Beacause of lack of force in all three scenarios.
In scenario one there’s two forces acting in the bottle atmospheric pressure and gravity.Gravity keeps the ball at the lowest pointwithout force resisting it.
Umber two there’s no other force greater than gravity that would cause movement to the apple..
And number three there are isn’t any force acting in the rubber band greater than the elastic force to make it stretch
Hope this helps and mark as brainliest if you thought it was most helpful :)
Osmosis is the diffusion of water from a high concentration to a lower concentration
Answer:
Al + HCl → AlCl₃ + H₂
Its single displacement reaction.
Explanation:
Chemical equation:
2NH₄NO₃ → 2N₂ + 4H₂O + O₂
It is the decomposition reaction in which ammonium nitrate decompose to give nitrogen , water and oxygen.
Chemical equation:
2H₂O₂ → 2H₂O + O₂
It is the decomposition reaction in which hydrogen peroxide decompose to give water and oxygen.
Chemical equation:
2KCl → 2K + Cl₂
It is the decomposition reaction in which potassium chloride decompose to give its constituent elements potassium and chlorine.
Chemical equation:
2Al +6 HCl → 2AlCl₃ +3 H₂
This is single replacement reaction in which aluminium react with HCl and form aluminium chloride and hydrogen.
Answer:
A:Boyle's Law or B:Charles's Law
Explanation:
The principal quantum number, <span>nn</span>, designates the principal electron shell. Because n describes the most probable distance of the electrons from the nucleus, the larger the number n is, the farther the electron is from the nucleus, the larger the size of the orbital, and the larger the atom is. n can be any positive integer starting at 1, as <span><span>n=1</span><span>n=1</span></span> designates the first principal shell (the innermost shell). The first principal shell is also called the ground state, or lowest energy state. This explains why <span>nn</span> can not be 0 or any negative integer, because there exists no atoms with zero or a negative amount of energy levels/principal shells. When an electron is in an excited state or it gains energy, it may jump to the second principle shell, where <span><span>n=2</span><span>n=2</span></span>. This is called absorption because the electron is "absorbing" photons, or energy. Known as emission, electrons can also "emit" energy as they jump to lower principle shells, where n decreases by whole numbers. As the energy of the electron increases, so does the principal quantum number, e.g., n = 3 indicates the third principal shell, n = 4 indicates the fourth principal shell, and so on.
