The girl should first prevent getting scammed. She shouldn’t be sharing any personal information about herself or anybody else. Then to try to prove, she can maybe ask to face time during the day, or asks him out to go somewhere(park,movies,etc.,) but make sure you take someone with you like a trusted adult or someone older, and if he keeps making excuses and denying then it’s pretty clear it’s a catfish.
Answer:
Re=309926.13
Explanation:
density=92.8lbm/ft3*(0.45kg/1lbm)*(1ft3/0.028m3)=1491.43kg/m3
viscosity=4.1cP*((1*10-3kg/m*s)/1cP)=0.0041kg/m*s
velocity=237ft/min*(1min/60s)*(0.3048m/1ft)=1.2m/s
diameter=28inch*(0.0254m/1inch)=0.71m
Re=(density*velocity*diameter)/viscosity=(1491.43kg/m3*1.2m/s*0.71m)/0.0041kg/m*s
Re=309926.13
Answer: 24 moles of
are produced.
Explanation:
To calculate the moles :

According to stoichiometry :
1 mole of
is accompanied with = 1 mole of 
Thus 24 moles of
is accompanied with =
of 
Thus 24 moles of
are produced.
Answer:
46
Explanation:
Sodium metal has a molar mass of
22.99
The answer is C. 146g because you add all of the masses of the individual elements and then mulyiply by 1.72 to get your answer.
