How do you know if a gas is produced in a chemical reaction? Signs of a Reaction – Gas Formation The formation of a gas is the third sign that a reaction may have occurred. The formation of bubbles when two liquids are mixed usually indicates that a gas has formed. A gas can also […]

What are two characteristics of a compound? Components in a compound are present in a definite proportion. It has a homogeneous composition. Particles in a compound are of one kind. A compound is made up of one or more atoms of the same or different elements. In a compound the elements are present in a […]

How many PSI is a brake line? Metal brake lines must withstand 5000 psi tests, and most burst around 15,000 psi. Typical full-lock operating pressures on conventional OEM-style automotive hydraulic-brake systems are 900–1,000 psi (69 bar) with manual brakes and 1,400-plus psi (96 bar)with power-assisted brakes. Is it illegal to use compression fittings on brake […]

Does a 4 stroke engine need mixed fuel? 4 cycle engines do not need oil mixed with the gas to provide lubrication, since it has oil in the crankcase. Two cycle engines have to have oil mixed in the gas to provide the lubrication needed, since there is no oil in the sump. Is 4-cycle […]

Which is better Frye or Daubert? Under Frye, the scientific community is essentially the gatekeeper determining evidence admissibility. Using the strict standard, if the scientific community finds a method or theory acceptable, the court must admit the evidence. While Frye offers a bright line rule, Daubert provides courts with flexibility. What is the main difference […]

How many jelly beans are in a 2 pound bag? 49 How many jellybeans can fit in a Mason jar? Ball 16 oz Pint Mason Jar outer dimensions are 5.2 height by 3.2 diameter – which could hold approximately 390 jelly beans. Ball 32 oz Quart Mason Jar outer dimensions are 6.9 height by 3.9 […]

What is the L quantum number? The angular quantum number (l) describes the shape of the orbital. Orbitals have shapes that are best described as spherical (l = 0), polar (l = 1), or cloverleaf (l = 2). They can even take on more complex shapes as the value of the angular quantum number becomes […]

Which of the following is a postulate of the kinetic molecular theory of gases? As applied to gases, the kinetic molecular theory has the following postulates: Gases are composed of very tiny particles (molecules). The actual volume of these molecules is so small as to be negligible compared with the total volume of the gas […]

Is the tail light the same as the blinker? In many newer cars there is one light bulb per tail light. There are two filaments in each light bulb. One is for your brake light and one is for your turn signal. So when you’re stopped with your turn signal on one filament stays on […]

What is range of normal distribution? The area under each curve is one but the scaling of the X axis is different. Note, however, that the areas to the left of the dashed line are the same. The BMI distribution ranges from 11 to 47, while the standardized normal distribution, Z, ranges from -3 to […]
