According to the cointegration analysis established in the mid-80s‚ the non-stationarity of the underlying time series does not always imply the non-stationarity of the linear combinations of these series. Hence‚ it is a prerequisite to ensure that all variables are integrated of order one in levels before employing the panel cointegration tests. Table 3 presents the results performed by Im‚ Pesaran and Shin unit root test of all variables for the four panels of economies tested in both levels

In the experiment‚ as the size of the cube decreased‚ the absorption rate increased‚ showing that the smaller cells absorbed more sodium hydroxide than bigger cells. The smaller cells were able to absorb more sodium hydroxide as they have a bigger surface area to volume ratio causing them to act more efficiently than the bigger cells. The smallest cell had a ratio of 1:12 while the biggest cell had a ratio of 1:2‚ leaving a gap of 5:12 causing the bigger cell to act less efficient in absorbing the

Title: To Investigate the Effect of Concentration on the Rates of Diffusion. What is the relationship between concentration of hydrochloric acid and the rate of diffusion? Abstract The research question that this report is going to discuss is “What is the relationship between concentration of hydrochloric acid (HCl) and the rate of diffusion?” My hypothesis for this research question is that change in rate of diffusion will be observed when the agar

investigate how does the concentration of Hydrochloric acid affect the rate of reaction? Outline I aim to discover how different concentrations of Hydrochloric acid influence the rates of reaction. In order to carry out this investigation I have decided to use marble chips‚ which I will vary the sizes as powder‚ small chips and large chips. I will also be changing the concentration‚ the different concentrations are as follows 0.2m‚ 0.5m‚ 1m‚ 1.5‚ 2m. I have chosen these concentrations as they have a good

Testing the effect of concentration on rate of reaction Plan: We are investigating the effect of nitric acid on calcium carbonate. We are doing this experiment‚ as we would like to understand the effect that acid rain has on limestone. We also want to understand how acid can have an effect on rate of reaction. The word equation for the reaction that will take place is: Calcium Carbonate + Nitric Acid Calcium Nitrate + Carbon Dioxide + Water The balanced symbol equation
