Difference Between Homogeneous And Heterogeneous Mixture

4.) I noticed that there is a relationship between the ionic radius and the atomic number of the representative elements in Group 1A. The higher the atomic number, the bigger the ionic radius is. So, while hydrogen has an atomic number of 1 and Francium has an atomic number of 87, it is safe to assume that FR has a higher ionic radius. This is true; the ionic radius for Hydrogen is 0.012, and for Francium, it is 0.194.

Taco and Burrito are both Mexican food, but they are different in ingredients and history. One difference between Taco and Burrito is the history of both foods. Taco are the ancient food which have been eaten since the beginning of American. In contrast, Burrito was invented by an merchant who deside to serve rice and bean without using the plate in 20th century, so Taco have origin older that Burrito. Another difference on Taco and Burrito is wrapping ingredient.

The water in salty water (only the water) is the __________. a. Solvent c. Solute b. Solution d. Concentrate 3. A mixture of salt and water is knows as: a. Solvent c. Solute b. Solution d. Concentrate 4. What do you call a solution that contains more solute dissolved in it that it can hold at a specific temperature: a. A solution c.

8) Explain how each experiment type (question 7) differs from the

Within the chemical reaction are two different parts, the reactant and product. The reactant, “an initial substance in a chemical reaction” was the alka-seltzer tablets, before they were placed into the water. For instance, when the untouched alka-seltzer was then placed into the water, it formed the product, “the final substance in the chemical reaction” (Tro, 2018). Now, by looking at how the water, or the solvent, dissolved the alka-seltzer tablet, it then created a solute, or a “dissolved substance” (Shuster, 2014). Another example, on a personal level, of a chemical reaction was, whenever I had a sore throat, as a child, my

- ​A hydrate is a salt that contains water as a part of its crystal structure. The hydrate used in this lab was Copper (ll) Sulfate Pentahydrate. To heat the hydrate in this lab a crucible is needed. A crucible is a heat resistant container used to heat things to high temperatures. In this lab a mole was used to determine the measurements of all substances.

For example, an experiment similar to this one could be how pressure could affect the time it takes for an Alka-Seltzer tablet to dissolve. Using A flask and rubber stoppers, you can compare the amount of time it takes for and Alka-Seltzer tablet to dissolve in regular room temperature water and room temperature water in a flak but with a rubber stopper stopping the air flow into the flask. This is related to the experiment performed above because the increase in pressure from the rubber stopper stopping the air flow in and out of the flask may affect the time it would take for the Alka-Seltzer tablet to dissolve. Another example of an experiment related to the one performed above is how the amount of water used to dissolve an Alka-Seltzer tablet effects the time it takes for one to dissolve. This also relates to the experiment performed above because it also affects how fast the rate of reaction is.

Properties of Ionic and Covalent Substances Lab Report Introduction The purpose of this lab was to determine which of the following substances: wax, sugar, and salt, are an ionic compound and which are a covalent compound. In order to accurately digest the experiments results, research of definitions of each relating led to the following information: ionic compounds are positive and negatively charged ions that experience attraction to each other and pull together in a cluster of ionic bonds; they are the strongest compound, are separated in high temperatures, and can be separated by polar water molecules. A covalent compound forms when two or more nonmetal atoms share valence electrons; covalent compounds are also

This can also happen when a rich and powerful individual buy over a several different media companies of the different purposes.

Dissolving is the process in which a solvent and a solute interact with each other and form a solution. Melting is a physical, or state, change of a solid to a liquid. Based on the provided information if a substance requires a high temperature to melt and dissolves in water, then it is an ionic compound; and if a substance requires a low temperature to melt and does not dissolve in water, then it is a covalent compound. I predict that salt will be an ionic compound, since it is soluble in water, and sugar and wax will be covalent compounds because they

There are three major components of water potential and one of them is solute or osmotic potential (the amount by which water potential is reduced by the presence of solute

6.1 Marketing Mix Marketing mix is a set of controllable marketing tactics used by business to promote their product and achieve its marketing objectives. (L. Lake, 15 June 2017) Marketing mix is also called the 4Ps which consist of Promotion, Place, Product and Price. (M. J. Baker, 2001, p.54) 6.1.1 Product

This element of the marketing mix defines the approaches used to communicate with the customers. McDonald’s uses the following tactics in its promotional mix: • Advertising • Sales promotions • Public relations • Direct selling

Solubility of a Salt Introduction: The solubility of a pure substance in a particular solvent is the quantity of that substance that will dissolve in a given amount of a solvent. Solubility varies with the temperature of the solvent. Thus, solubility must be expressed as quantity of solute per quantity of solvent at a specific temperature. For most ionic solids, especially salts, and water, solubility varies directly with the temperature.

INTRODUCTION Water is a transparent and nearly colorless chemical substance that is the main constituent of Earth 's streams, lakes, and oceans, and the fluids of most living organisms. Water plays an important role in the world economy. Approximately 70% of the freshwater used by humans goes to agriculture. Fishing in salt and fresh water bodies is a major source of food for many parts of the world.
