Answer:
Explanation:
The energy required to heat water from its fussion point to its boiling point is the sum of latent and sensible heat. That is to say:
chlorine <span>releases more energy than sulfur when an electron is added to its valence energy level.</span>
<span>Endothermic Reaction. This reaction or process absorbs energy from its surroundings, mostly, but will not always be, in form of heat. A reaction that requires the input of energy that breaks a bond will always be endothermic. Best examples of endothermic reaction are: 1) melting cubes; 2) evaporating of liquid; 3) melting solid salts, etc.</span>
Mass of lead Pb = 4.00 g (given)
Density of lead= 11.34 g/mL (given)
When lead is placed in a graduated cylinder which is partially filled with water, the volume of lead will be the volume of water displaced by it.
Density (d) of a substance is the ratio of mass (m) to the volume (m) of the substance.
The formula of density is given as:
Putting the given values of density and mass of lead, we get
Rearrange the equation, to find the volume
Therefore, volume replaced by lead is 0.353 mL
Answer: Density is a measure of mass per volume. The average density of an object equals its total mass divided by its total volume.
