Answer:
-7.2 * 10^4 kJ mol-1
Explanation:
First we obtain the change in enthalpy for the reaction;
ΔHrxn= ΔHproducts - ΔHreactants
ΔHrxn=[( −510 ) - (−110.53) + (−277.69)]
ΔHrxn= -121.78 * 3 J mol-1
The we obtain the entropy change of the reaction
ΔSrxn= ΔSproducts - ΔSreactants
ΔSrxn= [(191) - (197.67) + (160.7)]
ΔSrxn= -167.37 J K-1 mol−1
Then we calculate ΔG at 298 K
ΔG = ΔH - TΔS
ΔG = ( -121.78 * 3) - (298) (-167.37)
ΔG = -7.2 * 10^4 kJ mol-1
Among the choices, the only unicellular organism is bacteria. <span>The bacteria has no nucleus, and no distinct organelles. </span>Bacteria only has one cell, where all of its life processes take place, like respiration, ingestion, and excretion, so it can survive only as a single cell.
Answer:
156.1 rad/s = 24.8 rev/s
Explanation:
Torque = Momentum of inertial × radial acceleration = Iα
τ = 26.6 N.m
I = 0.162 kg.m²
26.6 = 0.162 × α
α = 164.2 rad/s²
Using equations of motion,
θ = 11.8 rev = 11.8 × 2π = 74.2 rad
w₀ = 0 rad/s (since the grindstone starts from rest)
w = ?
α = 164.2 rad/s²
w² = w₀² + 2(α)(θ)
w² = 0² + (2×164.2)(74.2)
w = 156.1 rad/s = 24.8 rev/s
Hope this Helps!!!
Answer:
no
Explanation:
the metal spoon would be higher temperature
Answer:
Transverse wave
Explanation:
Its because in transverse wave the particle displacement is perpendicular to the direction of wave propagation..hope it helps you...
