The balanced chemical reaction:
C3H8 + 5O2 = 3CO2 + 4H2O
We are given the amount of the carbon dioxide to be produced. This will be the starting point of our calculations.
<span>43.62 L CO2 ( 1 mol CO2 / 22.4 L CO2 ) (5 mol O2 / 3 mol CO2 ) (
22.4 L O2 / 1 mol O2) = 72.7 L O2</span>
Answer:
a) acidic; [H+] = 10^-2.5 = 3 x 10^-3
b) basic; [H+] = 10^-11.7 = 2 x 10^-12
c) slightly acidic (almost neutral); [H+] = 10^-6.8 = 1.6 x 10^-7
d) acidic; [H+] = 10^-3.31 = 4.9 x 10^-4
Explanation:
pH < 7 is acidic; pH > 7 is basic; pH = 7 is neutral
[H+] = 10^-pH
Answer:
Multicellular Organism
Explanation:
Unicellular organisms are made of one cell. For example, bacteria. Multicellular organisms are made up of more than one cell. For example, humans.
If the entire organism is one cell, that one cell carries out all the functions. In contrast, we have different cells to carry out different jobs. E.g. blood cells, skin cells, stomach cells and many more.
