ALKALINE EARTH METALS what are alkaline earth metals? Alkaline earth metals are elements that are in the second group of the periodic table. the elements have two electrons on the outermost shell. the elements include Beryllium‚ magnesseum‚ calcium‚strontium‚ barium and Radium.The alkaline earth metals are all silvercolored and soft‚ and have relatively low densities‚ melting points‚ and boiling points. In chemical terms‚ all of the alkaline metals react with the halogens to form the alkaline earth metal halides

Let’s Make Salt Purpose: Could NaCl be made using NaHCO3‚ hydrochloric acid‚ and a boiling chip? Hypothesis: If I combined NaHCO3‚ hydrochloric acid‚ and a boiling chip I think it will form NaCl because when you balance the equation it makes a new chemical reaction. Materials needed: test tube cleaner‚ test tube‚ test tube tongs‚ hot plate‚ a scale‚ graduated cylinder‚ water‚ goggles‚ fire retardant glove‚ beaker‚ test tube holder‚ a scoopula‚ hydrochloric acid‚ sodium bicarbonate‚ soap‚ pipette

(4) Christy Chan (5) BIOLOGY LAB REPORT Investigation of the effect of metal ions on enzyme activity Objective To study the effect of two heavy metal ions‚ lead (II) ions and silver ions on the enzyme activity of invertase. Introduction Hypothesis: The rate of enzyme reaction of invertase decreases and the reaction eventually stops as the heavy metal ions inhibit the enzyme reactions. Biological principle: Heavy metal ions are non-competitive inhibitors. They do not compete with the substrates

The litmus paper and the pH probe determined the salt solutions’ pH levels. When the blue litmus paper was dipped into ammonium chloride‚ the paper was changed to red whereas the red litmus paper stayed the same indicating that the solution was acidic. PH levels shown through pH probe also ranged between 5.5 to 6.0. Yet when in the presence of sodium acetate blue litmus stayed blue whereas red litmus turned blue‚ indicating its basicity. pH probe also showed the solution’s pH varied between the
