Answer:
Hey mate.....
Explanation:
This is your answer,
Living things differ from non living things through motion, action, expression, way of living and etc......
Livings things:-
1. Livings things means something that keeps on moving or doing any particular work.
2. Livings things mostly consume, remove, and reproduce through different ways.
3. Examples of livings things are humans, animals, birds, reptiles, and even the germs like bacteria, fungi, ameoba and etc....
Non Livings things:-
1. Non Living things means something that just stays like a statue usually and never move or do a particular work.
2. Non living things do not consume, remove or reproduce anything.
3. Examples of non living things are table, chair, fan, house, book etc....
hope it helps you mate....

Answer:
solubility is 1.984x10⁻⁹M
Explanation:
When CaCO₃ is in water, the equilibrium that occurs is:
CaCO₃(s) ⇄ Ca²⁺(aq) + CO₃²⁻(aq)
Kps = [Ca²⁺] [CO₃²⁻] = 4.96x10⁻⁹
If you have a 0.250M solution of Na₂CO₃, [CO₃²⁻] = 0.250M:
[Ca²⁺] [0.250M] = 4.96x10⁻⁹
Assuming you are adding an amount of CaCO₃:
[X] [0.250 + X] = 4.96x10⁻⁹
<em>Where X is the amoun of CaCO₃ you can add, that means, solubility</em>
X² + 0.250X - 4.96x10⁻⁹ = 0
Solving for X:
X = -0.25M → False answer, there is no negative concentrations.
X = 1.984x10⁻⁹M.
That means, <em>solubility is 1.984x10⁻⁹M</em>
Proton number = the atomic number (which is the smaller number
neutron number = the mass number (the bigger number) - the atomic number
number of electrons = the atomic number - the charge (it depends on the element but group 1 is +1 group 2 is +2 group 3 is +3 group five is -3 group six is -2 group seven is -1
i would solve the whole thing but its unclear hope this helps tho
Answer:
<h3>The answer is kinetic energy</h3>
Explanation:
<h2>The answer is Kinetic Energy because take for an example, When an apple falls from the tree to the ground, its energy of position is then made into kinetic energy, the energy of motion, as it falls to the ground. </h2>
