Answer:
d ≈ 0.098 g/mL
Explanation:
The density of a substance can be found by dividing the mass by the volume.
d=m/v
The mass of the substance is 0.221 grams and the volume is 2.25 milliliters.
m= 0.221 g
v= 2.25 mL
Substitute the values into the formula.
d= 0.221 g / 2.25 mL
Divide
d= 0.098222222 g/mL
Let’s round to the nearest thousandth. The 2 in the ten thousandths tells us to keep the 8 in the thousandth place.
d ≈ 0.098 g/mL
The density of the substance is about 0.098 grams per milliliter.
Answer:
The melting and boiling points of molecular compounds are generally quite low compared to those of ionic compounds. This is because the energy required to disrupt the intermolecular forces between molecules is far less than the energy required to break the ionic bonds in a crystalline ionic compound (Figure 6.2. 1) .
Explanation:
hopefully this helps :)
if not then here. (Most of the time, the melting points of ionic compounds are very high compared to the melting points of molecular compounds.)
Omg I wish I knew this one sorry
Hope you can figure it out
Answer: 6 mol Li
Explanation:
The first step is to balance the equation.
2Li+Cl₂⇒2LiCl
We would need our conversions to find the amount of moles of Li needed to produces 6 mol LiCl.
