We can use the reactivity series of metals to solve this.

The reactivity series of metals are (in descending order) :
Potassium, sodium, Lithium, calcium, Magnesium, aluminum, zinc, iron, tin, lead, copper, mercury, silver, platinum, gold.

Since Potassium is the most reactive, the reaction with water should produce extremely violent gas.

Sodium is the next most reactive, so it should produce violent gas.

And Lithium is the least reactive out of the 3 metals, so it should be strong gas formation.

In addition, the gas produced should be hydrogen, since the reaction of metals should water should produce "metal name" hydroxide + hydrogen.

Why are we pulled to the center of the Earth and not into the much larger sun?
katrin [286]

Answer:

The sun's gravity pulls on the earth, and the earth pulls back on the sun at the same time. This is why the center of the solar system is not the center of the sun. As one gravitational body gets bigger than the other, it circles closer to the center of the system (shown in red).

hope this helps...

Identify and label the Brønsted-Lowry acid, its conjugate base, the Brønsted-Lowry base, and its conjugate acid in each of the f
julia-pushkina [17]

Explanation:

As per Brønsted-Lowry concept of acids and bases, chemical species which donate proton are called Brønsted-Lowry acids.

The chemical species which accept proton are called Brønsted-Lowry base.

(a) HNO_3 + H_2O \rightarrow H_3O^+ + NO_3^-

HNO_3 is Bronsted lowry acid and NO_3^- is its conjugate base.

H_2O is Bronsted lowry base and H_3O^+ is its conjugate acid.

(b)

CN^- + H_2O \rightarrow HCN + OH^-

CN^- is Bronsted lowry base and HCN is its conjugate acid.

H_2O is Bronsted lowry acid and OH^- is its conjugate base.

(c)

H_2SO_4 + Cl^- \rightarrow HCl + HSO_4^-

H_2SO_4 is Bronsted lowry acid and HSO_4^- is its conjugate base.

Cl^- is Bronsted lowry base and HCl is its conjugate acid.

(d)

HSO_4^-+OH^- \rightarrow SO_4^{2-}+H_2O

HSO_4^- is Bronsted lowry acid and SO_4^{2-} is its conjugate base.

OH^- is Bronsted lowry base and H_2O is its conjugate acid.

(e)

O_{2-}+H_2O \rightarrow 2OH^-

O_{2-} is Bronsted lowry base and OH- is its conjugate acid.

H_2O is Bronsted lowry acid and OH- is its conjugate base.
