Na is the reducing agent since it is being oxidized
Explanation:
both iron and sulphur in FeS2 undergo a change in oxidation state.
O2° -->2O degree2- Total decrease = 2×2=4
So, 4FeS2+11O2 --> 2Fe2O3+8 SO2
Hence, balanced
The answer that fits the given blank above is the term ASSIMILATION. In the process of assimilation, there is a large production of organic nitrogen and this includes amino acids, other proteins, and nucleic acids. This is when nitrogen is converted into ammonia.
For the first question, salt is soluble while sand is insoluble or not dissolvable in water. The salt should have vanished or melted, but the sand stayed noticeable or visible, making a dark brown solution probably with some sand particles caught on the walls of the container when the boiling water was put in to the mixture of salt and sand. The solubility of a chemical can be disturbed by temperature, and in the case of salt in water, the hot temperature of the boiling water enhanced the salt's capability to melt in it.
For the second question, the melted or dissolved salt should have easily made its way through the filter paper and into the second container, while the undissolved and muddy sand particles is caught on the filter paper. The size of the pores of the filter paper didn’t change. On the contrary, the size of the salt became smaller because it has been dissolved which is also the reason why it was able to go through the filter paper, while the size of the sand may have doubled or even tripled which made it harder to pass through.
Answer:
The energy released during the sudden ground motion comes from a build up over long periods of time, as a result of tectonic forces within the earth. Plate boundaries are made up of many faults. The edges of these faults are not smooth like a table top but are rough
