Which substance is a base? HCOOH RbOH H2CO3 NaNO3

Alex Ar [27]

Answer:

RbOH

Explanation:

For this question, we have to remember what is the definition of a base. A base is a compound that has the <u>ability to produce hydroxyl ions</u> $OH^-$ , so:

$AOH~->~A^+~+~OH^-$

With this in mind we can write the <u>reaction for each substance:</u>

$HCOOH~->~HCOO^-~+~H^+$

$RbOH~->~Rb^+~+~OH^-$

$H_2CO_3~->~CO_3^-^2~+~2H^+$

$NaNO_3~->~Na^+~+~NO_3^-$

The only compound that fits with the definition is $RbOH$ , so this is our <u>base</u>.

I hope it helps!

Ozone has a molecular formula of O3. If 7.92*1024 atoms of oxygen react to form ozone, how many

prisoha [69]

337.92 moles of Ozone will be produced

1 Oxygen atom is 8 g

1 mole of ozone, O3 = 8 * 3 = 24 g

7.92 * 1024 = 8110.08 g

1 mole = 24 g

? moles = 8110.08 g

? = 337.92 moles
