active transport of sodium potassium pumps will decrease dramatically due to the lessened concentration of pumps. If the same transport was run without ATP. it would not work‚ hence justifying that it is not simple diffusion‚ and rather was active transport‚ which requires the use of ATP. No‚ because the two substances are the same in each beaker‚ causing no effect on Na+ transport as they are at equilibrium. The rate of ion transport would increase when the number of sodium-potassium pump proteins

Question 1 (Limiting Reagent) 15.00 g aluminum sulfide & 10.00 g water react until the limiting reagent is used up. [Atomic mass: H = 1.008‚ Al = 26.98‚ S = 32.07‚ O = 16.00] Here is the balanced equation for the reaction: Al2S3 + 6 H2O ( 2 Al (OH)3 + 3 H2S (i) Which of the two reactants is the limiting reagent? (ii) What is the maximum mass of H2S which can be formed from these reagents? (iii) How much excess reagent remains after the reaction is complete

increasing the rate‚ as predicted. 3. It won’t change since the concentrations are the same and the transport proteins are glucose carriers. The rate did not change because sodium chloride doesn’t help nor hinder the diffusion of glucose. Activity 3 1. The pressure will increase due to the increased concentration of sodium chloride. The pressure increased. 2. Neither one requires ATP. Simple diffusion is the movement of a solute from an area of HIGH to LOW solute concentration but osmosis

For the Barium solution the Paramecium were moving forward for about 41% of the time. When I was observing them they changed direction frequently instead of going forward for most of the time. They were still moving at an average speed. For the Sodium solution the Paramecium were moving forward for about 45% of the time. I was observing them. They changed direction frequently going in a jerking motion and a paranoid state (moving backwards.) They were still going at an average speed. For the Potassium

there were no bubbles‚ however the substance turned a yellow-white colour after a few minutes. After a longer wait‚ the substance started to precipitate and the liquid started to become more solid. In the third reaction of which Barium Chloride and Sodium Sulphate were mixed‚ bubbles were again visible‚ however there were very few. After a couple of minutes the mixture turned very cloudy‚ into a solid white colour. 10 minutes later‚ the mixture was completely clear and the compounds had very clearly

potassium compound formed by burning wood. Also during this time‚ people did not pick up on any distinctions between potassium and sodium‚ deeming them as the same element. In 1807‚ Sir Humphrey Davy discovered a difference in the two‚ therefore finding potassium. Thanks to this discovery‚ we now use potassium for a variety of things‚ such as liquid detergents‚ low-sodium salt‚ oxidizing agents‚ fireworks‚ fertilizers‚ heat- transfer medium‚ and many more.

Chapter 9 1) Approximately how much water do you need each day to stay healthy? Water constitutes 50% to 70% of the human body. Its unique chemical properties enable it to dissolve substances as well as serve as medium for chemical reactions‚ temperature regulation and lubrication (found in the knees and other joints of the body); it also aids in regulating the acid base balance in the body. It helps remove waste from the body and is the basis for saliva‚ bile and amniotic fluid. It is
