Answer:
A) , ,
A = 1.5×, A = 1.9×, A=1.5×
B) 4.469
Explanation:
From Arrhenius equation
where; K = Rate of constant
A = Pre exponetial factor
= Activation Energy
R = Universal constant
T = Temperature in Kelvin
Given parameters:
taking logarithm on both sides of the equation we have;
since we have the rate of two different temperature the equation can be derived as:
= 19846.04×7.544× = 1.497
= = 4.469
I am sorry can you explain it more?
Answer:
The symbol for an atom indicates the element via its usual two letter symbol, the mass number as a left superscript, the atomic number as a left subscript (sometimes omitted), and the charge as a right superscript.

I hope that helps!! sorry if it dont!
Answer:
0.38 mol
Explanation:
Given data:
Number of formula units = 2.3×10²³
Number of moles = ?
Solution:
According to Avogadro number ,
1 mole contain 6.022×10²³ formula units.
2.3×10²³ formula units × 1 mol / 6.022×10²³ formula units
0.38 mol
Thus, 2.3×10²³ formula units of NaCl contain 0.38 moles of NaCl.
