The main goal of of of this project was to to determine the the the effect of of of different cross-sectional areas of of of of the the the the tools on on on the the the the evaporation rate of of sodium chloride salt from the the the Dead Sea
This effect was studied in three solutions with different concentrations at at at at at two temperatures temperatures 25°C and and 45°C The results showed that with increased increased cross-sectional areas and and temperatures temperatures the evaporation rates increased increased Keywords: concentration cross-sectional areas density evaporation rate sodium chloride Research on on molybdenum trioxide as a a a a a a catalyst for water reduction

Hydrogen can be used as as as an an alternative to fossil fuels In this project molybdenum trioxide was studied as as as a a a a a a a a a a a a a catalyst for water reduction
to produce hydrogen hydrogen The rate and the amount amount of of of hydrogen hydrogen released were tested for three parameters: pH of of of of the the the solution amount amount amount of of of of molybdenum trioxide and the the the amount amount amount of of of of sodium borohydride The results indicated that the the the amount amount and rate of of hydrogen release in in in an an an acidic solution is larger than in in basic conditions It may be concluded that molybdenum trioxide serves as as as a a a a a a a a a a a catalyst for the release of hydrogen hydrogen under acidic conditions Keywords: catalyst hydrogen hydrogen molybdenum trioxide sodium borohydride 100
