It is responsible for exchange of gases of oxygen and carbondiòxide and in this process energy is also released in form of glucose
I think it’s I
Iodine has 53 protons and 74 neutrons
Answer:
a) Q = 0.025 KJ/g
b) Q = 0.602 KJ/mol
Explanation:
ΔU = Q + W.....first law
∴ a constant volume: ΔV = 0
⇒ W = 0
⇒ ΔU = Q = CvΔT
∴ Cv = 3.024 J/°C
∴ ΔT = 1.126 °C
⇒ Q = (3.024 J/°C)×(1.126 °C ) = 3.405 J
⇒ Q = 3.405 E-3 KJ
a) Q [=] KJ/g
⇒ Q = (3.405 E-3 KJ) / (0.1375 g) = 0.025 KJ/g
b) Q [=] KJ/mol
∴ Mw Mg = 24.305 g/mol
⇒ Q = (0.025 KJ/g)×(24.305 g/mol) = 0.602 KJ/mol
Explanation:
(1) Nuclear reactions involve a change in an atom's nucleus, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei. ... (3) Rates of chemical reactions are influenced by temperature and catalysts.
5 dots since the lewis dot diagram only shows the valence electrons (please give me brainliest)
