Answer: Double Replacement
Explanation: When one of the elements in the compound is replaced by another element. In a single replacement reaction, Minnie Mouse leaves Mickey Mouse for Goofy. This happens when a compound is broken down into separate elements, or the opposite of synthesis.
It may seem a little silly but i hope it helps
Ideal gas law:
pv = nrt
nr is mole times the ideal gas constant, these are both held constant (do not change value)
pv/t = nr
Then you can set the conditions before = after
pv/t = PV/T
before: (convert to Kelvin)
(0.995)(5.27x10^4) / 305
After: (convert to Kelvin)
(0.720)V / 206.3
solve for V , volume after.
(0.995)(5.27x10^4) / 305 = (0.720)V / 206.3
4.926 x 10^4 L = V
Hey there !
Molecular Weight: 262.86 g/mol
Volume in liters : 1,000 mL => 1,000 / 1000 => 1 L
Number of moles of solution :
number of moles = volume x molarity
number of moles = 1 x 0.3 => 0.3 moles
Therefore:
1 mole Mg₃(PO₄)₂ ------------------- 262.86 g
0.3 moles ----------------------------- mass of Mg₃(PO₄)₂ ??
mass of Mg₃(PO₄)₂ = 0.3 x 262.86 / 1
mass of Mg(PO₄)₂ => 78.858 g
Hope this helps!
