Interactions Of Group 1 And 2 Elements And Their Compounds Lab Report

When combined Sodium Bicarbonate and Hydrochloric Acid, Carbon Dioxide is produced. The two chemicals do not undergo a change in color but a chemical change when CO2 is produced.

the bubbles during the reaction. Starch acts to trap these bubbles and this creates a

Solub. Or Reaction w/ hot H20: no change observed from the cool water and is soluble

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.

From highest to lowest energy emitted, the metal ions are as follows: potassium ions, copper ions, barium ions, sodium ions, calcium ions, strontium ions, and lithium ions.

B. Claim: As we go from methanol  ethanol  1-propanol  1-butanol the dispersion forces increase.

The City of Mounds View, located in the northwest corner of Ramsey County, Minnesota, contains a residential population of over 12,000 and over 150 businesses. The city is situated at the connection of Interstate 35W and State Hwy 10, and is conveniently ten miles from Minneapolis and St. Paul. Mounds View is renowned for its large, wooded residential lots and wide housing variations. The city has a total area of 4.12 square miles, of which 4.03 square miles is land and 0.09 square miles is water.

All elements had a reaction but potassium had a greater more rapid reaction than the others. This indicates that elements that are lower in the periodic group will have a faster and greater reaction. This is due to its decreased electronegativity where it is easier for that element to lose its valence electron and hence having a faster and greater reaction, as the last elements in group 1 have a greater atomic radius than the beginning elements of group 1. In all elements there was a reaction which created hydrogen gas and made a solution that was alkaline. All the elements dissolved and turned the water purple; this indicates that all the elements tested are base, Alkali metals elements.

1 tsp. water- (compound) H2O. H20 is the basic chemical formula for water, which is Hydrogen2 + Oxygen and that means that there is 2 Hydrogen Particles with 1 oxygen particle. Water makes it easier for the bath bomb to dissolve in water. The water in also there to mix all the ingredients together, to bring them together.

When mixed with hydrochloric acid (appendix 4), they react violently, hence why only a small portion was allowed for this experiment. This supports the hypothesis, that is, it was predicted that such a reaction would occur as these metals are highly reactive, hence why the hydrogen gas produced was clearly visible (appendix 5). Tin is less reactive, however, according to the Metal Reactivity Series, reacts with acids at an extremely slow rate. This was evident in the experiment; however, more of a reaction would have occurred if the time frame was expanded. The metal was only left in the acid for five minutes; therefore, it had no reaction but could of, had it been left a while longer. Magnesium and Calcium are both alkaline earth metals which means that they all have an oxidation number of ‘+2’, making them highly reactive. Calcium is more reactive than Magnesium even though it is located below it on the periodic table (appendix 6) because its electron configuration is ‘2,8,8,2’ while Magnesium’s is ‘2,8,2’. This means that Calcium has more shells which, therefore, means that there is less of an attraction to the nucleus. This makes it easier for Calcium to lose electrons and react more so than Magnesium. According to the Metal Reactivity Series, in order from the most reactive to the least reactive, tin is located at around the middle of the

Introduction: Substances can be created and can go through a chemical change. When a substance is produced this is a reaction or chemical change this is also called the product. If a substance is the reason why the experiment this is called a reactant. Whether it is a product or a reactant it depends on what happens in the chemical reaction. There is many types of chemical reactions.

The main purpose of this experiment was to show that single displacement reactions between metals according to their reactivity, with more reactive elements having the power to displace less reactive elements and take their place in a chemical compound (Beran, 2014). This was supported by the results of the experiment, where solid metals were combined with aqueous solutions that contained another element, and reactions only took place when the solid metal was more reactive than the other element in the compound. Only three attempted trials resulted in a failure to produce a reaction, namely the combinations of copper with hydrochloric acid, and copper with nickel sulfate. The outcomes of these trials are justifiably reasonable because copper is ranked lower in the

Lithium and Sodium are more reactive than magnesium. This because lithium and sodium both have a lower valence than magnesium making it more reactive. Lithium and sodium are both in group one where as magnesium is in group 2 meaning that anything in group one

From the observations of the reactions of alkali metals, it is conspicuous potassium was the most reactive due to the fact the reaction between water and potassium was immensely more vigorous the other alkali metals. Additionally, there was a burst of sparks and flames in the potassium reaction also a great amount of bubbling and gas formed, greater than the other reactions. The reaction partaken between sodium and water was seemingly not as reactive as potassium, from the experiment it can be inferred that only sparks and some formation of gas and bubbling were observed. Moreover, lithium was the least reactive, there were no sparks or flames evident, rather only a small amount of bubbling and formation of gas occurred.

The contents of the beakers are mixed, and the reaction was timed until the solution turns blue.
