The correct answer is:
TRIGONAL PYRAMIDAL
85-12 = 73 degrees needed
4.186 J/degree Celsius, so
73 degrees * 4.186 J/degree = 305.578 J to raise 1 gram 73 degrees
there are 675 grams, so 305.578 * 675 = 206265.15 J
2.06 x 10^5 J are needed
Explanation:
Pressure of a gas is the combined force with which the molecules bombard a unit area of the wall of the container.
1 atm = 760mmHg
= 760torr
= 101325Pa
= 101325Nm⁻²
1mmHg = 1torr
1Pa = 1Nm⁻²
101.325 kPa and 101,325 Pa are the same
1000Pa = 1kPa
101,325 Pa and 1 atm
1atm and 101.325 kPa
1. HNO₃ nitric acid
Al(NO₃)₃ aluminium nitrate
You may find the the attached picture the graphical representation of both compounds.
2. You may find bellow the full equations
Explanation:
1. HNO₃ nitric acid, Al(NO₃)₃ aluminium nitrate
dissociation equation
HNO₃ (l) + H₂O (l) → NO₃⁻ (aq) + H₃O⁺ (aq)
Al(NO₃)₃ (s) + H₂O (l) → Al³⁺ (aq) + 3 NO₃⁻ (aq)
2. molecular equations
Al(OH)₃ (s) + NaOH (aq) → NaAl(OH)₄ (s)
Ba(OH)₂ (aq) + NiCl₂ (aq) → BaCl₂ (aq) + Ni(OH)₂ (s)
ionic equations
Al(OH)₃ (s) + Na⁺ (aq) + OH⁻ (aq) → NaAl(OH)₄ (s)
Ba²⁺ (aq) + 2 OH⁻ (aq) + Ni²⁺ (aq) + 2 Cl⁻ (aq) → Ba²⁺ (aq) + 2 Cl⁻ (aq) + Ni(OH)₂ (s)
