Hard water

is now being stressed due to the reduced water flow down the Chattahoochee and Flint River systems. These river systems flow into the Apalachicola River and then to the Apalachicola River basin. This reduced flow is changing salinity levels, which in turn is having a negative impact on the health of the entire ecosystem of the river and river basin. Many species are dying off, and it is feared some to extinction. The oyster industry is particularly hard hit. An entire way of life…

1) First, melting candle wax is a physical change. When heated, the candle wax, which is opaque, white and has a hard, waxy feeling, changed from a solid to a liquid. The hot wax became more of a transparent white and after cooling time, the hot wax changed back into a solid. Changing back into its original state suggests physical change. But, burning candle wax shows evidence of both physical and chemical change. The melting of the wax is an example of physical change, the heat source caused…

The net forms a partial barricade and aims to entangle and capture sharks of targeted species, through holes that entangle sharks over two metres. Shark culling is being carried out in Australia with the desire that those using the beach and its water for recreational activities are less likely to be attacked. It is also thought that shark culling is in place as Australia's tourism is heavily reliant on eco-touristic activities. The principle of shark culling is: the more sharks…

Water Hardness EEI Water is a covalent molecule and is formed between one oxygen atom and two hydrogen atoms. This is because oxygen needs to gain two electrons to become like neon and hydrogen needs to gain one electron to become like helium so they share electrons for each hydrogen atom and the oxygen atom ‘consider’ that they have achieved the noble gas configuration. This covalent bond forms a bent shape in order to share the necessary electrons. Water has many unique properties, one of…

To be honest, I do not…
