Answer:- 335 kcal of heat energy is produced.
Solution:- The balanced equation for the combustion of glucose in presence of oxygen to give carbon dioxide and water is:
From given info, 2803 kJ of heat is released bu the combustion of 1 mol of glucose. We need to calculate the energy produced when 3.00 moles of oxygen react with excess of glucose.
We could solve this using dimensional analysis as:
= 1401.5 kJ
Now, let's convert kJ to kcal.
We know that, 1kcal = 4.184kJ
So,
= 335 kcal
Hence, 335 kcal of heat energy is produced by the use of 3.00 moles of oxygen gas.
Answer:
Ferrous hydroxide or iron (II) hydroxide.
Explanation:
Hello,
In this case, for the nomenclature of hydroxides we can use two styles:
a. IUPAC: it points out the oxidation state of the given metal by using suffixes ous or ic for metals having to oxidation states, thus, since +2 for iron is the first one, it turns out ferrous hydroxide.
b. Stock: it points out the oxidation state of the given metal by writing it inside parenthesis, thus, it turns out iron (II) hydroxide.
Regards.
