Flowers vary in size from 1 inch to 2 inches in diameter. It is a perennial aquatic plant whose long stems creeping over mud or shallow water. It came from South America to the U.K. It is introduces as ornamental and water garden plant. It is first recorded in 1999. The creeping water primroses can cause a lot

Lab activity 1: Effect of temperature‚ concentration‚ and pressure on equilibrium Introduction Our ongoing discussion has been on systems at dynamic equilibrium: for a reversible reaction‚ the rate of the forward reaction is equal to the rate of the reverse reaction. What happens if equilibrium is disturbed? In this lab activity‚ we are going to examine the effect of changing reaction conditions on the position of equilibrium. Part I: Effect of temperature We will consider the equilibrium

Over the centuries‚ immigration has benefited the United States for the use of slavery‚ but what about for the economy or just the country itself? The US has been given the name‚ “The Boiling Pot‚” because we have a lot of different races combined into one country. Have you ever wondered how the boiling pot could’ve just been some scrap metal if immigrants hadn’t come into the United States and built it a little? Some people think that immigrants just want to steal our jobs‚ but do they really? Maybe

Salt Case Study Salt and Food We all need a little salt because it helps keep your body fluids at the right concentration. However‚ the majority of us eat more salt than we need. On average‚ people in the UK eat about 8.1g of salt a day. Even though it doesn’t sound like a lot‚ to reduce the risk of disease‚ adults should not be eating more than 6g of salt per day. A main source of salt is table salt. Your body only needs 1/4 teaspoon of salt every day. Salt is naturally found in foods but

Katie Paez Marine Science Salt Marsh Essay Salt marshes play vital roles in coastal areas‚ such as Westhampton‚ Southampton‚ Hampton Bays‚ and many other locations. Let’s look at the global effects of salt marshes. A study from September of this year published in UVAToday shows that the carbon stored in salt marshes may help in slowing global climate change. Carbon dioxide is the predominant so-called “greenhouse gas” that acts as sort of an atmospheric blanket‚ trapping the Earth’s heat. Over

How does the temperature of water affect how fast sugar can dissolve? Predict We will do three different tests‚ dissolving the water in boiling‚ warm and cool water. The sugar in the boiling water will dissolve the fastest. The sugar added to the cool water will dissolve the slowest. Reason According to the state of matter theory‚ the particles in a gas move faster than in a liquid‚ which I will use to infer that the hotter the water is and closer to a gas‚ the faster the particles move. Therefore

The Effects Different Types of Water Have on Plant Growth Abstract This experiment examines the rate of plant growth when watered with different solutions. Throughout the course of a nine week period‚ five lima bean seeds were watered with five different solutions to see which will most enhance the growth of plants. The five solutions consisted of distilled‚ filtered

The Effects Sodium Chloride has on pond water Introduction Ponds are depressions in the ground that fill with water from either run offs or melting snow or rain fall from many different weather changes. There are two types of ponds permanent and temporary. Ponds tend to be much smaller in size and are usually only six to ten feet in depth. This differs from a lake because the size of a lake is much larger and is much deeper. The temperature of a pond is usually the same from top to bottom and
