The legal question which must be addressed is any of the income that was earned by these individuals assessable income under the Australian income tax assessment act? To answer this question‚ we must determine if a nexus exists between Australia

A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms. The bond is caused by the electromagnetic force attraction between opposite charges‚ either between electrons and nuclei‚ or as the result of a dipole attraction. The strength of chemical bonds varies considerably; there are "strong bonds" such as covalent or ionic bonds and "weak bonds" such as dipole-dipole interactions‚ the London dispersion force and hydrogen bonding

Reaction on Reaction Paper The first thing that came to my mind when I have heard about Reaction paper is “What exactly is it?” and before I get an understanding of that‚ I resisted that change. But later‚ when I have studied about it and understood its purpose‚ I have started thinking “Why people avoid change at the first look without an analysis?” The general human tendency is to live in a comfortable zone in which he has lived for quite some time. He draws a circle‚ thinks that circle is his

this problem. Firstly the causes of this problem is the attitude of human. The human attitude nowadays really disappointing. They do not have the love feeling to the nature and throw garbage or any chemical substances anywhere including the river‚ the sea and any water sources. So this chemical substance will harm the water and we as the user will use the water without notice that we use the contaminated water. Slowly or in the long term our body will be affected.

Chemical Proportionality (Carbonate and Hydrochloric Acid) Introduction: The purpose of this experiment is what happens when a solid substance‚ a metal carbonate is added slowly to a solution of an acid. We are finding methods of determining acid concentration. For us to balance certain equations‚ we will use a stoichiometry. For this experiment‚ we will need to set up the ratio and finding the concentration of HCI. Procedure: • Grab 4 different beakers. • Add a small amount of sodium carbonate
