The visible constellations<span> are definitely different
between the Northern and Southern Hemispheres. In general, at any given point
on Earth, only around 50% of the sky will be visible. We can understand this by
considering the atmosphere as a sphere around the earth. The sky any person can
view at one point can be compared to a giant dome equal to half of the sphere.
And because the Earth rotates, the dome we can see changes, unless one is
sitting directly on the North or South Pole.</span>
Answer:
The correct answer is 169.56 g/mol.
Explanation:
Based on the given information, the mass of Ag deposited is 1.24 g, and the mass of unknown metal X deposited in another cell is 0.650 g. The number of moles of electrons can be determined as,
= 1.24 g Ag * 1mol Ag/107.87 g/mol Ag * 1 mol electron/1 mol Ag ( the molecular mass of Ag is 107.87 g/mol)
= 0.0115 mole of electron
The half cell reaction for the metal X is,
X^3+ (aq) + 3e- = X (s)
From the reaction, it came out that 3 faraday will reduce one mole of X^3+.
The molar mass of X will be,
= 0.650 g/0.0115 *3 mol electron/1 mol
= 56.52 * 3
= 169.56 g/mol
