lot like the first definition we gave‚ where an acid breaks up and releases/donates a hydrogen ion. This newer definition is a little bit more detailed. Scientists used the new definition to describe more bases‚ such as ammonia (NH3). Since bases are proton acceptors‚ when ammonia was seen accepting an H+ and creating an ammonium ion (NH4+)‚ it could be labeled as a base. You didn’t have to worry about hydroxide ions anymore. If it got the H+ from a water molecule‚ then the water (H2O) was the proton

I. INTRODUCTION Background of the Study Most of the Filipinos earn a living through agriculture. Throughout the years‚ a lot of fertilizers were improvised‚ mostly for the comfort of the Filipino farmers. Human urine‚ for example‚ is a well-balanced nitrogen-rich quick-reacting liquid fertilizer. It contains nitrogen‚ potassium and phosphorus and other nutrients depending on the diet. The health risks associated with use of human urine in plant production are generally low‚ that is why it’s an

which is 0.613 mm/min. Thus the lighter the molecular weight‚ the faster is the rate of diffusion. INTRODUCTION As we open a household ammonia it will not take that long before the smell of it occupies the whole room. The gaseous molecules travel quickly and mix with the molecules in the air which makes it possible for people to immediately smell the ammonia as soon as it is opened. Such process is known to be the diffusion (Myers‚ Oldham and Tocci‚ 2006). Gases tend to diffuse rapidly with each

and it was due to me neglecting the water level. All of the other fish in both batches survived. 6. Study the data you collected. Describe the occurrences of ammonia‚ nitrite‚ and nitrate in your tank. I cycled the tank during weeks 3 to 7. First‚ there was ammonia‚ then nitrite‚ and then nitrate. Currently‚ the ammonia and nitrite levels of my tank are 0. 7. Study the data you collected. Why is the population in

Topic 11a – Group 7‚ the Halogens Revision Notes 1) Trends in physical properties of the elements • At room temperature‚ Cl2 is a pale green gas‚ Br2 is a brown liquid‚ I2 is a blue-black solid. • In Group 7‚ boiling point increases down the group because the molecules have more electrons and‚ therefore‚ stronger van der Waal’s forces which require more energy to overcome them • Electronegativity is the ability of an atom to attract the electrons in a covalent bond • Down

Medium formulation is an essential stage in the design of fermentation process. Most fermentation media require liquid media‚ although some solid-substrate fermentations are also operated. Fermentation media must satisfy all the nutritional requirements of the microorganisms and fulfill the technical objectives of the process. There are several stages where media are required in a fermentation process; inoculum (starter culture)‚ propagation steps‚ pilot-scale fermentations and the main production
