The boiling point would be measured as C) 373 Kelvin
Answer is: <span>1.0×10</span>¹⁶.<span>
</span>P (power of laser) = 3,2 mW = 0,0032 W.
λ (wavelength) = 633 nm = 633 · 10⁻⁹m = 6,33·10⁻⁷m.
P = n·h·c÷λ ⇒ n = n=P·<span>λ/h</span>·<span>c.
</span>c -<span> speed of light </span><span>3⋅10</span>⁸ <span>m/s.
h - </span><span>Planck's constant - </span><span>6.63⋅10</span>⁻³⁴J·<span>s.
n - number of photons emited.
n = 0,0032W </span>· 6,33·10⁻⁷m / 6.63⋅10⁻³⁴J·s · 3⋅10⁸ m/s
n = 1·10¹⁶ 1/s.<span>
</span>
The chemical reaction is
<span> M2+(aq) + 2L(aq) <==> ML22+(aq)
</span>Intial concentration 0.10 0.10
Change -x -2x +x
Equilibrium 0.10 - x 0.01 = 0.10 - 2x x
Solving for x
0.01 = 0.10 - 2x
x = 0.045
The equilibrium concentration of ML22+ is 0.045 mol L-1
Answer:The perimeter of the rectangle is or 15.66 inch.
Explanation:
Length of strip (I) =
Length of strip (II) =
According to question two strips of length and two strips of lenght is used in making rectangle:
Perimeter of rectangle = Sum of all sides of rectangle
Perimeter of rectangle =
The perimeter of the rectangle is or 15.66 inch.
