Hey there !
a) Pb(SO4)2 => <span> lead(II) sulfate
b) </span><span>The molar mass of this compound was calculated from the amount of atoms of each element, with its respective atomic masses
Pb = 207.2 a.m.u
S = 32.065 a.m.u
O = </span><span>15.9994 a.m.u
Therefore:
</span>Pb(SO4)2 = 207.2 + 32.065 * 2 + 15.9994 * 8 => <span>399.3252 g/mol
</span>
hope this helps!
The given statement is true, because the activation energy must be provided in order for the molecule to reach the transition state because it is a high-energy state. Reactant molecules don't stay in the transition state for very long since it is unstable; instead, they move on to the next phase of the chemical reaction right away.
To create a successful transition state (with lower activation energy). Heat, which is the most frequently employed energy source, favours the breakdown of processes and lowers the amount of energy needed when the enzyme attaches to the substrate.
The remainder of the process can be completed once the molecule has taken in enough energy to reach the transition state.

Answer:
Explanation:
From the information above:
The equation for the reactor volume of CSTR is given by the formula:
The reaction rate of A is:
and k = 3 dm³/mol.h
replacing the values in the above equation to solve for v;
∴
V = 66,000 dm³
Thus, the reactor volume of CSTR is 66000 dm³
Taking the differential mole balance equation for PFR is as follows:
Taking the integral between initial and final concentrations;
replace the values in the above equation;
Thus, the reactor volume of PFR is 660 dm³
Answer:
The molar mass and molecular weight of 3CaCl2 is 332.952.
Answer:
The valence shell has higher energy than other occupied shells
Explanation:
According to Bohr's model of the atom, he suggested that the extranuclear part consists of electrons in specific spherical orbits around the nucleus.
His model suggests that the electron can move round the nucleus in certain permissible orbits or energy levels. The ground state is the lowest energy state available to the electron. The excited state is any level higher than the ground state.
The valence electrons are in the outermost shell of an atom. These electrons are of the highest energy levels in the atom
