Answer:

627.6J

Explanation:

q=mcΔT

where:

q = heat energy (J)

m = mass (g)

c = specific heat (g/j*C)

Δt = change in temperature (C/K)

q= (150)(4.184)(1) = 627.6

For the simple decomposition reactionAB(g)→ A(g) + B(g)Rate =k[AB]2 and k=0.2 L/mol*s . How long will it takefor [AB] to reach 1
mixer [17]

Answer:

6.66 s will it take for [AB] to reach 1/3 of its initial concentration 1.50 mol/L.

Explanation:

Rate = k[AB]^2

The order of the reaction is 2.

Integrated rate law for second order kinetic is:

\frac{1}{[A_t]} = \frac{1}{[A]_0}+kt

Where, [A_0] is the initial concentration  = 1.50 mol/L

[A_t] is the final concentration  = 1/3 of initial concentration = \frac{1}{3}\times 1.50\ mol/L = 0.5 mol/L

Rate constant, k = 0.2 L/mol*s

Applying in the above equation as:-

\frac{1}{0.5} = \frac{1}{1.50}+0.2t

\frac{1}{1.5}+0.2x=\frac{1}{0.5}

t = 6.66\ s

<u>6.66 s will it take for [AB] to reach 1/3 of its initial concentration 1.50 mol/L.</u>

Answer:

That is the membrane of the cell

Explanation:

The cell membrane is made up of layers of protein and fat. It is made with a <em>phospholipid bilayer</em>. It allows some substances to pass into the cell while blocking others. This is known as <em>semipermeability</em>.
