Answer:
Explanation:
The expression for Bohr energy of the hydrogen-like species is:
Where, Z is the atomic number of the element
For, , Z = 2
For lowest energy, n = 1
Thus, Applying the values as:-
Answer : The concentration of SO₂Cl₂ after 720 min will be,
Explanation :
Expression for rate law for first order kinetics is given by:
where,
k = rate constant =
t = time passed by the sample = 720 min
a = initial amount of the reactant =
a - x = amount left after decay process = ?
Now put all the given values in above equation, we get
Therefore, the concentration of SO₂Cl₂ after 720 min will be,
Since according to ideal gas law, PV=nRT and you have 1.2atm, plug in the value for volume but make sure to convert to L instead of mL and convert temperature to Kelvin
Table salt is a compound because Sodium (Na) and Chlorine (Cl) were combined to make a new group.
78 and 78. An atom of the element has 78 electrons and 78 protons.
The atomic number is 78, so the atom has 78 protons (+).
If the atom is neutral, it must contain 78 electrons (-).
