It requires 334 kJ of heat to melt 1 kg of ice. The largest known iceberg had a volume of about 3.1 x 1013 m³. How much heat was
umka21 [38]

The  amount of heat required to melt the iceberg at 9.58 * 10¹⁸ kJ.

<h3>What is the amount of heat required to melt an iceberg that has a volume of about 3.1 x 1013 m³?</h3>

The heat required to melt a unit mass of ice is known as the latent heat of fusion.

The latent heat of fusion of ice of 1 kg= 334 kJ of heat

Mass of iceberg = 3.1 x 10¹³ m³ * 917 kg = 2.8427 * 10¹⁶ kg

Amount of heat required = 2.8427 * 10¹⁶ * 334 = 9.58 * 10¹⁸ kJ.

Therefore, the amount of heat required to melt the iceberg at 9.58 * 10¹⁸ kJ.

given the following equation: 8 H2 + S8 −−&gt; 8H2S what is the molar relationship between H2 and H2S
PSYCHO15rus [73]
-(1/8)Δ[H2S]/Δt = -(1/4)Δ[O2]/Δt
(1/8)Δ[H2S]/Δt = (1/4)Δ[O2]/Δt
(4)*((1/8)Δ[H2S]/Δt) = (4*)((1/4)Δ[O2]/Δt)
(1/2)Δ[H2S]/Δt = Δ[O2]/Δt
(1/2))*( -0.057 M/s) = Δ[O2]/Δt
Δ[O2]/Δt = -0.0285 M/s
