding bonds, assign electrons from each bond, and count the number of electrons assigned to each atom. Count ...

Kwan Chi Kao, in Dielectric Phenomena in Solids, 2004 1.4.8 The Chemical Unit of Mole The definition of Avogadro's number of 6.022 × 1023/mole is the number of atoms or molecules per one gram atomic weight. For one gram atomic weight of hydrogen with atomic weight of one gram, one mo...
How many protons are in chlorine? How many neutrons are in chlorine? What is the gram molecular mass (gmm) of chlorine? What is the density of chlorine gas? How many atoms of chlorine are in 2.00 mol of chlorine gas? What is the mass number for bromine?
19 found that Ru clusters favored CH4 formation in contrast to Ru single atoms. Due to the limited ability to activate hydrogen, single Ru atoms can only allow CO formation but cannot further hydrogenate it to CH4. However, we find later that the modulation of the chemical state of metal ...
