    The balanced reaction is Ba (OH)2 + 2 NH4Cl ----------> BaCl2 + 2 NH3 + 2H2O Given reaction is as under:- Ba(OH)2+NH4Cl---->BaCl2+NH3+H2O As two chlorine atoms are present on the right hand side so multiply NH4Cl by 2 for getting equal number of Cl atoms on both the sides. reaction becomes Ba(OH)2+2NH4Cl---->BaCl2+NH3+H2O Now on the left side two nitrogen atoms are present so multiply NH3 by 2. Now the reaction will be Ba(OH)2+2NH4Cl---->BaCl2+2NH3+H2O. 10 Hydrogens are present on the left hand side so multiply H2O by 2 on the right hand side. Ba(OH)2+2NH4Cl---->BaCl2+2NH3+2H2O. Oxygens are equal on both the sides.

    a body’s characteristics allows it to serve as ideal theoretical standard compared to all real radiating bodies. This is better known as black body radiation

    1Thank You

    Nancy Rajput 7 years, 5 months ago

    A black body is an idealized physical body that absorbs all incident electromagnetic radiation. The thermal radiation from a black body is energy converted electrodynamically from the body's pool of internal thermal energy at any temperature greater than absolute zero. It is called blackbody radiation and has a frequency distribution with a characteristic frequency of maximum radiative power that shifts to higher frequencies with increasing temperature. The answer to Planck’s law of black body radiation

    1Thank You

    Larina S 7 years, 5 months ago

    A black body is an idealization in physics that pictures a body that absorbs all electromagnetic radiation incident on it irrespective of its frequency or angle. ... The Planck radiation law explains the various electromagnetic radiations emitted by a black body at thermal equilibrium at a fixed temperature.

    Atomic spectra is the spectrum of radiation absorbed or released due to transitions between energy levels in an atom.Atomic spectra is based on the fact that an electron can move between shells. When an atom absorb energy, it get excited from ground state to excited state, the energy absorbed by the atom form absorption spectra while energy released by the atom on returning to ground state form emission spectra.

    But water has fixed molarity at normal density

    0Thank You

    Priya Dharshini ? 7 years, 5 months ago

    The molarity of water depends on the temperature. We know, Water density is = 1 gram/mL. So, our liter has 1,000 grams of mass. Grams have a relationship with moles, via the molar mass of a molecule.
