Answer:
m = 8.1 kg
Explanation:
Density of metal ball, d = 8.96 g/cm³
Diameter of ball, d = 12 cm
Radius of ball, r = 6 cm
Density of an object=mass/volume
The metal ball is in the shape of sphere whose volume is given by :
Now using formula,
or
m = 8.1 kg
So, the mass of the metal ball is 8.1 kg.
Answer:
Terms in this set (31) A reaction that involves the transfer of electrons from one molecule to another is referred to as. a redox reaction. During an oxidation reaction, the donor molecule loses an electron and becomes oxidized.

The reason why is because particles are moving faster and possess greater kinetic energy due to the increase in temperature, this causes greater frequency or number of collisions to take place and also allows for a higher likelihood that upon reactant molecules colliding they will undergo the reaction process as they will have achieved the required energy needed for the reaction to start. Thus overall having a greater change in quantity conversion of reactants to products within a shorter period of time, thus increasing the reaction rate.
<span>The half-life of the reaction is ln 2 / k
= ln 2 / (0.0775 s-1)
= 0.693 s / 0.0775
= 8.94 s</span>
An intramolecular force is any force that binds together the atoms making up a molecule or compound, not to be confused with intermolecular forces, which are the forces present between molecules. The subtle difference in the name comes from the Latin roots of English with inter meaning between or among and intra meaning inside. Chemical bonds are considered to be intramolecular forces, for example. These forces are often stronger than intermolecular forces, which are present between atoms or molecules that are not bonded.
