Answer:
A: The bonds of a Molecule
Explanation:
Density = mass / volume
9.51 = m / 9.26
9.51 * 9.26 = m
m = 88.0626
<h2>Answer:</h2>
<em>Third option is correct, 7.5 grams of CuI.</em>
<h3>Explanation:</h3>
Given data :
Mass of copper = 10 grams
Mass of iodine = 10 grams
theoretical yield of copper iodide = ?
Solution:
Moles of Cu: 10 / 63.5 = 0.157 mol.
Moles of I2: 10 / 254 = 0.039 mol.
Equation : 2Cu + I2 → 2CuI
Limiting reactant : I2
So Moles of CuI produced = 0.039 mol.
Mass of CuI = 0.039 mol * 190.5 = around 7.5g
Answer:
The three major types of intermolecular interactions are dipole–dipole interactions, London dispersion forces (these two are often referred to collectively as van der Waals forces), and hydrogen bonds.
