It is made of the same compounds and molecular build as our sun but is 216x bigger and has about the same amount of mass
Answer:
The correct answer is 0.12 grams.
Explanation:
The mass of carbon monoxide or CO collected in the tube can be determined by using the ideal gas equation, that is, PV = nRT.
Based on the given question, P or the pressure of the gas is given as 1 atm, volume of the gas collected in the tube is 117 ml or 0.117 L.
The number of moles or n can be determined by using the equation, mass/molar mass.
R is the universal gas constant, whose value is 0.0821 L atmK^-1mol^-1, and temperature is 55 degree C or 328 K (55+273).
On putting the values we get:
n = PV/RT
= (1 atm*0.117 L) / (0.0821 L atmK^-1mol^-1 * 328 K)
= 0.0043447 mol
Therefore, mass of CO will be moles * molar mass of CO
= 0.0043447 mol * 28 g/mol
= 0.12 g
Answer:
0.246M
Explanation:
0.123M x 2 = 0.246M
Due to Sr(OH)2 has the coefficient of 2.
The rock cycle
The rock cycle can have sedimentary, igneous, or metamorphic rocks going back and forth changing into different rocks.
Answer:
I disagree, because earth rotation on its axis causes day and night, on the other hand the its revolution on the orbit around the sun causes seasons. One Rotation would means one day has completed, and one revolution would mean that one year has completed. Therefore, it's obvious that Earth's revolution takes longer than the rotation.
I hope that helps...
