Answer:
Reactants
Explanation:
In a chemical reaction, reactants must react to form products, so products are equal to the reactants
Density is calculated using the following rule:
density = mass / volume
therefore:
mass = density * volume
mass of Hg = 13.6 * 60.2 = 818.72 grams
From the periodic table:
molar mass of Hg = 200.59 grams
number of moles = mass / molar mass
number of moles of Hg = 818.72 / 200.59 = 4.08 moles
each mole contains Avogadro's number of atoms.
Therefore,
number of atoms in the given sample = 4.08 * 6.022 * 10^23
= 2.456976 * 10^24 atoms
Option no. 2 subtracting the atomic number from the mass number
Example: Zn - 65 atomic weight or mass/mass number
30 atomic number
65-30 = 35 number of neutrons
Answer:
If you are creating the reaction, then you would agitate the particles to cause them to become more active.
Explanation:
This can be done by stirring them, heating them up, or by swirling the container.
<h2><em>Solid. Because molecules densely packed it has a high resistance to flow thereby lower kinetic energy.
