Answer:
D.
Explanation:
NH3 (Ammonia) is a water soluble gas, and is polar. While C6H14 is non-polar and does not mix with water soluble.
If you don't wash the thermometer, residual NaOH will react with the HCl solution. This is a highly exothermic reaction and will change the temperature of the solution, and thus throw off your measurement.
Answer:
2AgNO3 + Cu = Cu(NO3)2 + 2Ag
Explanation:
First you see which side has the most elements. Which is Cu(NO3)2 + Ag. But, both sides have the same elements? But, on the reactants side, there is 2 of NO3. On the products side there is only one.
Reactants: Products:
Cu = 1 Cu = 1
NO3 = 1 NO3 = 2
Ag = 1 Ag = 1
They are all equal, except for NO3. So on the reactants side, you add a two to make it even.
2AgNO3 + Cu = Cu(NO3)2 + Ag
Reactants: Products:
Cu = 1 Cu = 1
NO3 = 2 NO3 = 2
Ag = 2 Ag = 1
Now, the NO3 is equal, But the Ag isn't. But, you can add a 2 on the <u>products</u> side so the whole equation becomes equal.
2AgNO3 + Cu = Cu(NO3)2 + 2Ag
Reactants: Products:
Cu = 1 Cu = 1
NO3 = 2 NO3 = 2
Ag = 2 Ag = 2
