Answer: Thus the yield of uranium from 2.50 kg 
is 2.12 kg
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number 
of particles.
To calculate the number of moles, we use the equation:
moles of 
(1kg=1000g)
As 1 mole of contains = 3 moles of U
2.97 mole of contains = 
moles of U
Mass of Uranium=
( 1kg=1000g)
Thus the yield of uranium from 2.50 kg is 2.12 kg
The moles of fluorine present are 71/19 = 3.74
Now, we know that one mole of gas at 273 K and 101.3 kPa (S.T.P.) occupies 22.4 liters
Volume of 3.74 moles at S.T.P = 3.74 x 22.4
Volume = 83.776 L = 83,776 mL
Now, we use Boyle's law, that for a given amount of gas,
PV = constant
P x 6843 = 101.3 x 83776
P = 1,240 kPa
Answer:
Pressure = 0.64 atm
Explanation:
Use Ideal Gas Law PV = nRT => P = nRT/V
n = moles CO₂(g) = 66g/44g/mol = 1.5 mol CO₂
R = Gas Constant = 0.08206 L·atm/mol·K
T = Temperature = -14.5°C = (-14.5 + 273)K = 258.5 K
V = 50.0 Liters
P = (1.5 mol)(0.08206 L·atm/mol·K)(258.5 K)/(50.0 L) = 0.64 atm
Elements in same group / family tend to have similar properties ( but not exactly the same). Since, iron and silver are in two different group / families, they have different properties.
Also, Silver and iron have different properties because they have different atomic structure. Having different atomic structure means bonding differently with other elements. So, they have different properties.
Answer:
The temperature of the solute/solvent without any external effect would decrease.
Explanation:
As the bonding between the solute particles is really strong, therefore a large amount of energy is required to overcome these forces. So that the new bonding between the solute and solvent is created.
In order to achieve this, there will be a lot of energy required and that is through the heating process. So the solution will require energy so the solute will dissolve fully either by provision of external force i.e stirring or by heating.
