3024.75 Joules needed to warm iron
Answer:
will be 90054 J
Explanation:
Number of moles = (mass)/(molar mass)
Molar mass of
= 134.45 g/mol
So, 1.00 g of
=
of
= 0.00744 mol of 
0.00744 mol of
produces 670 J of heat
So, 1 mol of
produces
of heat or 90054 J of heat
Answer:
Explanation:
There is a formula for this:
M = DRT/P where M = molar mass. This just derived from PV = nRT where you say n = grams/molar mass. However, just with this formula, we can get D which is density at STP (1 atm and 273K). We find that D = 6.52g/L.
Answer:
domain bacteria
Explanation:
Salmonella and E. coli are same in the sense that they are both bacteria,
Answer:
2cm^3
Explanation:
Use the density triangle: D=MxV
Switch for variables, V=M/D
Plug in numbers, 15.8g/7.9g/cm^3=2cm^3
