The last photo because its molecular formula is C3H4.
Explanation:
an ion is an atom with a met electric charge due to the loss or gain of one or more electrons and an isotope can be in 2 forms of the same element that contain equal numbers of protons but a different numbers of neutrons in their nuclei and hence differ in relative atomic mass but not in chemical properties
Answer:
Kp=Kc *(RT)+-3
Explanation:
The relation between Kp and Kc is given below:
Where,
Kp is the pressure equilibrium constant
Kc is the molar equilibrium constant
R is gas constant , R = 0.082057 L atm.mol⁻¹K⁻¹
T is the temperature in Kelvins
Δn = (No. of moles of gaseous products)-(No. of moles of gaseous reactants)
For the first equilibrium reaction:
Δn = (0)-(2+1) = -3
Thus, Kp is:
Kp=Kc *(RT)+-3
Answer:
B. 16
Explanation:
Cl -35 and Cl-33 have the same number of protons because it is the same element Cl.
Their masses are different because they have different number of neutrons.
Cl- 33 has 2 neutrons less than Cl-35.
35 - 33 = 2
If Cl-35 has 18 neutrons, then Cl-33 has 18-2=16 neutrons.
I need more points but I think it is 84737
