Answer:
a) 0.2118 mol of I₂ is produced.
b) 49.93 g of I₂ is produced.
Explanation:
a) The balanced equation shows that to produce 1 mol of I₂ we need 2 mol of CuCl₂ . Therefore, the amount of I₂ produced will always be half the amount of CuCl₂ given.
b) In order to calculate the mass of I₂ produced we need to know its molar mass:
Each mole of I₂ weighs 253.8 g, therefore MM = 253.8 g/mol.
Answer:
Magnesium oxide is a type of magnesium mineral supplement that is mostly made of magnesium—it actually contains more magnesium than other magnesium supplements. Magnesium oxide is acquired by burning magnesium with pure oxygen, but this method is quite costly.

Answer: 1.788 volts.
Explanation:
To solve this problem we can combine battery cells to create higher voltages. Building more lemon batteries and connecting them with a metal wire from "+" to "-" adds the voltage from each cell. The two lemon batteries above, combine to produce a voltage of 1.788 volts.
Answer:
New temp = 135°C
Explanation:
From ideal gas equation
But; P1 = 10000Pa. P2 = 45000
V1 = 200 cc. V2 = 100 cc
T1 = 60°C. T2 = ??
From our formulae above
then T2= 45000×100×60÷ (10000×200)
T2= 135°C
