Explanation: Temperature Affects Density
When the same amount of water is heated or cooled, its density changes. When the water is heated, it expands, increasing in volume. ... The warmer the water, the more space it takes up, and the lower its density.
Answer:
Polar molecules typically do not conduct electricity as well as ionic molecules. This is because charges in polar molecules due to unequal sharing of electrons are not as strong as the charges on ions
10.045830 × atoms of scandium are in 75.0 g.
<h3>What are moles?</h3>
A mole is defined as 6.02214076 × of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
Given data:
Mass of scandium = 7
Molar mass of scandium=44.96 g/mol
Moles =1.66814 moles
Number of atom= 1.66814 moles x 6.02214076 ×
Hence, 10.045830 × atoms of scandium are in 75.0 g.
