Because if an electron was in an atom, it would allow two atoms to combine without exploding and disentigrating, therfore there would be no suck thing as nuclear fission (nuclear bomb)
Answer: The answer is Yes, because they were formed from the remains of plants and animals from millions of years ago.
The correct answer is Ozone.
Ozone, sometimes known as O3, is a poisonous and unstable gas. Ozone is a potent allotrope of oxygen; it absorbs heat when it is present in large quantities all over the earth. A molecule called ozone has three oxygen atoms in it. At ground level, it is dangerous and unstable. O3 O3's efficacy in treating infections, wounds, and several disorders has been extensively established. Before the turn of the century, it was employed to sterilize drinking water. One study found that ozone could cure 114 different ailments. Headaches, coughing, a dry throat, difficulty breathing, a heavy feeling in the chest, and fluid in the lungs can all be side effects of ozone exposure.

The answer is D, the attractive force between them decreases.
Although the volume that the particles take up generally increases when going from solid to liquid, particles themselves never change their size. It’s the attractive force that decreases and doesn’t pull the particles together as tightly when a solid changes to liquid.
The balanced equation for the reaction between Ba(OH)₂ and HCl is as follows;
Ba(OH)₂ + 2HCl ---> BaCl₂ + 2H₂O
stoichiometry of Ba(OH)₂ to HCl is 1:2
the number of HCl moles that have reacted - 0.2452 mol/L x (20.00 x 10⁻³ L)
number of HCl moles reacted = 0.004904 mol
2 mol of HCl reacts with 1 mol of Ba(OH)₂
therefore 0.004904 mol of HCl reacts with - 1/2 x 0.004904 mol of Ba(OH)₂
number of Ba(OH)₂ moles in 18.15 mL - 0.002452 mol
Therefore number of Ba(OH)₂ moles in 1000 mL- 0.002452 mol /(18.15 x 10⁻³ L)
molarity of Ba(OH)₂ is = 0.1351 M
