Answer:
Sgen = 0.0366 W/K
Explanation:
for the body:
∴ Q = - 336 W...rate of heat loss
∴ T surface = 35°C ≅ 308 K
the rate of entropy transfer from the body:
⇒ ΔS = - Q/Ts
for the enviroment:
⇒ ΔS = Q/Te
∴ assuming: T = Tenv = 25°C ≅ 298 K
resulting in a net variation in the universe:
⇒ Sgen = ΔS = Q/Tenviroment - Q/Tsurface = Q(Ts - Te)/Ts*Te
⇒ Sgen = (336( 308-298))/(308×298) = 3360 WK/91784 K² = 0.0366 W/K
Answer:
A higher concentration will increase rate of reaction because in a conc substance the particles are more clustered together and this causes more effective collisions thus increasing the rate of reaction.
Kidneys work with other body systems to maintain homeostasis by working with other body systems such as the respiratory system.

<span>Mg + O2 > MgO. In reactant side, 2 O atoms and 1 Mg are present. In product side, 1 Mg and O atoms are present. Put 2 in product side to balance O atoms and 2 at Mg in reactant side to balance Mg atoms. Therefore the balanced equation becomes, 2Mg + O2 ----> 2MgO. Hope it helps.</span>
