Explanation:
4 Fe + 3 O₂ → 2 Fe₂O₃
On the left side, there are 4 Fe atoms and 6 O atoms.
On the right side, there are 4 Fe atoms and 6 O atoms.
The reaction is balanced.
Answer:
The entropy change of the sample of water = 6.059 x 10³ J/K.mol
Explanation:
Entropy: Entropy can be defined as the measure of the degree of disorder or randomness of a substance. The S.I unit of Entropy is J/K.mol
Mathematically, entropy is expressed as
ΔS = ΔH/T....................... Equation 1
Where ΔH = heat absorbed or evolved, T = absolute temperature.
<em>Given: If 1 mole of water = 0.0018 kg,</em>
<em>ΔH = latent heat × mass = 2.26 x 10⁶ × 1 = 2.26x 10⁶ J.</em>
<em>T = 100 °C = (100+273) K = 373 K.</em>
<em>Substituting these values into equation 1,</em>
<em>ΔS =2.26x 10⁶/373</em>
ΔS = 6.059 x 10³ J/K.mol
Therefore the entropy change of the sample of water = 6.059 x 10³ J/K.mol
Answer:
T = 2π/ω = 2π / √(k/m) = 2π / √(60/5) = 1.813... about 1.8 s
Explanation:
Current<span> is nothing but the flow of charges due to the potential </span>difference<span>, whether its an electronic </span>circuit<span> or an </span>electrical circuit<span>.
</span>
It is a vector quantity.
its the tendency of force to cause a body to rotate about a point or axis. so its vector.
