Answer:
173.8g
Explanation:
STP means standard temperature and pressure
The temperature there is 273k while the pressure is 1 atm
now we are to use the ideal gas equation to get the number of moles first
Mathematically;
PV = nRT
here P = 1 atm
V = 88.5 L
n = ?
R = molar gas constant = 0.082 L atm mol^-1 K^-1
Now rewriting the equation we can have
n = PV/RT
plugging the values we have
n = (1 * 88.5)/(0.082 * 273)
n = 88.5/22.386
n = 3.95 moles
Now we proceed to get the mass
Mathematically;
mass = no of moles * molar mass
molar mass of carbon iv oxide is 44g/mol
mass = 3.95 * 44 = 173.8 g
Answer: the ground state
Explanation: when electron's are attracted to something, they typically rotate counter clockwise, in theory we can apply this to darwin, i recomend that book btw but counter clockwise goes to ground
well its evaporation cuz it the suns heat heated the ice to the point where it turned to a gas, it could be conduction cuz the heat of the sunshine conducted the ice and turned it to a gas but that would be evaporation too so its not onduction, its not a chemical change cuz theres no new molecule the substance is itself, and its not a sudden change obviously
so the answer is A. evaporation~~~
Energy from a light source is known as radiation.
Answer:
Gas is for example oxygen or the air we breath and liquid is water.
