What is the strongest non covalent interaction? Ion-ion, dipole-dipole and ion-dipole interactions The strongest type of non-covalent interaction is between two ionic groups of opposite charge (an ion-ion or charge-charge interaction). This is called a dipole-dipole interaction. What are the four types of noncovalent interactions? There are four main types of noncovalent bonds in biological […]

What are the two properties of materials? Physical versus chemical Physical properties refer to properties that can be observed or measured without changing the composition of the material. Examples include colour, hardness and smell and freezing, melting and boiling points. Chemical properties are discovered by observing chemical reactions. What are some properties you can observe? […]

What happens when wax is heated? When we heat wax, it melts. The state of wax is solid before melting, which on heating converts to liquid wax. when heated wax melts . Only the melting point is different for dofferent and hence they melt at different temp. What happened to the molecules when heat is […]

What happens to water molecules after they have condensed to form clouds? After Water Condenses. Some of the water vapor in the atmosphere that condenses is stored in clouds. Clouds are more likely to form when the air is humid and contains more water vapor. The energy released when gaseous water vapor condenses to form […]

How is a constant volume calorimeter made? The weighed sample is placed in a crucible, which in turn is placed in the bomb. The sample is burned completely in oxygen under pressure. The sample is ignited by an iron wire ignition coil that glows when heated. The calorimeter is filled with fluid, usually water, and […]

What makes a theory a law? Scientific law vs. theory and facts. A hypothesis is a limited explanation of a phenomenon; a scientific theory is an in-depth explanation of the observed phenomenon. A law is a statement about an observed phenomenon or a unifying concept, according to Kennesaw State University. What is the difference between […]

What is the name of the compound whose formula is PCl3? Phosphorus trichloride What is the formula for phosphorus trichloride? PCl3 What is the chemical name of P4S7? Phosphorus sulfide What is the name of N2F4? Nitrogen fluoride What is C3S2? Carbon subsulfide is an inorganic chemical compound with the formula C3S2. This liquid is […]

How many electrons are in an atom of zirconium rounded to the nearest whole number? 40 electrons How many electrons are in an atom of zirconium? How many protons neutrons and electrons are in an atom of zirconium Zr with a mass number of 92? Name Zirconium Atomic Mass 91.224 atomic mass units Number of […]

Does grinding increase solubility? Crushing or grinding increases the surface area of the salt that is exposed to the molecules of water. Stirring increases the speed at which the particles of salt come in contact with the water molecules. Why does crushing a solute increase the rate of solution? Crushing it has increased the surface […]

Which statement is true of all scientific endeavors? Scientific endeavors is basically all the things that would contribute to the process of achieving a certain scientific knowledge, from the initial observation, up to the point until we can hold that certain thing as acknowledged truth. So, All scientific endeavors are supported by evidence. What is […]
