Phosphate and nitrates are examples of polyatomic ions. Polyatomic ions, also known as molecular ions, are charged chemical species composed of two or more atoms covalently bonded or of a metal complex that can be considered to be acting to a single unit. Phosphates and nitrates are found in fertilizers and some detergents. When rain dissolves these materials make their way into the creeks and rivers. When the surface waters are rich with these materials, they can cause algae to grow, which completes with other organisms for light and other nutrients.
The atom X is phosphorus because it goes through many of the same things as phosphorus in a cycle does. One problem with phosphorus is that there is none of it in the atmosphere. This means that its cycle all occurs through the ground, producers, decomposers, and water. Other known things are that phosphorus is released from the weathering of rocks, it is absorbed by producers through its roots, phosphorus moves up the food chain as consumers eat the producers, and decomposers obtain phosphorus as they feed on dead remains of animals and it is released as waste. Phosphorus also gets into bodies of water when it combines with run-off water.
Next, there is mass this contains 5 sections in it these are: • challenge
Description Pennies have undergone design and composition changes over the years. Just like pennies have several versions, atoms of elements also have different versions of each other called isotopes. In this lesson, we will learn how to find the average atomic mass of the elements from its isotopes. !!! Average Atomic Mass Have you ever gone through a whole bag of multi-colored M&M’s?
Minerals 1. The minerals under the DRI for my age group would be calcium, potassium, sodium, copper ,iron, magnesium, phosphorous, selenium, and zinc. The mineral that comes below the DRI would be be potassium. However, it is not more than 80% below the DRI. However I did have a low potassium intake.
In the novel the outsiders, S.E. Hinton does a great job bringing more readers to the young adult fiction genre. It was the reason she captured the reader that keeps it popular among middle schoolers everywhere. Her revealing acts is why it is a staple for schools and readers throughout the decades. S.E. Hinton does a great job showing revealing acts through the church fire. Johnny, Ponyboy, and Dallas all risk their lives to save people, that alone shows that those three are very courageous and caring, despite being greasers.
Everyday Use and Sula are coming of age stories. They both illustrate times in people’s lives when they have to decide to how they are going to live with their past and themselves. The short story "Everyday Use", Alice Walker emphasizes the aspect of individuality. The story focuses on the lives of two sisters, Maggie and Dee.
In theory, it had a maximum yield of 100 megatons if it were to have included
after the chinese found out that gunpowder exploded they used it in a lot of fireworks until a couple hundred years later when they started using it in war. gunpowder changed war in many different ways. first of all it could be used in cannons to shoot cannonballs at the ground and make holes in the ground in these holes you could hide or use them to store things like other weapons. the smaller holes were also dangerous because people could trip over them and possibly get shot. gunpowder wasn’t just used in war people used gunpowder to mine too.
Gunpowder changed battles forever, all over the world. Without gunpowder, war wouldn’t be as deadly, and gunpowder made warfare easier to defeat the enemy (Whipps, 2009, April 6). Gunpowder was invented in 700 A.D., and Chinese alchemists used it as a weapon in 904 A.D. Gunpowder is a blend of sulfur, charcoal, and saltpeter (also known as
Chemical Warfare easily played a big role in many of our World Wars. Chemical Warfare is using chemical compounds as a weapon to use in war that involves toxic properties. It happens to be very deadly and was a way to kill an area within seconds. Since the founding of chemical warfare, many scientists like to call it a weapon of mass destruction. Many countries have decided to ban the substances all together, but because there are weaker armies those countries have chosen to keep all substances to use for fighting in battles.
In the periodic table lithium’s atomic number is 3. The atomic number describes the number of protons in the nucleus and the number of electrons in the atom when it is not ionized. (An ion is an atom where the amount of protons and electrons is not equal.) Lithium has 3 protons; therefore it must have 3 electrons when it is not ionized.
Up until now the chemical had been produced in glass bottles by reacting sulfur with potassium nitrate, or saltpeter as it was more commonly known, with steam. The potassium nitrate acted as an oxidizing agent, oxidizing
MM 3320 : Report Mass Spectrometry Submitted by Velu K R NA12B033 Introduction Mass Spectroscopy is an instrumental method for identifying the chemical constitution of a substance by means of the separation of gaseous ions according to their differing mass and charge. This method helps identify the amount and type of chemicals present
I have known SSG Seiler for many years now, so when I was asked to speak on his behalf today, I was at a loss of words as to what I could possibly say that would encompass all of my shared experiences with him. After some reflection I realized the best way to remember him is by recounting the things that I have grown to count on in having him as a friend. Generosity, SSG Seiler was always willing to fill in or take up at short notice anything that was neglected or overlooked by his peers. Reliability, he arrived at work every day 0530 ready to take on the newly presented challenges of the day. Caring, at any time during the day you go and find SSG Seiler and he would talk to you about anything, especially if it had anything to do with hockey
