In this experiment, the freezing point for the solvent biphenyl will be determined theoretically and experimentally, as well as the verification of the freezing point depression equation for a solvent/solute mixture. Represented by the equation kf=RTf2MΔHf , the freezing point depression will be constant for a solvent despite whether a solute is involved in the experiment. The freezing point equation can later be used to calculate the temperature the solvent freezes represented by the equation, ΔTf=-ikfnsolutemsolvent . The freezing point of the solvent containing a nonvolatile electrolyte will be equal to the addition of the freezing point depression to temperature of the pure solvent and will always be lower than the freezing point of the pure solution. Because the freezing point depression is a colligative property, the higher the concentration of
According to the Le Chatelier’s principle, if a chemical system at equilibrium experiences a change in concentration, temperature, volume, or partial pressure, then the equilibrium shifts to counteract the imposed change and a new equilibrium is established. In this experiment, the effect of temperature change on the equilibrium position of the above chemical equation by comparing the state of the reacting mixture when it is in high temperature and low temperature. As the ∆H>0, the increase of temperature would expected to shift the equilibrium to the right. Procedure: 1. Using a measuring cylinder, pour 20 cm3 of 0.01M saturated cobalt (II) chloride solution at 0℃ and pour about 100 cm3 of deionized water to a 250 cm3 beaker.
When and how do we use them? “Logic allows us to analyze a piece of reasoning, and determine whether it is correct or not. To use the technical terms, we determine whether the reasoning is valid or invalid”. We use logical arguments to support our beliefs and to persuade others to understand our belief. Logical arguments are a way for us to analyze information and decide whether it is valid or invalid.
Projectile Motion Exercise 3’s Results The purpose of this exercise was to determine the relationship between the predicted and measured ranges of the projectile when it is fired at an arbitrary angle with respect to the horizontal. Throughout all the processes of observing, calculating and measuring, the experiment’s result is consistent with the expectation that Equation (3) can be used to find the range as long as the initial speed does not change.

An ordinal scale describes a whole preorder of things; the scale importance is to have a total order. Ranked preferences only tell what one preference is over another, not how much more is desired. Quantitative traits are all calculable with interval scales, as some variation with the levels of an trait will be able to be multiplied by a real number to surpass or equivalent some other variation. A very well-known illustration of interval scale capacity is temperature with the Celsius scale. The thermometer signifies equal amounts of mercury between each interval on the scale.
And only other potential result would be that changeable variable A and B are not related. In point of fact, this hypothesis that we support the alternative hypothesis, and we call the hypothesis that describes the other possible result that left which is the null hypothesis. Sometimes we register some symbols like HA or H1 to represent the alternative hypothesis or our guess, and H0 to represent the null case. Alternative Hypothesis is e a hypothesis that usually means in opposition to the null hypothesis. There are two types of
To do this, first, we must find the slope for the given test points, (110,0) and (0, 330). The equation for slope is =y2-y1x2-x1 , or (m = rise/run), so … m = 330−(0)/0−(110) Multiply by -1 to get rid of parentheses m = −330/110 Cancel out the common factor of 110, and simplify m = -3 Next, find the equation of the line using y=mx+b y = (−3)⋅x+b Input the points of x and y (0) = (−3)⋅(110)+b Multiply 0 = b−330 Solve for b b = 330 So, the equation of the line is … y = −3x+330 Next, multiply by -1 to get the inequality 3x+y ≤ 330 Final answer The graph will have a solid line instead of a dashed line. b.) Will the truck hold 71 refrigerators and 118 TVs? First, we need to make x = 71 and y = 118; this is our test point – (71, 118) 3(71)+118 ≤ 330 Input the values, then simplify 331
