    At first glance, all the substances may have been considered to be similar, as they are all white substances that are generally fine powder or small crystals. However, the lab revealed substances C: citric acid, D: sucrose, and H: benzoic acid to be covalent compounds, while the remaining substances to be all ionic. The previously stated covalent compounds all were found to have low relative melting points when heating them on a hot plate, but they had mixed results to their solubilities: citric acid and sucrose were found to be soluble in water, while benzoic acid was not soluble in water. The situation was reversed when using ethanol: citric acid dissolved slightly while sucrose did not at all, and benzoic acid was able to dissolve. The differences are caused due to ethanol being less polar than water. Based on the results with water, sucrose and citric acid are likely polar molecules because they were able to dissolve, while benzoic acid is likely nonpolar due to it not…

    Chemistry, oh chemistry! Chemistry is an interstmig subject. Withourt it we would not know many of the thigns we do today. However, with chemistry comes a lot of studying and hard work. There are three bonds in chemistry ionic, covalent, and hydrogen. Do not ask me why they named them this because I am unble to tell you this. However I can tell you that SCl2 is an ionic bond and NaCl is a covalent bond. Well, that is that the atoms in them form those types of bonds. Hard to belive I know, but…

    acid and a base react to form an ionic compound (a salt) and water; the resulting pH is closer to 7. The general chemical equation for a neutralization reaction is: Acid + Base Water + Ionic Compound This can also be considered as a double displacement reaction. However, since the reacts are an acid (carbonic acid) and a base (sodium hydroxide) and the products are a salt (sodium carbonate) and water (H2O), it is more specifically a neutralization reaction. c) If you were able to take the…

    Introduction In order to create a compound, there must be two or more atoms that bind together. These atoms may be made up of different elements, or some may be the same. There are two main ways that atoms bind together- covalently and ionically. In a covalent bond, two non-metals of similar electro negativities come together to share electrons with each other. These electrons come from the outer-valence shells, and are shared in a way so that both electrons can have satisfactory shells,…

    Salts and molecules have different properties because salts are ionic compounds and molecules are covalent compounds. Justification: Salt is an ionic compound. An ionic compound is formed by ionic bonding between ions of opposite charge. Sodium Chloride and Potassium Bromide are both salts that have an ionic compound. Both elements have the properties of salts which include soluble in water, conductive, and a relatively high melting point. Molecules and Sugar molecules are covalent…

    to attract electrons to form bonds. Now atoms like to fulfil the octet rule of having a perfect 8 outer shell causing it to be stable. Now unfortunately not all elements have a full outer shell now elements on the left side of the periodic table contain less than half of electrons the required energy to gain electrons is much higher than comparison to trying the energy to lose an electron. So the elements on the left side when they form bonds they actually lose electrons. Now on the right side…

    In particular, B, G, and E of hexagonal structure are expressed as follows [34]: where B, G, and E are bulk, shear, and Young’s modulus, respectively. The resultant elastic constants, bulk, shear, and Young’s modulus are summarized in Table 2. Here, it can be seen that the B, G, and E are increasing with increasing amount of Si on the A site. This could be attributed to the charge density shown in Table 1. In particular, the substitution of Al with Si increases the total charge density of the A…

    with the fact that it does not react with NaOH, NaCl, or AgNO3, all ionic substances. The red dye does not react with NaOH since there was no color change when added, and the conductivity simple rose as the NaOH was added, due to the fact the excess ions were being added to the solution and not reaction at all. There was no color change when NaCl or AgNO3 was added to red dye 1,…

    of the solute. The colligative properties studied in this current chapter of chemistry are: vapor pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure. The van’t Hoff factor for a solute is equivalent to the number of particles, in moles, will break apart in the solvent. When an electrolyte is dissolved in water, the compound separates into ions. The number of moles of the total ions resulted after dissolution is the van’t Hoff factor for that particular…
