rite stepwise equations for protonation or deprotonation of this polyprotic species in water. What are the products of the first

adoni [48]

<u>Answer:</u> The products of the given chemical equation are $HCO_3^-\text{ and }OH^-$

<u>Explanation:</u>

Protonation equation is defined as the equation in which protons get added in the substance.

The chemical equation for the protonation of carbonate ion in the presence of water follows:

$CO_3^{2-}+H_2O\rightarrow HCO_3^-+OH^-$

By Stoichiometry of the reaction:

1 mole of carbonate ion reacts with 1 mole of water to produce 1 mole of hydrogen carbonate ion and 1 mole of hydroxide ion

Hence, the products of the given chemical equation are $HCO_3^-\text{ and }OH^-$

How many molecules are in 3 moles of NaCl?

PtichkaEL [24]

Answer:

Given : No. Of moles = 1.5

To calculate : no. Of molecules =N

We know that moles = N / 6.022 x 10²³

Therefore, 1.5 x 6.022 x 10²³ = N

Hence N = 9.0330x 10²³ molecules

How many moles are in 1.51 x 10^24 molecules of water?

lyudmila [28]

Answer:One mole of HBr has 6.02 x 1

molecules of HBr.

1 mole of HBr = 6.02 x 1

molecules of HBr.-----(a)

X mole of HBr has 1.21 x

molecules of HBr.

X mole of HBr = 1.21 x

molecules of HBr------(b)

Taking ratio of (a) and (b)

X / 1 = 1.21 x

/ 6.02 x 1

X= 2.009 moles.
