Methylene chloride is less dense than water
Blood is pumped throughout the body by your heart. Your heart is the main organ responsible for blood circulation.
Answer is: density of the substance, energy of the substance, intermolecular bonds between particles.
Melting is a physical change (process), the same substance is present before and after the change, so chemical bonds and melting point of the substance are not changed.
Density of liquids are usually less than in solids, because atoms are further apart.
Liquids have higher energy and atoms or molecules move faster.
Intermolecular bonds are weaker in liquids.
Answer:
d = 3.29 g/cm³
Explanation:
Given data:
Density of material = ?
Mass of material = 56.6 g
Volume of material = 17.2 cm³
Solution:
Formula;
d = m/v
d = density
m = mass
v = volume
by putting values,
d = 56.6 g/ 17.2 cm³
d = 3.29 g/cm³
You need to follow the atomic radius trend, the atomic radius decreases as you go across the period, and the atomic radius increases as you go down a group.
Between Sodium, Magnesium, Aluminum, silicon, and phosphorus, Sodium has the biggest atomic radius.
