Answer:
Explanation:
Using the ideal gas equation as follows:
PV = nRT
Where:
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
Based on the information provided in this question;
P = 1.6atm
n = 4.4 moles
R = 0.0821 L*atm/mol*K
T = 32.9°C = 32.9 + 273 = 305.9K
V = ?
Answer: 1.284M NH3
Explanation: (12.23 grams)/(17.0 gramms/mole) = 0.7191 moles
Dissolved in 560.0 ml (=0.5600L)
(0.7191 moles)/(0.560L) = 1.284M (4 sig figs)
Answer:
4Hg+2O2=4HgO
four Mercury + four oxygen
Answer:
Gravitation, Potential and Kinetic Energy, Acceleration
Explanation:
Gravitation: is the force by which object is drawn towards the earth center, its so fundamental to roller coasters when in motion. As it disengages from the initial chain lift otherwise called propulsion force, gravity ensures movement along its track pushing riders forward and backwards in their seats
Potential and Kinetic Energy: The changes in a roller coaster's speed and height is determined by these energy, the higher an object is off the ground, the more ability to gain speed as it falls (meaning more potential energy). As it falls back to the ground, the potential energy changes to kinetic energy thus ensuring motion is continued.
Acceleration: these is a change in speed or direction, thereby a roller coaster can accelerate through bends and curves when speed is constant or changed
