Recommended: Ionic and covalent bonds

Does the type of bond determine the volatility of a substance? Explain. (3 pts) Yes, the type of bond does determine the volatility of a substance. Volatility is measure of how much a substance vaporizes into the air. Compound B, (covalent bond) was more volatile, rating a 4 on the volatility scale of 0-4, 4 being the highest and 0 being the lowest. Compound A (ionic) on the other hand, rated a 2. The reason that compound B was more volatile is because ionic bonds consist of a strong positive and a negative charge which prevent them from breaking apart, and vaporizing into. Covalent bonds are weaker because they have to share electrons between multiple atoms, and often just cloud around each other. This means that covalent bonds can be more …show more content…

The word dissolve means to mix and dissipate into a substance. In our data, compound A (ionic) rated a 3 on the scale of 0-4, 0 being not at all soluble, and 4 being completely dissolved. Compound B (covalent) rated a 0 on the same scale of solubility. This means that ionic compounds are more soluble than covalent compounds. I think that this is because of the positive and negative parts that make up an ionic bond. Since water molecules have both negative and positive parts, the atoms forming the ionic bonds would split up, and bond with other atoms. For example, if the ionic compound Sodium fluoride (Sodium+Fluorine) compound broke apart, Fluorine might bond with a hydrogen atom in the water. This is because Fluorine has 7 valence electrons and has a -1 charge and Hydrogen has 1 valence electron and a +1 charge. The two atoms combined would satisfy an octet (8 …show more content…

It also means getting brain damage.Taking this into consideration, I think that a covalent compound would be more dangerous because in general covalent compounds are more volatile. This would mean that when the covalent compound heats up, the atoms would become move around becoming agitated. The weak bonds of the covalent compound would break, and therefore make the substance even more volatile. The vapors produced would reach your nose, get inhaled and cause brain damage. Acetone for example, is a covalent compound which consists of three carbon atoms, six hydrogen atoms, and one oxygen atom all sharing electrons. Acetone is dangerous near a fire: it is extremely flammable because , its volatile vapors can “cause dry cracked skin and harm the nervous system,” according to

  • Beet Lab Report

    610 Words  | 2 Pages

    The beet Lab experiment was tested to examine bio-membranes and the amount of betacyanin extracted from the beets. The betacyanin is a reddish color because it transmits wavelengths in red color and absorbs most other colors. The membrane is composed of a phospholipid bilayer with proteins embedded in it. The phospholipid bilayer forms a barrier that is impermeable to many substances like large hydrophilic molecules. The cells of beets are red and have large vacuoles that play a big role for the reddish pigment. This experiment aimed to answer the question, “How do cell membranes work?” The hypothesis we aim to test is: Cell membranes work as a fluid mosaic bilayer of phospholipids with many embedded proteins. We predicted that the 50% Acetone will break down the most betacyanin. Our hypothesis was proven wrong by our data collected. We could test our predictions by doing the experiment multiple times and compare the

    The MSDS, or material safety data sheet, for 2-butoxyethanol outlines basic health risks that accompany it, along with basic chemical and physical properties. One of the physical properties is the fact that it is a liquid at room temperature, which means it takes the shape of its container and its molecules are not definitively packed. Chemical properties include flammability, which is whether or not it ignites easily, and toxicity, whether or not it is poisonous to humans. 2-butoxyethanol is both flammable and toxic, meaning it does ignite easily and is poisonous to humans It says that 2-butoxyethanol has a health hazard number of two and fire hazard number of two. The health hazard number means that it can cause injury upon exposure and requires rapid medical treatment. The fire hazard number means that it can ignite w...

  • Unknown Solution Lab Report

    I believe that the first unknown solution is made up of molecular compounds. This is because the solution had very little conductivity, meaning there was not an equal amount of ions broken down in the solution. The solution had no scattering, which means the molecular compounds were fully dissolved in their solvent, which was not water. When tap water was added to solution 1, the color changed from green to blue. If water was the original solvent, we would not see this color change. The absorption spectrum follows most of what the color green would absorb on its own: red, blue, and purple wavelengths. However, there was some absorption of the green wavelength. The first solution has the highest overall absorbance

  • Heart Rate Lab Report

    1142 Words  | 3 Pages

    The purpose of this experiment was to gather data on how the amount of time spent active impacts the speed of heart rate in beats per minute. The hypothesis stated that if the amount of time active is lengthened then the speed of the heart rate is expected to rise because when one is active, the cells of the body are using the oxygen quickly. The heart then needs to speed up in order to maintain homeostasis by rapidly providing oxygen to the working cells. The hypothesis is accepted because the data collected supports the initial prediction. There is a relationship between the amount of time spent active and the speed of heart rate: as the amount of time spent active rose, the data displayed that the speed that the heart was beating at had also increased. This relationship is visible in the data since the average resting heart rate was 79 beats per minutes, while the results show that the average heart rate after taking part in 30 seconds of activity had risen to 165 beats per minute, which is a significantly larger amount of beats per minute compared to the resting heart rate. Furthermore, the average heart rates after 10 and 20 seconds of activity were 124 and 152 beats per minute, and both of which are higher than the original average resting heartbeat of 79.

    Carbon monoxide is a major component in smoke from fires. It can cause a loss of mental acuity, acute nausea and severe headaches (Reinhardt 33). Death can occur at extreme levels of this intoxication and it can even cause shortness of breath and dizziness (Reinhardt 35). It may not seem like it is that bad, but one must consider that these things add up and can really affect their health and well-being. The carbon monoxide levels tend to shoot up when the wind speed goes up during daily exposure (U.S. Department of Agriculture 3). It also depends on what kind of duties you have as a firefighter; because those with the highest level of carbon monoxide in their system were a part of the direct attack and those with the least were the fire starters (U.S. Department of Agriculture 3). Carbon monoxide is a powerful poison that can kill you and it is absolut...

    Covalent and ionic are two forms of atomic bonds both of which differ in their structure and properties. Firstly, it should be made clear that an atom’s desire is to achieve stability. Most atoms by nature are not balanced electrically. They achieve balance by sharing or transferring their outermost energy level which contains electrons called valence electrons. The number of valence electrons in an atom mostly determines that atom’s or element’s properties.

  • Phase Change Lab Report

    704 Words  | 2 Pages

    Introduction: A phase change is a result from the kinetic energy (heat) either decreasing or increasing to change the state of matter (i.e. water, liquid, or gas.) Thus saying, freezing is the phase change from a liquid to a solid which results from less kinetic energy/heat. Also, melting is the phase change from a solid to a liquid which results from adding kinetic energy/heat. So, the freezing and melting point of something is the temperature at which these phase changes occur. Therefore, a phase change will occur when a vial of 10 mL of water is placed into a cup of crushed ice mixed with four spoonfuls with 5 mL of sodium chloride for 30 minutes. If 10 mL of water is placed in an ice bath, it will then freeze at 5 degrees Celsius because the kinetic energy will leave quicker with the ice involved. The purpose of this lab is to observe what temperature the water must be to undergo a phase change.
