WebJul 21, 2024 · You cannot change subscripts in a chemical formula to balance a chemical equation; you can change only the coefficients. Changing subscripts changes the ratios of atoms in the molecule and the resulting chemical properties. For example, water (H 2 O) and hydrogen peroxide (H 2 O 2) are chemically distinct substances. WebApr 1, 2024 · And, the chip reduction coefficient of PM(S1) and GM(S2) can be reduced by amount of 2.76 % and 4.82 %, respectively. According to Ganesh et al. [27], the chip reduction coefficient reduces mean that the chip thickness after cutting is reduced, thus reducing the cutting load and energy consumption. Moreover, the variation of chip …
