Not Sure Let Me Review My Answer I Know I have Done This One Before Hmm!
I am homeschooled! ive been homeschooled for almost a year and im in 8th grade
Answer:
∆S = ∆H / T = 17.2 kJ/mol (298 K)
∆S = 0.0577 kJ/mol K
∆S = 0.0577 kJ/mol K x 1.41 moles = 0.0814 kJ/K = 81.4 J/K
1.41 mol x 17.2 kJ/mol = 24.25 kJ
∆S = 24.25 kJ / 298 K = 0.0814 kJ/K = 81.4 J/K

1400000 cm
Explanation:
14 km equals to 1400000 cm (14 km = 1400000 cm)
PLEASE MARK ME AS THE BRAINLIEST... ;)
Answer:
The formulas that will be used are:
Situation one:
The moon will be experiencing gravitational force in the form of centripetal force, so we equate the two formulas.
Gravitational force = GMm /r²
Centripetal force = mv²/r
Equating,
GMm/r² = mv²/r
v² = GM/r
The first scenario will use the formula v² = GM/r
Situation 2:
The second situation will use the simple distance over time formula for velocity, where the distance will be the circumference and the time will be in seconds.
v = 2rπ/t
