Answer:
The sound wave travelled more quickly through the glass of water than the metal pole.
The sound wave travelled the fastest through the helium.
The sound wave travelled the slowest through the metal pole.
These 3 are most likely true.
<u>If you have to </u><u>pick</u><u> </u><u>just</u><u> </u><u>one</u><u>,</u> the sound wave travelled the fastest through the helium.
You did not include the options but I can tell you the product ratio.
The product ratio is the mole ratio of the products of the reaction.
From the balanced chemical equation you have all the mole ratios:
The given equation is: 2 C6H5COOH + 15O2 --> 14 CO2 + 6H2O
The mole ratios are: 2 C6H5COOH: 15 O2: 14 CO2 : 6 H2O
The products are CO2 and H2O
Their mole ratio = 14 CO2 : 6 H2O
That can be expressed as:
14 mol CO2 7 mol CO2
----------------- = -----------------
6 mol H2O 3 mol H2O
It is also the same that:
6 mol H2O : 14 mol CO2
6 mol H2O 3 mol H2O
------------------ = -------------------
14 mol CO2 7 mol CO2
So, compare your options to the ratios show above and pick the proper ratio.
Pure substances are made of the same material and have almost the same properties such as: Carbon, Iorn, Water, Sugar, Salt, and Nitrogen.
