Predict whether ΔS for each reaction would be greater than zero, less than zero, or too close to zero to decide: 1. I2(g) + Cl2(g) → 2ICl
2. 2NH3(g) →N2(g) + 3H2(g)
3. CO2(g) + H2(g) → CO(g) + H2O(g)
4. 2CO(g) + 2NO(g) → 2CO2(g) + N2
(g) 5. 2H2O2(l) →2H2O(l) + O2(g)

Answer : option a) 84explanation :

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.

Each calcium ion has a charge of +2, which can also be written as ca2+. if those ions move out of the neuron and no other ions are moving, the neuron would lose the positive charge associated with those ions and become more negatively charged.

The answer is a. stable, hope i ya
