The law of conservation of mass states that matter cannot be created or destroyed, which means there must be the same number atoms at the end of a chemical reaction as at the beginning. To be balanced, every element in Ni(HSO4)3 + Ca(NO3)2 = Ni(NO3)3 + Ca(H...
The Ca/Sr atoms in the image do not exhibit displacement with regard to the unit cell center, which is expected since the matrix should belong to the nonpolar Acaa space group. On the other hand, we observe many nanometer-sized features along the (001) interface distributed randomly all ...

In analogy to atoms in a free space, the electrons thus have the choice of several types of energetically nearly equivalent electronic orbitals. Thus, the charge transfer hap- pened as the Fermi level continuously shifts at the LCMO/LNO interface. The density of states (DOS) near the Fermi...
In 1974, Molina and Rowland proposed in their Nature article that the chemically inert CFC could gradually be transported up to the ozone layer, there to be met by such intensive ultra-violet light that they would be separated into their constituents, notably chlorine atoms. They calculated that...

a Al(ClO4)3 + b Ca(HCO3)2 = c Ca(ClO4)2 + d Al(HCO3)3 Step 2: Create a System of Equations Create an equation for each element (Al, Cl, O, Ca, H, C) where each term represents the number of atoms of the element in each reactant or product. A...
We have studied an internal friction (IF) peak at 400 K which appears when site A in manganite type ABO3 is partially substituted by Ca, Sr and Ba atoms. In the case of total substitution in CaMnO3, the 400 K peak is absent. The appearance and the increase of this peak measured...
To be balanced, every element in Ca(OH)2 + Cl2 + CH3CH2OH = HCOOCa + H2O + CaCl must have the same number of atoms on each side of the equation. When using the inspection method (also known as the trial-and-error method), this principle is used to bala...
To be balanced, every element in CaCl2 + KOH + KClO2 = Ca2O3 + KCl + H2O must have the same number of atoms on each side of the equation. When using the inspection method (also known as the trial-and-error method), this principle is used to balance one ele...
