The purpose of this lab was to find my and my fellow classmates resting heart rate and record it. There were seven people in the class and we all participated in this study. There are four places to check heart rate and they are in your wrist‚ the inside of your elbow‚ the side of your neck‚ or the top of your foot. Everyone used the wrist or their radial artery. We used our middle and index fingers to gently feel for the radial artery in each others pulse. I then counted the pulse for 10 seconds

calculate the fraction that will be used up after 6.0 minutes. 4. [15 points] The rate law for the decomposition of ozone to molecular oxygen 3 O3 (g) −→ 3 O2 (g) is rate = k [O3 ]2 . [O2 ] The mechanism for this process is k1 O3 O + O2 k−1 k 2 O + O3 −→ 2 O2 Derive a rate law from these elementary steps. Clearly state the assumptions you use in the derivation. Explain why the rate decreases with increasing O2 concentration. 5. [15 points] Consider the following

Identity theft is one of the fastest growing crimes in the United States. In the year 2014 according to the Javelin Strategy & Research group‚ $16 billion dollars were stolen from 12.7 million identity fraud victims. (Javelin Strategy & Research‚ 2015) Many cases of identity theft usually go unreported and the numbers could be higher according to the USA today which estimates 130 million from about 1 million in the year 2007. (Anderson J. G.‚ 2013) In today age and time‚ identity theft is becoming

The Rate Of Photosynthesis: Lab report 1) Construct a graph of your data 2) Using the graph‚ estimate the time at which 50 percent of the leaf disks were floating on the surface. The point at which 50 percent of the leaf disks are floating will be you point of reference for future investigations Using the graph the estimated time that roughly 50% of the leaf disks were floating on the surface was around the 10th minute. At the 10th minute our number rose up to

kinds of rat snakes. One‚ of which is the Black Rat snake. The black Rat snake is a non-venomous snake that can grow up to eight feet in length. The adults are mostly black‚ with white bellies‚ and have white or gray showing between their scales. The young‚ or juvenile‚ usually are brown or gray with dark colored splotches on their backs. Black Rat snakes are very common in the southeast. They are also called the Common Rat Snake for they are more likely to be found than any of the other rat snakes

What Substance Will Melt Ice the Fastest Have you ever wondered which substance melt ice the fastest? My question is how does the material on ice effect the rate the ice melts? To test this I will put sand‚ sugar‚ and salt on ice in separate containers. Next I will check every hour after I put the ice in the refrigerator to watch until one container’s ice has been half melted. To keep this experiment valid I will keep the amount of ice‚ the time‚ and the amount of materials the same. In my experiment

The Correlation between the Diffusion Rate of a Substance and its Molecular Weight ABSTRACT To test the effect of molecular weight on the rate of diffusion‚ various experiments were performed. One of which is the glass tube test wherein cotton balls of the same size were moistened in two different substances (NH4OH and HCl). These cotton balls were plugged at each side of a glass tube. After some time‚ formation of a white ring occurred. The white ring‚ in fact‚ is a product of the reaction between
