What is the formula for carbon monoxide? What is hydrogen sulfide? What is the atomicity of halogens? Which halogens are gases at STP? What is a monatomic gas? Which diatomic element contains triple covalent bond? What is lactose's chemical formula?
Explain why the noble gases tend to be monatomic rather than diatomic. Explain why a soft-iron core increases the strength of an electromagnet. Why does increasing the temperature of a magnet decrease its magnetism? Why did the solar nebula flatten into a disk? Why nanoparticles have...
When calculating thermodynamic properties for 1 mole of a monatomic gas, we use the mass of a single atom, not the mass of a mole of atoms. Explain why. What is the overall energy change of a system if a chemical reaction transf...
A 5.0-liter gas tank holds 2.0 moles of helium (monatomic) and 0.6 moles of oxygen (diatomic), at a temperature of 390 K. The atomic masses of helium and oxygen are 4.0 g/mol and 16.0 g/mol, respectively. The ratio of the rms...
Explain why the noble gases tend to be monatomic rather than diatomic. Suntanning produces cell damage in the skin. Why is ultraviolet radiation capable of producing this damage, while visible radiation, even if more intense, is not? Why does helium have more spectral lines...
The kinetic theory of gases is used to describe the gases' behavior as the temperature increases or decreases. As the temperature of the gases increases, the kinetic energy of the gases also increases. Answer and Explanation: The pressure p exerted by a gas ...
