You get 42 when you multiply 6 & 7.
Okay so, 24.00 mL of a 0.25 M NaOH solution is titrated.
Answer:
Both are endothermic reactions.
Explanation:
Chemical equation:
1/2H₂(g) + 1/2I₂(g) → HI(g) + 6.2 kcal/mol
Chemical equation:
21.0 kcal/mol + C(s) + 2S(s) → CS₂
Both reaction are endothermic because heat is added in both of reactions.
Endothermic reactions:
The type of reactions in which energy is absorbed are called endothermic reactions.
In this type of reaction energy needed to break the bond are higher than the energy released during bond formation.
For example:
C + H₂O → CO + H₂
ΔH = +131 kj/mol
it can be written as,
C + H₂O + 131 kj/mol → CO + H₂
Exothermic reaction:
The type of reactions in which energy is released are called exothermic reactions.
In this type of reaction energy needed to break the bonds are less than the energy released during the bond formation.
For example:
Chemical equation:
C + O₂ → CO₂
ΔH = -393 Kj/mol
it can be written as,
C + O₂ → CO₂ + 393 Kj/mol
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.
Answer:first one is chemical change and the second one is chemical reaction that sh be right.
