244.4 degrees farenheit. (118 degrees celsius)
Answer:
1.86 m
Explanation:
Step 1: Calculate the mass of solute and solvent in 100 grams of solution
We have a 15.0% by mass solution of MgCl₂ (solute) in H₂O (water). In 100 g of solution, there are 15.0 g of solute and 100.0 g - 15.0 g = 85.0 g of solvent.
Step 2: Calculate the moles corresponding to 15.0 g of MgCl₂
The molar mass of MgCl₂ is 95.21 g/mol.
Step 3: Convert the mass of water to kilograms
We will use the relationship 1 kg = 1,000 g.
Step 4: Calculate the molality of the solution
Answer:
ionic bond
Explanation:
cation calcium looses 2 electrons to bond with two iodine atoms to form CaI2 (Calcium Iodide)
Displacement reaction
Because Al goes to SO4 and
Cu goes from SO4 to Cu
This happens because Al is more reactive (higher up in the reactivity series) than Cu
