following would decrease the rate of facilitated diffusion? decreasing the number of carrier proteins What happens to facilitated diffusion when the protein carriers become saturated? The maximum rate of transport will occur. What happened when sodium chloride was added as a solute in the left beaker? There was no change in the transport rate of glucose. Which of the following statements about carrier proteins is FALSE? They assist in simple diffusion. Which of the following statements about

very quickly with sodium and releases sodium oxide. 1. It must produce heat when it reacts‚ it must produce gases as products‚ it must react very quickly‚ and it must be stable enough so that it can be exploded in controlled manner. 2. There can be a factor such as concentration or temperature that affects the rate of the reaction tremendously so it results in an explosion 3. When the car hits something hard the NaN3 pellet is triggered and it decomposes to form sodium‚ nitrogen‚ and heat

electrodes. To understand electrolysis‚ you need to know what an ionic substance is. Ionic substances form when a metal reacts with a non-metal. They contain charged particles called ions. For example‚ sodium chloride forms when sodium reacts with chlorine. It contains positively charged sodium ions and negatively charged chloride ions. Ionic substances can be broken down by electricity. Electrolysis is the process by which ionic substances are decomposed (broken down) into simpler substances when

Alexis Becker Pre-Lab Experiment 7 Avinash Pallagani Investigating Stoichiometry with sodium salts of carbonic acid 4/2/14 A summary of the concepts: The purpose of this lab is to better understand “stoichiometry”. We will be reacting sodium carbonate (NaHCO)3 and sodium carbonate (Na2CO3) with hydrochloric acid to produce sodium chloride‚ water‚ and carbon dioxide. The balanced chemical reaction looks like this: NaHCO3 + HCl = NaCl + H2O + CO2 CAUTION: Be especially

is a common enzyme that is found in almost all living organisms exposed to oxygen. Hydrogen Peroxide and Sodium Hypochlorite Hydrogen peroxide is in bleaches too‚ but only the mild ones‚ which is the non-chlorine bleaches. Since only hydrogen peroxide isn’t very strong‚ other products usually use other chemicals to make the reaction and results more effective‚ for example; sodium

by different factors such as light intensity‚ temperature‚ amount of water and amount of CO2. Thus‚ we are investigating effect of light intensity on the rate of photosynthesis in leaf discs by varying the light intensity‚ and fixing the amount of sodium hydrogen carbonate solution and temperature. It is predicted that as the intensity of light increases‚ so will the rate of photosynthesis and the amount of oxygen produced. Reasearch question : How does different light intensity

soda is simply sodium bicarbonate‚ a substance found naturally in mineral deposits‚ oceans and lake sediments as trona ore. Sodium bicarbonate is also manufactured in the human body‚ where it helps to maintain the correct pH of the blood stream‚ neutralizes stomach acids and plaque acids‚ and carries carbon dioxide from bodily tissue to the lungs. Baking soda is a white crystalline powder (NaHCO3) better known to chemists as sodium bicarbonate‚ bicarbonate of soda‚ sodium hydrogen carbonate

When tested as a whole can be considered an eye irritant. Complex Sodium Phosphates and sodium carbonate are used as a water softener. Nonionic surfactant and chlorine bleach is a cleaning and water spot preventive agent. Sodium silicate is a dishwasher and china protection agent. Sodium sulfate has multiple jobs

Effects of Fast Food: Sodium and Increased Blood Pressure Most of these quick and convenient meals contain high amount of sodium‚ which increases and aggravates the risks of high blood pressure. According to the recommendations of the National Research Council of the National Academy of Sciences 1‚200 - 1‚500 mg of sodium is the daily sodium requirement for adults. Keeping these figures in mind‚ you should also know that the regular table salt that we consume contains 40% sodium and a single teaspoon
