Is it possible to tell if an acid or base is strong or weak just by looking at its chemical formula?

It is.

An acid will be strong when its conjugated base is highly stable, and vice-versa.

That can occur for instance through electronic delocalization.

Consider the reaction h2(g) + cl2(g) ⇀↽ 2 hcl(g), which is exothermic as written. what would be the effect on the equilibrium po
kupik [55]
I think the effect of increasing temperature would be; the equilbrium will shift back wards. Increase in temperature favors backward reaction since the forward reaction is exothermic and the backward reaction is endothermic. Therefore, the equilibrium will shift back wards, and there will be more reactants (H2 and Cl2) compared to the products

Answer:

1= Magnesium

2 = Option 3 =  1s² 2s² 2p⁶

Explanation:

An electrically neutral atom consist of equal number of protons and electrons.

The answer for 1st q is magnesium because the electronic configuration showed twelve number of electrons. The atomic number of magnesium is twelve that's why this configuration is of Mg.

Mg₁₂ =  1s² 2s² 2p⁶ 3s²

The second answer is option three because has atomic number ten and third electronic configuration have ten electrons.

Ne₁₀ = 1s² 2s² 2p⁶

It is stable electronic configuration. Neon is inert because of this electronic configuration. The outer most shell is completely filled.

2.5 moles of sodium chloride is dissolved to make 0.050 liters of solution
Hitman42 [59]

The answer is:

the molarity = 50 moles/liters

The explanation:

when the molarity is = the number of moles / volume per liters.

and when the number of moles =2.5 moles

and the volume per liters = 0.05 L

so by substitution:

the molarity = 2.5moles/0.05L

                    = 50 moles /L
