Why do transition metals have 2 valence electrons? It is due to the fact that valence is the electrons in the outermost shell and because the s shell fills up before the d shell of a preceding energy level they have 2 electrons in their outermost she’ll. How do you know the number of valence […]

What is the importance of dimensional analysis?
What is the importance of dimensional analysis? Dimensional analysis can be used as a tool to construct equations that relate non-associated physico-chemical properties. The equations may reveal hitherto unknown or overlooked properties of matter, in the form of left-over dimensions — dimensional adjusters — that can then be assigned physical significance. What are the applications […]

What does an open feedwater heater do?
What does an open feedwater heater do? An open feedwater heater is basically a mixing chamber, where the steam extracted from the turbine mixes with the water exiting the pump. In an ideal condition, the water leaves the heater as a saturated liquid at the heater pressure. What is the major purpose of using feedwater […]
How do you calculate the compression ratio of a diesel engine?
How do you calculate the compression ratio of a diesel engine? Plug your numbers into the formula CR = (Vsw + Vcl) / Vcl. Now that you know the swept volume and clearance volume, simply insert those numbers into the formula and solve it. Add the swept volume and cylinder volume together first. Then, divide […]
What is used to connect the external devices and power supply to a computer?
What is used to connect the external devices and power supply to a computer? A port is a connection interface between the computer and other • computers or peripheral devices. It provides a signal transfer between devices. The power supply unit in a computer converts the power from the wall outlet (usually A/c) to the […]

Why should a speaker learn about his or her audience?
Why should a speaker learn about his or her audience? Audience analysis involves identifying the audience and adapting a speech to their interests, level of understanding, attitudes, and beliefs. Taking an audience-centered approach is important because a speaker’s effectiveness will be improved if the presentation is created and delivered in an appropriate manner. Why should […]
What converts analog signals to digital signals?
What converts analog signals to digital signals? ADCs follow a sequence when converting analog signals to digital. They first sample the signal, then quantify it to determine the resolution of the signal, and finally set binary values and send it to the system to read the digital signal. Two important aspects of the ADC are […]
