What reaction occurs when a current is applied to two electrodes immersed in pure water? Water can be decomposed by passing an electric current through it. When this happens, the electrons from the electric current cause an oxidation-reduction reaction. At one electrode, called the cathode, electrons pass into the solution and cause a reduction. What […]

How do you use a bimetallic thermometer? Bimetallic Stemmed Thermometers: Stick the sensing tip of the thermometer into the cup being sure not to touch the sides or bottom of the cup. Wait four or five minutes or until the needle is steady. If the needle does not read 32 degrees F (0 degrees C) […]

Is adiabatic process slow or fast? An adiabatic quasistatic process is isentropic (by the definition of entropy), and we often use the two words interchangeably (because we usually consider quasistatic processes). Chemists may tell you that an adiabatic process is fast. Physicists will usually describe it as slow. Is adiabatic process reversible? It is an […]

Why is the biuret test specific for proteins? The biuret test, also known as Piotrowski’s test, is a chemical test used for detecting the presence of peptide bonds. The biuret reaction can be used to assess the concentration of proteins because peptide bonds occur with the same frequency per amino acid in the peptide. Do […]

What are the 3 main types of volcanoes? Individual volcanoes vary in the volcanic materials they produce, and this affects the size, shape, and structure of the volcano. There are three types of volcanoes: cinder cones (also called spatter cones), composite volcanoes (also called stratovolcanoes), and shield volcanoes. What are the 3 main types of […]

What is fossil fuel How is it formed what kind of source of energy is it? Fossil fuel is a general term for buried combustible geologic deposits of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure […]

What happens to molarity when temperature increases? Molarity is no moles in 1 litre solvent. As temperature increases, volume also increases, which means that it will decrease the number of moles per litre. So, molarity decreases as the temperature increases. Does Molality change with increase in temperature? In the case of molality, moles are proportional […]

How do you write an error in a lab report? Error analysis should include a calculation of how much the results vary from expectations. This can be done by calculating the percent error observed in the experiment. The error analysis should then mention sources of error that explain why your results and your expectations differ. […]

What are the 5 phases of the design process? The design thinking process is broken up into five specific design thinking stages: empathy, definition, ideation, prototyping, and testing. What are the 6 steps to the design process? THE DESIGN PROCESS CONSISTS OF 6 STEPS: Define the Problem. You can’t find a solution until you have […]

What does a societal law mean? The term has both been used to mean fields of law that fall between “core” private and public subjects, such as corporate law, competition law, labour law and social security, or as a unified concept for the whole of the law based on associations. … Why can’t a theory […]
