Answer:The energies of infrared photons are in the same range as the energies associated with different vibrational states of chemical bonds. Molecules can absorb infrared photons of characteristic wavelengths, thus revealing the types and strengths of different bonds in the molecules.
Explanation:
Infrared spectroscopy measures the vibrational energy levels in a molecule. When a molecule absorbs Infrared photons, the chemical bonds vibrate at different frequency. An analysis of the changes in vibrational energy within a molecule can be used to ascertain the different kinds of bond and hence the overall structure of the molecule. The vibrational modes of a molecule includes; bending, stretching and scissoring.
Petroleum is a mixture of hydrocarbons. Each hydrocarbon consists of carbon and hydrogen atoms. A hydrocarbon contains carbon chain and its boiling and melting points increase with increase in length of the carbon chain. The length of the carbon chain increases with increase in the number of carbon atoms forming bonds. Therefore, the boiling point of hydrocarbon increases with increase in the number of carbon atoms.
(Answer) (2) increase in the number of carbon atoms.
Answer:
0th order with respect to oxygen.
Explanation:
Whenever we have a table with the molarity of a substance against time, the best idea is to input the time into one cell of Excel and molarity into the other adjacent cell of Excel.
We wish to produce 3 plots: plot 1 would contain time on the x-axis and molarity values on the y-axis. In case we get a straight line in the graph, we can verify that this is a 0th order reaction.
Plot 2 would need us to calculate the natural logarithm of each concentration and plot time on the x-axis and ln of each molarity on the y-axis. In case we get a straight line, we can verify a 1st order reaction.
Plot 3 would require calculating the reciprocal of each molarity, that is, 1/[O2] in each case. Plotting time on the x-axis and 1/[O2] on the y-axis would yield a graph. In case this graph is linear, then the reaction order is 2nd.
We plot each graph and add trendline in Excel. None of the graphs is perfectly linear, so the only data we can rely on is the R-squared coefficient. The closer it is to 0, the closer your points resemble a line. Out of all three graphs, the highest R-squared value is seen for the 0th order rate law at a value of 0.8721 against 0.7749 for the 1st and 0.6255 for the second.
You may wish to refer to the Excel file for the details.
There are two types of vesicular transport processes, exocytosis and endocytosis. Endocytosis is the process which is involved in the toxin entering the neuron. This process is where cells intake waste or chemical transmitters which are suspended or dissolved in the extracellular fluid around the cell. <span />
The answer is Eukaryotic cells.
