Why does higher electronegativity increase acidity? Electron drift occurs when electrons are attracted by highly electronegative atoms away from bonded OH groups. The electron density between the oxygen and hydrogen atom is distorted by the electrons’s attraction to the electronegative atom, and this further polarizes and weakens the O-H bond, making a stronger acid. How […]

How do you calculate power? Power is a measure of the amount of work that can be done in a given amount of time. Power equals work (J) divided by time (s). The SI unit for power is the watt (W), which equals 1 joule of work per second (J/s). Power may be measured in […]

What does R stand for in free body diagram? Contact force between table How do I fix FBD problems? Follow this seven-step method to solve force problems: Draw each of the objects you’re interested in. Identify the forces acting on each object. Draw a free-body diagram for each object. Choose a coordinate system for each […]

Is Fossil fuel a biomass? Biomass and biofuels made from biomass are alternative energy sources to fossil fuels—coal, petroleum, and natural gas. Burning either fossil fuels or biomass releases carbon dioxide (CO2), a greenhouse gas. Which is cheaper biomass or fossil fuels? The International Renewable Energy Agency has released a new report that determined many […]

How many galaxies are blue shifted? 100 How do you calculate wavelength difference? How to calculate wavelength Determine the frequency of the wave. For example, f = 10 MHz . Choose the velocity of the wave. Substitute these values into the wavelength equation λ = v/f . Calculate the result. You can also use this […]

What is the period number? If you are given with the atomic number of an element you can find it’s period number and group number. The period number is related to the number of electron occupied shells in the element and the period number is linked to its valence electrons. Which period can you find […]

How do you classify strong electrolytes? Strong electrolytes fall into three categories: strong acids, strong bases, and salts. (Salts are sometimes also called ionic compounds, but really strong bases are ionic compounds as well.) The weak electrolytes include weak acids and weak bases. What are strong and weak electrolytes give examples? For example: HCl, H2SO4, […]

What is Latitude define with diagram? Latitude is an angle (defined below) which ranges from 0° at the Equator to 90° (North or South) at the poles. Lines of constant latitude, or parallels, run east–west as circles parallel to the equator. Latitude is used together with longitude to specify the precise location of features on […]

What will happen when the condensate reaches the thermometer bulb? Distillation should be done steadily and at such a rate that the thermometer bulb always carries a drop of condensate and is bathed in a flow of vapor. However, sugar molecules do not leave the solution, and the drop clinging to the thermometer bulb is […]

Is Carborundum man made? 11/10/2015. ATTRIBUTES: Carborundum is a man made crystal also known as Silicon Carbide. In 1891, Edward Goodrich Acheson discovered Carborundum in an attempt to create diamond using electricity. Carborundum energetically purifies the mind, body and spirit while encouraging intuition and discernment. Is Carborundum a diamond? Carborundum, trademark for silicon carbide, an […]
