Answer:
0.30 mole NaCl needed.
Explanation:
From the definition of solution molarity => Molarity = moles solute / Volume of Solution in Liters => Molarity = moles/Volume(L) => solve for moles =>
moles = Molarity X Volume(L) = (0.1M)(3.0L) = 0.30 mole NaCl needed.
Inorganic chemistry studies the chemical compounds in inorganic, or non-living things such as minerals and metals.
Explanation:
The standard entropy change of a reaction has a positive value. This reaction results in an increase in entropy.
Positive entropy means the system has increased its degree of disorderness.
Answer:
750mmHg
Explanation:
The following data were obtained from the question:
T1 = 127°C = 127 +273 = 400K
T2 = 27°C = 27 +273 = 300K
P1 = 1000mmHg
P2 =?
P1/T1 = P2/T2
1000/400 = P2 /300
Cross multiply
400 x P2 = 1000 x 300
Divide both side by 400
P2 = (1000 x 300)/400
P2 = 750mmHg
Therefore, the new pressure after cooling is 750mmHg
Al2(SO4)3 would be the formula.
