Heat is energy, and that energy would eventually cause the object to undergo a phase change.
Na2C03 is formed through the reaction of
NaOH and H2CO3 namely sodium hydroxide and carbonic acid
NaOH -> strong base
H2CO3-> weak acid
It is know as the normal force.
When a solid is placed on a support, the latter exerts forces on the solid at each point of contact. These are forces that oppose the weight and prevent an object from falling.
This force is usually vertical and upward and often offsets the weight. If the solid is in equilibrium on the support the forces compensate the weight of the solid.
Iodine is going to form anions capturing electrons from some other element more electropositive
Answer:
Mass of sample is 99.9 g, density of ample is 11.35
and temperature of sample is 
Explanation:
Mass is an additive property. Therefore mass of combined sample is summation of masses of two pellets.
Mass of combined sample = (37.2+62.7) g = 99.9 g
Density is an intensive property. Therefore density of combined sample of lead will be same as with density of Pb.
Density of combined sample = 11.35 
Temperature is an intensive property. Therefore temperature of combined sample of lead will be same as with individual pellets.
temperature of combined sample =
