Answer:
Oxidized,Reduced,reductant,oxidant, NAD+,NADH
Explanation:
1 when a compound donates electrons the compound becomes oxidized.such a compound is referred to as electron donor.
2 when a compound accept electron the compound becomes reduced such a compound often referred to as electron acceptor.
3 In glycolysis once the carbon containing compound that functions as electron donor is reductant.
4 once the electron donor in glycolysis gives up its electron ,it is oxidized to a compound called oxidant.
5 NAD+ is the compound that function as electron acceptor in glycolysis.
6 The reduced form of electron acceptor in glycolysis is NADH.
The mass of a mole of Cu₂O is basically the molar mass of this compound. To find this, add the molar mass of each atom in the compound together. Therefore you will get 62x2 + 16 = 140 grams
Answer:
Pour the mixture through a filter to separate the sand, then evaporate the liquid to separate the salt.
