Answer:
Case 1 (energy level): In an atom, an electron jumps from energy level 1 to energy level 3. ... The energy will increase.
Explanation:
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
Explanation:
The equation of the reaction is given as;
6CO2 + 6H2O → C6H12O6 + 6O2
How many molecules of CO2 are present?
6 moles
How many atoms of oxygen are present in the reactants?
(6 * 2) + (6 * 1 ) = 12 + 6 = 18
How many atoms of carbon are present in the products?
(6 * 1 ) = 6
How many total atoms are present in C6H12O6?
6 + 12 + 6 = 24 atoms
Is the equation above balanced or unbalanced?
This is a balanced equation since the number of atoms of the elements is the same in the reactant and products.
There you go try that out.
but where Is the volume in order for us to determine the concentration. since we have moles in H+ ions
then you can say
concentration = M*1000/V
