I think the correct answer from the choices listed above is option A. When you drink <span>milk of magnesia for an upset stomach, most likely, it would raise the pH in your body since it reacts with the acid inside reducing the amount of acid. Hope this answers the question.</span>
Answer:
116.3 kJ
Step-by-step explanation:
Three heat transfers are involved
q = Heat to warm ice + heat to melt ice + heat to warm water + heat to evaporate water + heat to warm steam
q = q₁ + q₂ + q₃ + q₄ + q₅
q = mC₁ΔT₁ + mΔH_fus + mC₃ΔT₃ + mΔH_vap + mC₅ΔT₅
<em>Step 1</em>: Calculate q₁
m = 37.0 g
C₁ = 2.010 J·°C⁻¹g⁻¹
ΔT₁ = T_f – T_i
ΔT₁ = 0.0 – (-10.0)
ΔT₁ = 10.0 °C
q₁ = 37.0 × 2.010 × 10.0
q₁= 743.7 J
q₁= 0.7437 kJ
===============
<em>Step 2</em>. Calculate q₂
ΔH_fus = 334 J/g
q₂ = 37.0 × 334
q₂ = 12 360 J
q₂ = 12.36 kJ
===============
Step 3: Calculate q₃
C₃ = 4.179 J·°C⁻¹g⁻¹
ΔT₃ = T_f – T_i
ΔT₃ = 100 – 0
ΔT₃ = 100 °C
q₃ = 37.0 × 4.179 × 100
q₃ = 15 460 J
q₃ = 15.46 kJ
===============
<em>Step 4</em>. Calculate q₄
ΔH_vap = 2260 J/g
q₄ = 37.0 × 2260
q₄ = 83 620 J
q₄ = 83.62 kJ
===============
<em>Step 5</em>. Calculate q₅
C¬₅ = 2.010 J·°C⁻¹g⁻¹
ΔT₅ = T_f – T_i
ΔT₅ = 155.0 – 1000
ΔT₅ = 55.0 °C
q₅ = 37.0 × 2.010 × 55
q₅ = 4090 J
q₅ = 4.090 kJ
===============
Step 6. Calculate q
q = 0.7437 + 12.36 + 15.46 + 83.62 + 4.090
q = 116.3 kJ
The heat required is 116.3 kJ.
Answer:
the melting point is the factor what what degrees fahrenheit a metal or other solid substance melts. the significance of knowing the melting point can help you determine how long or how hot to burn the tested object while at the same time determining the safety requirements.
