Answer:
one mole of atom of any element contains6.022×1033 atoms regardless of the type of elements the mass of one mole of an element depend on what that element is and is equal to atom mass of that element in gram
Answer: 8 moles
Explanation:
Nc2H6= 4 mol
2C2H6 + 7O2 → 4CO2+6H2O
CO2=4/2⋅4
NCO2= 8 moles
( I write this on paper so the letters and format might be confusing) sorry!!
Answer:
The new temperature is 373 K
Explanation:
Step 1: Data given
Volume air = 5000 mL = 5.0 L
Temperature = 223K
New volume = 8.36 L
Step 2: Calculate the new temperature
V1/T1 = V2/T2
⇒V1 = the initial volume = 5.0 L
⇒T1 = the initial temperature = 223 K
⇒V2 = the new volume = 8.36 L
⇒T2 = the new temperature
5.0/223 = 8.36 /T2
T2 = 373 K
The new temperature is 373 K
Answer:
Explanation:
It is volume-volume problems that does not require the use of molar mass.
Answer:
D.
Explanation:
Translation:
A. make a barbecue
B. organize a picnic
C. swimming in the pool
D. to go skiing
Barbecue is usually a summer activity, so we eliminate that.
It would be too cold for a picnic!
It would be too cold to go swimming, and that's more of a summer thing!
Skiing is a snow activity, and since it is winter, it is likely to know.
