determine the percentage of water in hydrated nickel chloride crystals, NiCl2.6H2O. it is used as absorbent of amonia in gas masks​

Use the table to identify the phase and phase changes of the elements under the given conditions. write the name of the substance, phase, or phase change

Ethanol (c2h5oh) is produced from the fermentation of sucrose in the presence of enzymes. c12h22o11(aq) + h2o(g) 4 c2h5oh(l) + 4 co2(g) determine the theoretical yield and the percent yields of ethanol if 680. g sucrose undergoes fermentation and 326.5 g ethanol is obtained. theoretical _ g _ percent %

Precision can be defined as the o exact center of a data set. o reproducibility of a measured value. o correlation between two variables that are measured in a data set agreement between a measured value and an accepted value.
