Alkali metals react with water to produces what product?

Answers

Answer 1
Answer:

Answer:

  • Alkali metals react with water to produce hydroxide and hydrogen gas.

Explanation:

That is a chemical property of alkali metals: they are highly reactive and react vigorously with water to produce the correspondant hydroxide and hydrogen gas.

These are some of those reactions:

  • 2Li (s) + 2H₂O (l)  → 2LiOH (aq) + H₂(g) ↑

  • 2Na (s) + 2H₂O (l)  → 2NaOH (aq) + H₂(g) ↑

  • 2K (s) + 2H₂O (l)  → 2KOH (aq) + H₂(g) ↑

The alkali metals are the elements of group 1 of the periodic table: Li, Na, K, Rb, Cs, and Fr. They have one valence electron which may lose easily to form an ion with charge +1.
Answer 2
Answer:

Final answer:

Alkali metals react with water to produce hydrogen gas and a basic solution of the metal hydroxide (for instance, sodium hydroxide when lithium is in the reaction). This reaction signifies the easier oxidation of alkali metals compared to hydrogen.

Explanation:

When alkali metals react with water, they form hydrogen gas and a basic solution of the metal hydroxide. This vigorous reaction reveals that alkali metals are easier to oxidize than is hydrogen. For instance, considering the reaction of lithium with water:

2Li(s) + 2H₂O(l) --> 2NaOH(aq) + H₂(g)

The solid state (s) lithium reacts with liquid water to generate hydrogen gas and the ionic compound sodium hydroxide. This sodium hydroxide, which is a solid in its pure form, promptly dissolves in water.

The same kind of reaction occurs with other alkali metals and also some alkaline earth metals, although beryllium and magnesium are exceptions.

Explanation:

A chunk of silver has a heat capacity if 42.8 j/*c. If the silver has a mass of 181g, calculate the specific heat of sliver.

Answers

From the given question, we know
Heat capacity of the chunk of silver = 42.8 J/c
Mass of the silver = 181 g
Now we also know the formula for determining the specific heat of silver and that is
Specific heat (C) = heat capacity/ mass
                             = (42.8/181) J/gC
                             = 0.24 J/gC
So the specific heat of the silver is 0.24 J/gC.
With the given known facts, it is easily possible to find out the specific gravity of any substance.


When writing an electron configuration for a transition metal, what is the last orbital type to be filled – an s, p, d or f orbital?

Answers

It would be d.

Reason being said...

the electron configuration normally goes like this...

1s2 2s2 2p6 3s2 3p6 4s2....

until you hit the transition metals..remember those have a special rule..

even though you are in the 4 sublevels for the orbitals ... it goes down 1

Making it 3d..(1,2,3,4,5,6,7,8,9,10)

Going on...

at 5s2 then, 4d1, 4d2, 4d3, 4d4, etc..

at 6s2 then, 5d1, 6d2, 6d3, 6d4, etc..

Thus, D orbital is your answer.
