Which best describes stellar equilibrium.

Equation 13.4.4 suggests that if we heat CaCO 3 to a high temperature so that some of it decomposes, the concentration of CO 2 at equilibrium will depend only on the temperature and will not change if the ratio of amount of solid CaCO 3 to amount of solid CaO is altered. Experimentally this is what is observed.Stellar nucleosynthesis is the process by which elements are formed within stars. The star formation theory proposes that stars form due to the collapse of the dense regions of a molecular cloud. A protostar is a stellar core formed when the fragments of a collapsed molecular cloud contract.Final answer. Select all the true statements regarding chemical equilibrium. At equilibrium... the concentrations of reactants and products are equal. the concentrations of reactants and products remain constant. reactants are still being converted to products (and vice versa). the rates of the forward and reverse reactions are equal.Stellar nucleosynthesis is the process involving nuclear reactions through which fresh atomic nuclei are synthesized from pre-existing nuclei or nucleons.

Terms in this set (18) Stars release huge amounts of radiation from their surfaces while on the main sequence. Why is this necessary if a star is to maintain hydrostatic equilibrium? - Fusion in the core generates huge amounts of energy which must be radiated away. - If the energy were not radiated away, the balance would be upset and the star ...The universe appears to be expanding. When a certain type of star begins to die, its core temperature rises. This causes helium to fuse into carbon and oxygen. Sometimes the temperature of this type of star does not rise high enough for the carbon and oxygen to fuse. If this occurs, which of these will be the final stage of this star? white dwarf.

static equilibrium (3). Hydrostatic equilibrium implies a local balance between pressure and gravity, can be expressed as: dP dr Gmρ r2 (1) where P is the pressure, ρis the density, and m is the mass contained inside the radius r. To describe this condition in detail, one must specify the temperature, density, and composition of the stellar ...A stellar equilibrium is a state of balance in which a star’s internal pressure is equal to the weight of the star’s material and the star’s luminosity is equal to the rate at which energy is being generated by nuclear reactions in the star’s core. Insolvay Conference 1958: 97–148, December 3-5, 1958.

Which best describes dynamic equilibrium? There is a difference in concentration on either side of the cell membrane. There is an uneven distribution of particles inside and outside the cell. Particles are moving into and out of the cell, but their concentrations remain stable.The equilibrium concentration of \(O_2\) is a constant and does not depend on the amount of \(HgO\) present. Hence adding more \(HgO\) will not affect the equilibrium concentration of \(O_2\), so no compensatory change is necessary. \(NH_4HS\) does not appear in the equilibrium constant expression because it is a solid.The Stellar Spectral Sequence as a Temperature Sequence.
