Ammonium nitrate (NH4NO3), is classified as a salt. The salt family of chemicals contains ions, which are particles with electrical charges. Due to the fact that opposite polarity ions attract each other, they form a solid crystal that is called salt. This when seen by the naked eye seem like a simple reaction. Bu, in reality this occurs in two different steps and each step a change of energy takes place.

The four main types of crystalline solids are Ionic crystals, molecular crystals, covalent network crystals and metallic crystals. The type of a crystalline solid can be determined by testing its properties such as hardness, melting point,

in which n is a large number of moles. A chain reaction is a series of smaller reactions in which the previous reaction forms a reagent for the next reaction. The synthesis of hydrogen bromide is a good example:

Reactants collide with each other so new bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make new products

HCl, it is strong acid and when blended with ammonia, it produces a dense insoluble chloride fog.

5. Who was Sir William Crookes and what did he contribute to the urgency of producing ammonia, NH3 from nitrogen in the air?

Both experiments were able to determine the yield of hydrogen gas by testing the effect of limiting reactants, balanced equations, stoichiometry, mole ratios and molar masses. Balanced equations are equations that have a balanced number of moles of each element on both sides of the equation. Molar mass is the sum of the atomic masses of all elements combined in a chemical substance. Mole rations can be determined using the coefficients of the reactants and products in the balanced equation. Mole ratios can be used to relate moles of product formed from a certain number of moles of a reactant. Stoichiometry is the method of using the relationship between two or more substances in a chemical reaction. The limiting reactant of a chemical reaction is the reactant that is used up first in the reaction and limits how much of the product can be formed. In experiment 2-1, a company wanted to know if magnesium or aluminum would be practical to use as an alternative to zinc to produce a given volume of hydrogen gas. In experiment 2-2, the company wants to know how to optimize the production of hydrogen gas and whether hydrochloric or sulfuric acids are reasonable alternatives for gas production. The The reactions performed in experiment 2-1

In final analysis, the electronegativity and density periodic trends trends are fairly consistent. Electronegativity decreases when going down groups, while density increases. However, the outliers of these trends are the noble gases, because of their stable, unreactive properties. In addition to helping students learn about periodic trends, it also demonstrated to students how these trends were of great use for previous scientists when they worked together to discover new elements that were missing on the periodic

This report discusses how varying the mole ratio of the reactants affects the amount of the product that is produced and the amount of the reactants that remain at the end of the chemical reaction. We know that you can’t simply add another atom of nitrogen and take an atom of hydrogen away from ammonia because it would change to another substance. We also know that in a chemical reaction atoms cannot be created or destroyed but can make a new substance. A guiding question was made so they can figure out how to solve/find out what is going on. The atomic theory is connected to this lab because that the atoms in the lab cannot be created of destroyed during a chemical reaction. Meaning that each side the of the equation must include the same number of each type of atom. The relationship between the amounts of any two compounds, in moles, that are involved in a chemical reaction. In this lab we are showing how different ratios of moles of sodium bicarbonate and acetic acid and how the different moles leave and percentage out of the product but still remains in the lab. How this lab works we will combine sodium bicarbonate and acetic acid and we are see the amount of CO2 leftover after the reaction happens. Knowing this.

Refers to reducing the usage of water and recycling of waste water for different purposes such as cleaning, manufacturing, and agricultural irrigation.

The goal of this source is to inform others how ammonia fits into the chemistry as well as hydrogen peroxide.

Bismuth, the eighty third element on the periodic table, is a gray, negligibly radioactive metal that is slightly less dense than silver. You’ve probably seen it, sitting idly inside small bins in museum gift shops, or hanging on earrings, necklaces, or bracelets, or even in a brand of over the counter gastrointestinal aids. In most of these contexts, it takes the form of intricate geometric crystals, in “stairstep” patterns of inlaid

Our rivers are running dry faster than we expected. As we look for a solution to the scarcity of water, we are relying on the most abundant resource that is available on Earth — the ocean. To make the salty sea waters usable, scientists have developed desalination plants; a method that uses reverse osmosis and is already being implemented in places like California. However, as with any possible solution, the desalination process has its downfalls. Critics of the desalination project argue that it is more expensive than other potential methods and that the amount of energy required will only aid climate change. Those who support this method would argue that although it is currently expensive, new, cheaper filters will be developed in the

The filters are made out of polyamide a cheap but not durable filter. Polyamide is and affordable filter but it wares out quickly, along with it easily breaking down and it degrades when chemicals such as chlorine which has to be removed from the water before filtering and then added back in again. This make for an extra process which leads to greater cost.

The cells are placed into a flask and are forced through a nozzle so small that they must pass through one by one. In the nozzle, the cells are vibrated at different frequencies to produce drops (3). The drops of cells are then scanned by a laser that is used to count and measure each cell. Separating populations of cells involves attaching antibody linked fluorescent dye to certain cells of interest (3). The information that is gathered from the sorting and measuring of the cells is evaluated by a computer. The final steps for the FACS include applying an electrical charge to the drops of cells (3). Before the drop of cell forms at the end of the nozzle, a charge is applied to the stream that will determine where the drop will go (3). Based on the charge, the drip is either moved left or right with electrodes or placed in to designated final tubes. Quantifying the FACS information involves displaying the information so we know how many cells of each color and charge were
