WILL GIVE THE BRAIN THING- Complete the following single replacement reaction.

Al(s) + HNO3(aq)

What are the products before balancing

The products are Al(NO₃)₃(aq) and H₂(g).

Al(s) + 3 HNO₃(aq) ⇒ Al(NO₃)₃(aq) + 1.5 H₂(g)

Explanation:

Let's consider the reaction between aluminum and nitric acid. This is a single replacement reaction, in which Al replaces H in HNO₃ to form aluminum nitrate. The unbalanced reaction is:

Al(s) + HNO₃(aq) ⇒ Al(NO₃)₃(aq) + H₂(g)

We start balancing N atoms by multiplying HNO₃ by 3.

Al(s) + 3 HNO₃(aq) ⇒ Al(NO₃)₃(aq) + H₂(g)

Finally, we get the balanced equation multiplying H₂ by 1.5.

Al(s) + 3 HNO₃(aq) ⇒ Al(NO₃)₃(aq) + 1.5 H₂(g)

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
