Compound Reactions Write-Up

What is the appearance of reactant, Evidence of chemical reaction, and properties of a product?

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.

Purpose: The purpose of this lab is to investigate the relationship between the relative reactivity of several metal elements and where the elements are found on the periodic table. There are many factors pertaining to the order in which the elements are laid out and in this lab, determining the reactivity levels of certain metals will lead to patterns. The placement of elements in groups is usually related to the reactivity level. The purpose of this lab is to examine these levels and figure out if there is an increasing reactivity pattern, decreasing, or if there is not one at all.

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

A chemical reaction is when substances (reactants) change into other substances (products). The five general types of chemical reactions are synthesis (also known as direct combination), decomposition, single replacement (also known as single displacement), double replacement (also known as double displacement), and combustion. In this lab, the five general types of chemical reactions were conducted and observations were taken before, during, and after the reaction. Then the reactants and observations were used to determine the products to form a balanced chemical equation. The purpose of this lab was to learn and answer the question: How can observations be used to determine the identity of substances produced in a chemical reaction?

The objective of this experiment will be to combine various substances, liquids and metals, and to observe their behavior when they are combined. The types of reactions observed shall determine the nature of these reactions: physical or chemical.

This is a simple equation that doesn’t properly prove the reaction. It is very complex and starts with this:

| Combustion product reacted by becoming cold, dissolving, and no gas formation with an end product is clear colorless solution.

Write a balanced chemical equation for each reaction #1-8. Classify each reaction using the information provided in the

The first reaction involves pyrite rock reacting with oxygen (air) and water to produce dissolved ferrous iron, sulfate, and acidity. The second reaction oxidizes the dissolved ferrous iron in acidic conditions and produces ferric iron and water. The third reaction involves the hydrolysis of the ferric iron to form ferric hydroxide and more acid. The ferric hydroxide is the orangey-red colored solid you see in the water (Juniata College).

Comparison of the Behaviour of Halides Purpose: to compare the properties of halides and relate them to the position of halogens in the periodic table. To use these properties to identify an unknown halide. Hypothesis: The halogens that are further down the group are more reactive than those that are further up. Also, Unknown substance C will be sodium iodide.

This paper is about chemical reactions and chemical reaction types. All the data gathered was from conducting multiple experiments. Each experiment was performed carefully and analyzed to obtain the necessary information for the paper. That information included the four signs of a chemical change, the rnx type, and more.

The reaction between sodium sulfate (Na2SO4) and barium chloride (BaCl2) created a white precipitate. This reaction possibly

Part A.1. Sodium metal is also readily oxidized by oxygen. If the product of the reaction were dissolved in water, what would be the color of the litmus for a litmus test? Explain. What is the product?

As you go down the periodic table you can clearly see that the reaction decreases and this can be because the metals don’t really react as they should, this can be because when they get into contact with any of the substances they don’t really have a chemical reaction to them, this can be because they don’t react as they should when placed in acid. Aluminium –Copper there wasn’t really a reaction and this is because these metals didn’t really have any acid base substance in them. The other thing is that From this you can see that potassium reacted with everything and every substance that it was mixed to clearly showed a major reaction, this can be because of where it is placed in the periodic table, the fact that this is the last one from group 1 means that it is a metal that reacts really quickly because of the ion bonds it has on its outer layers, lithium is found at the top of the group 1 metals and this one clearly shows that it doesn’t really react that quickly and this can be because it isn’t a strong metal like potassium, the other thing you can see from lithium is that on all of them you can see there was a slow reaction this can be because of the ion bonds it may have and because this is a small metal it may not be stronger like the others. So clearly from the group 1 metals
