A solution was prepared by mixing 50.00 ml of 0.100 M of HNO3 and 100.00 ml of 0.200 M HNO3. Calculate the molarity of the final
valentina_108 [34]

Answer:

The molarity of this final solution is 0.167 M

Explanation:

Step 1: Data given

Volume of a 0.100 M HNO3 solution = 50.0 mL

Volume of a 0.200 M HNO3 = 100.0 mL

Step 2: Calculate moles

The final molarity must lie between 0.1M and 0.2M  

Moles = molarity * volume

Moles HNO3 in 50mL of a 0.100M solution = 0.05 L *0.100 M = 0.005 mol

Moles HNO3 in 100mL of a 0.200M solution = 0.100 L*0.200 = 0.020mol

total moles = 0.005+0.020 = 0.025 moles in 150mL solution = 0.150L

Step 3: Calculate molarity of final solution

Molarity = mol / volume

Molarity 0.025 moles /0.150  L

Molarity = 0.167M

The molarity of this final solution is 0.167 M

Would you expect a heavily crosslinked polyethylene that has a glass-transition temperature of 0°c to be an elastomer, a thermos
musickatia [10]

The heavily crosslinked polyethylene that has a glass-transition temperature of 0°c to be an <u>thermoset (non-elastomer).</u>

A cross-linked kind of polyethylene has been known as cross-linked polyethylene, sometimes known by the acronyms PEX, XPE, or XLPE. It must be primarily utilized in residential water piping, high tension electrical cable insulation, hydronic radiant heating as well as cooling systems, construction management pipework systems, and infant play mats.

Tanks composed of linear polyethylene as well as XLPE are both constructed using heated resins to produce cured plastic. But because of the variations in how they are produced, the polyethylenes they produce have extremely varied structural strengths. Simply put, cross-linking is just the creation of links between polymer chains.

Therefore, the correct answer will be option (a).
