The volume would increase and it will become 4.00 L
The atoms on the products side are bonded into different molecules from the atoms on the reactants side is the chemical changes occured.
<u>Explanation:</u>
- The reaction commences when the compounds on the reactant side are ready to react to give the product.
- The reaction initiated by the transfer of electrons and molecules from the reactants to give the combined product of both the reactants.
- It is a process on which there will be rearrangement in the structure of molecules of a substance from its physical for more chemical form.
- In the above picture it shown that the red molecules combined with the white molecules additionally and changed the structure.
Answer:
Calculate the pOH for a solution with a hydroxide ion, (OH-) of concentration of 6.49 X 10-11 M.
Calculate the pH.
Note: the answers should have three significant figures
The pOH is: Blank 1
The pH is: Blank 2
Explanation:
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.
