What is the formula of solubility? Solubility is measured either in grams per 100 g of solvent – g/100 g – or number of moles per 1 L of the solution. Divide the mass of the compound by the mass of the solvent and then multiply by 100 g to calculate the solubility in g/100g […]

What do scientists mean when they describe light as having a wave-particle duality quizlet? – Light is made up of electric and magnetic energy. – Light can travel through a vacuum. What do scientists mean when they describe light as having a wave-particle duality? That light is both a wave and a particle simultaneously. (Light […]

Is 42 psi too much for tires? 42 should be fine. Anything 17″ or larger with a with a 45% or less aspect ratio should use between 39-49 psi. 42 should be fine. Anything 17″ or larger with a with a 45% or less aspect ratio should use between 39-49 psi. What happens if you […]

What are the three scales used to measure temperature? Three scales are commonly used for measuring temperature. The Celsius and Fahrenheit scales are the most common. In which scale body temperature is measured? Thermometers measure temperature according to well-defined scales of measurement. The three most common temperature scales are Fahrenheit , Celsius , and Kelvin […]

Is Anammox an nitrification? Compared to conventional nitrification/denitrification in activated sludge systems, Anammox eliminates the necessity of an organic carbon source for nitrification, reduces energy demand for aeration and has a smaller production of excess sludge and lower CO2 emissions (BERTINO 2010). Why does Anammox occur? The anammox process occurs under anaerobic conditions by bacterial […]

What is the weight? The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton. What is the normal human weight? The world average […]

Why is volumetric efficiency less than 100? If the cylinder is filled with fuel/air at atmospheric pressure, then the engine is said to have 100% volumetric efficiency. However, if the cylinder is pulling in a vacuum, then the engine has less than 100% volumetric efficiency. Normally aspirated engines typically run anywhere between 80% and 100% […]

What can you say about a number that ends in 1 When you write it in binary? 1. If the last digit of a binary number is 1, the number is odd; if it’s 0, the number is even. Ex: 1101 represents an odd number (13); 10010 represents an even number (18). 2. How do […]
