Which of the following statements are true at equilibrium? C. Consider the following reaction at equilibrium: 2A + 2B 2C + 2D + E If the concentration [E] is suddenly changed by a factor of two (halving [E]), what can be said about the changes in [A] and [B]? D. Consider the following chemical reaction: A+B C + 2D When Q < Keq for the above reaction, which of the following is true? E. Suppose 5.0 L of a solution of HBr(aq) is prepared. What will be the [HBr] at equilibrium in this solution its pH is measured to be 1.85?

The time between surface finish problems in galvanizing process is exponentially distributed with a mean of 40 hours. A single plant operates three galvanizing lines that are assumed to operate independently.a. What is the probability that none of the lines experiences a surface finish problem in 40 hours of operation.b. What is the probability that all three lines experience a surface finish problem between 20 and 40 hours of operation.3. In a digital communication channel, assume that the number of bits recevied in error can be modeled by a binomial random variable, and assume that the probabilitz that a bit is recived in error is 10^-5 . If 16 million bits are trasmitted, what is the probability that more than 150 errors occur?1.

Hello, I am looking for someone to write an essay on Climate change and H5N1. It needs to be at least 500 words.

This subtype virus was first discovered in 1960 in china. It was then discovered in Hong Kong as a direct transmission of the virus from birds to humans. Recent studies show that the wide spread statistics of the virus is reported over 60 countries in the world. Scientists have been on the look out to analyze whether the global climate change has any risk factors towards the widespread viral situation (Joan,138).

Different studies have been reported towards the virus highly pathogenic avian influenza viruses H5N1. Through understanding the causes of the condition mode of spread, findings can be concluded towards the effects of climate change as a risk factor. A number of studies will be analyzed here. Different years will be analyzed also. Data for the different continent spread is analyzed here through the periods when the global climatic effects were felt.

The disease influenza is caused by transmission of the virus from birds to humans. The predisposing risk factor is coming into contact with the virus. Research was done over the different continents from January 2004 to December 2009. Throughout this period, the epidemic waves are assessed.

Global warming that has enhanced the mosquito transmitting the virus to thrive in different continents. These have been felt largely in the northern America as well as Europe. The excessive heat during the early summer period has seen a huge outbreak of the disease. The mosquito transmits the bird in turn it enters the human systems.

The virus has been analyzed and seen to survive more effectively during the cold weather. This in turn leads to its wide spread during the winter and early summer. The global change in climate has cause a different trend in the movement of birds that carry the virus from Asia to other parts of the world. Their movement entails a longer stay in one place, lack of ordinary migration movement in time assessment, the length before stopping

The paper provides you with an opportunity to integrate and reflect on what you have learned during the class. The question to address is: “What have you learned about statistics?” In developing your responses, consider – at a minimum – and discuss the application of each of the course elements in analyzing and making decisions about data (counts and/or measurements). The course elements include:Descriptive statistics Inferential statistics Hypothesis development and testing Selection of appropriate statistical tests Evaluating statistical results.

What have you learned about statistics?Statistics is a vast subject which has lots of easy and hard topics and in this course we only wentthrough few of them.Now the elements we learned are…
