Answer:
There are 110 elements known to us, out of which 92 are naturally occurring, while the rest have been prepared artificially. Elements are further classified into metals, non-metals, and metalloids..

Answer:
Partial pressure of ammonia is 0,28.
Explanation:
For the reaction:
NH₄HS(s) ⇄ NH₃(g) + H₂S(g)
kp = 0,080 is defined as:
0,080 = P[NH₃] P[H₂S] <em>(1)</em>
Where P[NH₃] is partial pressure of NH₃
Asuming amount of NH₄HS is 1, equilibrium concentration for each compound is:
[NH₄HS] = 1 - x
P [NH₃] = x
P [H₂S] = x
Replacing in (1):
0,080 = X×X
0,080 = X²
X = 0,28 = P[NH₃]
I hope it helps
Explanation: • Electronegativity is the tendency of an atom to attract the electrons in a bond towards it. • Ionization energy is the energy that should be given to a neutral atom to remove an electron from it. The difference in the electronegativity between the two elements is quite small, but the main reason for it is because chlorine is one period below oxygen. Chlorine’s valence electrons are thus less tightly bound than those of oxygen, so they would have lower first ionization energy. Does sodium or potassium have larger ionization energy?
A characteristic of strong base is that
<span>It removes H+ ions from solution.

A strong base can dissociate into ions that can react with an acid resulting to the removal of H+ ions from a solution. A weak base only dissociates partially which removes less H+ ions in a solution.
