Prove your answer. A- When you take 700ml x1g/mlx1ml/.91g it is equal to 769ml. 769ml is greater than 750ml was maximum capacity of the bottle. When the water turn to ice its expended 19ml more what the bottle can take. For that it will burst.
The average performance of DFA large company value fund has very small difference with crsp cap decile #1. It is a little lower than S&P 500. It means the portfolio is diversified to eliminate unsystematic risk, but tracking error is also exist.The reason of the tiny difference may be timing or security selection. the tiny difference may be timing or security selection. What conclusions can you draw from all this?
One of the major sources of error in this experiment is that the volume of metal ball will rise while the surrounding water’s temperature rise. The metal ball has fixed amount of gas, so with higher volume the inner pressure of the metal ball will be lower. In order to reduce the error and improve this experiment, we can use a metal with lower coefficient of volume expansion. Objective: The objective of the second lab is to determine the relationship between the pressure and volume of gas with fixed temperature. Based on the Bayle’s Law, the pressure of the gas is inversely proportional to the volume with fixed temperature.
Although the data are slightly right skewed, because of the large sample size(n=152) our inference on the mean is valid, by the Central Limit Therom. The Box Cox plot suggests a power transformation using a power, p= -0.5 would make the data more shaped like a normal distribution. The Normal Q-Q plot shows the transformed data points lying close to the straight line and the box plot of the transformed data looks symmetric with two outliers. The numerical summary of the transformed data confirms that the transformed data are symmetric (mean=1 and median=1). A Shapiro-Wilk test on the transformed data provides no evidence against the transformed data having come fro a normal distribution (P-value=0.4286).
The oil will be in the first layer, in short, oil will float on the water. Because of the greater density of water. If I stir the mixture, the water and oil will be mixed together, but they will not
Another reason I believe that the low-density Polythene will break first is because the monomers are in straight lines and the high-density polymers overlap giving the material more strength. Conclusion: My graphs show the best estimates for all of the measurements taken disregarding anomalous results. The overall trend is that when more weight is added, the plastics stretch more (which follows Hookes Law; extension is proportional to force applied). Therefore, we can see a positive correlation. When comparing the two different materials on a graph the slope of the line gives an indication of the average (mean) extension at a given force for both the low-density Polythene and the high density Polythene.
However, boron has an electronegativity that is very similar to hydrogen, meaning there is likely very little ionic character in the hydrogen to boron bonds, and as such this Lewis structure, though it does not fulfill the octet rule, is likely the best structure possible for depicting BH3 with Lewis theory. One of the things that may account for BH3's incomplete octet is that it is commonly a transitory species, formed temporarily in reactions that involve multiple steps. Let's take a look at another incomplete octet situation dealing with boron, BF3 (Boron trifluorine). Like with BH3, the initial drawing of a Lewis structure of BF3 will form a structure where boron has only six electrons around it (Figure 6). Figure 6 If you look Figure 6, you can see that the fluorine atoms possess
The C=O stretching of the products are slightly lower than the C=O stretching signal exhibited by ethyl acetoacetate. This is because the product composes of unsaturated esters. On the other hand, ethyl acetoacetate composes of saturated ester. Finally compared to urea, the N-H stretch for the products has 2 bands and the frequencies are lower due to the presence of hydrogen bonding. f) 1H NMR Spectra Analysis g) Benefits of Solvent-Free Biginelli Reaction Firstly, there is less waste generated in the solvent-free method since solvents are considered as waste.
The negative regression coefficient is surprising – perhaps higher carat diamonds are lower in price for some reason not considered in this regression. -Is this regression coefficient significant at the alpha = .01 level? : Yes. Regression output from analysis 2: [pic] [pic] (3) Again, using only the data for diamonds with a price of $2,000 or more, the next step requires the use of dummy or indicator variables. Using the data column “certification” assign a dummy variable by grouping GIA or AGS certified together (code these as a “1”), and the remaining codes set to “0”.
In the collision theory reactions can happen when the reactant particles collide successfully but most collisions are not successful. The reason is the particles have different kinetic energy but only a small fraction of has enough energy to break bonds and have chemical change. It can be observed by changing the factors of the reactants. For example: As the temperature is increased the reaction rate will increase. When we increase the temperature of the Hydrochloric acid (HCl) the reaction will be quicker, more gas will be formed in a short amount of time.
