2. What net ionic equation describes the reaction that occurs when Al2(SO4)3(aq) and Na3PO4(aq) are mixed together? 3Na+(aq) + PO43-(aq) - 3Naso (s) + A13+ (aq)
A13+(aq) + PO43-(aq) - AlPO4(s)
35042-(aq) + 3Na+(aq) - Naso,(s)
Al3+ (aq) + PO43-(aq) + 350,2-(aq) - 3 AlPO4(s) + 3Na+(aq)

Ithink the correct answer is 3

Polyethylene is a strong synthetic polymer that can be used to make toys and bottles. this makes plastics which are important also to people but sometimes it lead to harmful environmental effects such as global warming if these plastics are burned.

The chlorine is the chemical property 

In order to improve results, many different steps can be taken into account. 1) using more precise scales and thermometers is always something that should be considered as being precise means that you are more exact with your answer.2) increasing the sample size should also be considered, if you have a bigger sample size you are able to determine if your results are accurate as well as if there are any variables that should be taken into account plus it assists in the statistical analysis and produces overall better data3) using better handwriting is also a plus, along with organizing the data properly so that others are also able to read the results and even redo the experiment in the future if it is needed.
