acid is reacted with the rocks to generate CO2. Calcium carbonate minerals contained within the rocks of Mars have quantities of CO2 which can be extracted using a double displacement reaction. Calcium Carbonate is an alkali‚ and when mixed with an HCI generates CO2. During the reaction hydrogen combines with one oxygen part of the Calcium Carbonate to produce H2O. Calcium reacts with the water element to produce an aqueous solution of Calcium Chloride CaCl2‚ therefor leaving Carbon and Oxygen to

Hypothesis: To determine the effects of pH on catalase enzyme activity and as you increase the pH the more oxygen that will be produced. Materials: 1. 5 clean test tubes 2. HCI (acid) 3. Dilute HCI 4. Water 5. NaOH (base) Procedure: We start to fill test tube 1 4drops of HCI (acid)‚ test tube 2 dilute HCI 1 drop and 3ml water‚ test tube 3 add 4 drops of NaOH (Base) ‚ test tube 4 dilute NaOH 1 drop and 3ml water‚ test tube 5 add 3 drops of water (neutral). We filled each tube with the

The different components include the cultural dimensions‚ the ethical implications‚ the human computer interaction (HCI) and technological considerations. This report includes a brief study of HCI including user centred design process. According to ethical and culture issues we have discussed and thoroughly followed.

Technological advantages and major events that influence our current HCIS practices will also be included. Comparisons and Contrasts In the early 1990s‚ physician offices were mainly using paper-based patient records stored in filing cabinets. These records were locked with limited access to these records. Physicians
