The prefix 'di' means two. Hence two atoms make up a diatomic molecule.

Answer:
The catabolic process of converting carbohydrates to CO2 requires<u> oxidation</u> of carbon.
Explanation:
There are multiple definitions of reduction-oxidation. There is one that explains it with respect to oxygen, the other with respect to hydrogen and another with respect to electrons. The relevant one here is the one that explains it in terms of hydrogen. Oxidation is the removal of hydrogen while reduction is the addition of hydrogen. During repiration, the carbon loses the hydrogens attached to it and is therefore oxidized. These hydrogens attach themselves to oxygen which means oxygen is reduced.
Answer:
1.87 J
Explanation:
q = c x m x (T2-T1)
c- specific heat of water (4.186 j/g.C)
q = 4.186 x 0.5137 x 0.871 = 1.87 J
Explanation:
Element Symbol Mass Percent
Calcium Ca 38.763%
Oxygen O 41.265%
Phosphorus P 19.972%
439.3 g CO2
Explanation:
First find the # of moles of CO2 that results from the combustion of 3.327 mol C3H6:
3.227 mol C3H6 × (6 mol CO2/2 mol C3H6)
= 9.981 mol CO2
Use the molar mass of CO2 to determine the # of grams of CO2:
9.981 mol CO2 x (44.01 g CO2/1 mol CO2)
= 439.3 g CO2
