3. How many more troops did the Union states have than the Confederate states?

lions [1.4K]

At the beginning of the war the Northern states had a combined population of 22 million people. The Southern states had a combined population of about 9 million. This disparity was reflected in the size of the armies in the field. The Union forces outnumbered the Confederates roughly two to one.

Calculate the enthalpy change, ∆H in kJ, for the reaction H2O(s) → H2(g) + 1/2O2(g). Use the following information: : +279.9 kJ

Len [333]

Answer:

+ 291.9 kJ

Solution:

The equation given is as;

H₂O ₍s₎ → H₂ ₍g₎ + 1/2 O₂ ₍g₎ ΔH = ?

First, as we know the heat of formation of H₂O ₍l₎ is,

H₂ ₍g₎ + 1/2 O₂ ₍g₎ → H₂O ₍l₎ ΔH = - 285.9 kJ

Now, reversing the equation will reverse the sign of heat as,

H₂O ₍l₎ → H₂ ₍g₎ + 1/2 O₂ ₍g₎ ΔH = + 285.9 kJ

Also, we know that,

H₂O ₍s₎ → H₂O ₍l) ΔH = + 6.0 kJ

Now, adding last two equations,

H₂O ₍l₎ → H₂ ₍g₎ + 1/2 O₂ ₍g₎ ΔH = + 285.9 kJ

H₂O ₍s₎ → H₂O ₍l) ΔH = + 6.0 kJ

-----------------------------------------------------------------------------

H₂O ₍s₎ → H₂ ₍g₎ + 1/2 O₂ ₍g₎ ΔH = + 291.9 kJ

Research three different types of fire extinguisher and explain how these can be used to put out different fires, you must relat

Vilka [71]

The fire triangle is composed of
1) heat
2) fuel
3) oxidizing agent (oxygen)

Types of fire extinguishers:
1) Water and Foam - extinguish the fire by taking away the heat element of the fire triangle. Foam agents separate the oxygen element from the other elements.
2) Carbon dioxide - extinguish fire by taking away the oxygen element of the fire triangle and also be removing the heat with a very cold discharge.
3) Dry Chemical - extinguish the fire primarily by interrupting the chemical reaction of the fire triangle.
4) Wet Chemical - extinguishes the fire by removing the heat of the fire triangle and prevents re-ignition by creating a barrier between the oxygen and fuel elements
5) Clean Agent - extinguish the fire by interrupting the chemical reaction of the fire triangle
6) Dry Powder - extinguish the fire by separating thefuel from the oxygen element or by removing the heat element of the fire triangle
7) Water Mist - extinguish the fire by taking away the heatelement of the fire triangle
8) Cartridge Operated Dry Chemical - extinguish the fire primarily by interrupting the chemical reaction of the fire triangle
