Answer:
Explanation:
To convert gram / centimeter³ to kg / m³
gram / centimeter³
= 10⁻³ kg / centimeter³
= 10⁻³ / (10⁻²)³ kg / m³
= 10⁻³ / 10⁻⁶ kg / m³
= 10⁻³⁺⁶ kg / m³
= 10³ kg / m³
So we shall have to multiply be 10³ with amount in gm / cm³ to convert it into kg/m³
2.33 gram / cm³
= 2.33 x 10³ kg / m³ .
Answer:
<em>waxing gibbous moon</em>
<em>It comes a week after new moon. <u>A waxing gibbous moon</u> occurs when more than half of the lit portion of the Moon can be seen and the shape increases ("waxes") in size from one day to the next. The waxing gibbous phase occurs between the first quarter and full moon phases.</em>
Answer:
A. (1/T₂ - 1/T₁) = -2.69 x 10⁻⁴ K⁻¹
B. ln (k₁/k₂) = -3.434
C. E = 106.13 KJ/mol
Explanation:
Part A:
we have:
T₁ = 25°C = 298 K
T₂ = 51°C = 324 K
(1/T₂ - 1/T₁) = (1/324 k - 1/298 k)
<u>(1/T₂ - 1/T₁) = -2.69 x 10⁻⁴ K⁻¹</u>
<u></u>
Part B:
ln (k₁/k₂) = ln (0.1/3.1)
<u>ln (k₁/k₂) = -3.434</u>
Part C:
The activation energy can be found out by using Arrhenius Equation:
ln (k₁/k₂) = E/R (1/T₂ - 1/T₁)
where,
E = Activation Energy
R = General Gas Constant = 8.314 J/mol.k
Therefore,
-3.434 = (E/8.314 J/mol.k)(-2.69 x 10⁻⁴ K⁻¹)
<u>E = 106134.8 J/mol = 106.13 KJ/mol</u>
