Answer:
0.090 J/(mmol·°C) × (1000 mmol/mole × 1 kJ/(1000 J)) = 0.090 kJ/mole
Explanation:
The unit of conversion from kilo-Joules to Joules is given as follows;
1000 Joules = 1 kilo-Joule
The unit of conversion from milimoles to moles is given as follows;
1000 milimoles = 1 Mole
Therefore, we have
The value of the given expression is 0.090 J/(mmol·°C) × 1000 mmol/mole × 1 kJ/(1000 J) = 0.090 kJ/mole
0.090 J/milimole = 0.09 kJ/mole.
Answer:
A. a magnet
Explanation:
Iron fillings could be separated from sand using a magnet
Explanation:
nso3=75/80 (80=Mr of so3)
n of o= 75x3/80
x of o= 75x3/80x6.02x10 powered by 23
then, the anwer is
sry if im wrong
B) A chemical change because the nail reacts with water/oxygen to create rust (a type of oxide)
