What is it meant by relative formula mass? How is it calculated using the periodic table? Each element has a relative atomic mass. When a compound is made‚ these relative atomic masses are added together to calculate the relative formula mass of the substance. For example the atomic mass of Na is 23 and the atomic mass of Cl is 35.5 so the relative formula mass of NaCl is 58.5 How by using RFM is it possible to work out amounts of a substance in terms of moles? The compound I was using in my

Evaluate the relative roles of natural succession and human activities in the creation of ecosystems within the British isles. (40 marks) An ecosystem is a biological community of interacting organisms and their physical environment. Ecosystems can be changed by both human activity and natural succession. Ecological succession is the observed process of change in the species structure of an ecological community over time. The time scale can be decades (for example‚ after a wildfire)‚ or even millions

of referencing and incorporating all three religions served to remind us that Pi had no different view on the three. Pi’s view on religion ties in greatly with relative truth as Pi sees the correct religion to be the one you see most credible‚ but relative truth can be seen in our entire lives not just religion. A memorable moment of relative truth lies in the ending; Martel ends the book with two different stories. One story sticks to the book involving animals‚ and the other replaces the animals

n the differences between absolute and relative morality Relativism and absolutism are two ethical theories that strongly differ in beliefs and opinions. A relativist person would believe that there are no absolute universal truths‚ truth is relative to the subject and can differ from person to person and society to society. Relativism considers the outcome of choices; a relativist will generally make decisions based on the likely outcome. On the other hand‚ an absolutist thinker believes that

Biology 301 12/3/2012 The Effects of Relative Fitness of Drosophila Melanogaster on Evolution Abstract This experiment was conducted to study the relative fitness of two phenotypes of the Drosophila melanogaster and how fitness can affect evolution in the population. The phenotypes were placed in two different environments‚ one in which contained a predator and another with no predator. Results of the experiment would show how the fitness of each phenotype is affected by providing a mechanism
