CHEMICAL FORMULA - LIMEWATER + HYDROCHLORIC ACID
« on: March 03, 2021, 07:06:03 PM »
To one test-tube add 2 dropper full of limewater and stopper test-tube. To another test-tube add two dropper full of hydrochloric acid and then add a scoop of sodium bicarbonate to the acid until no further change is observed. Pour the gas produced into the limewater, shake and record your observations.

We need to find the formula and the equations.
 
Would this be

Word equations:  Calcium Hydroxide (limewater) (aq) + Hydrochloric Acid (aq) + Sodium Bicarbonate (s) = Sodium Chloride (aq) + Dihydrogen Monoxide (l) + Carbon dioxide (g)

Formula equations: Ca(OH)2 (aq) + HCl (aq) + NaHCO3(aq) = NaCl (aq) + H2O (l) + CO2 (g)

and would there be heat added in the question as we need heat to form the CO2 gas??

and thsi would be a neutralization reaction right?

I wasnt sure about my formuals because this seems wrong to me.

Thank you

It is wrong, where is the calcium left?

Moreover, you have two separate reactions.

Careful with that dihydrogen monoxide; it's dangerous stuff, if you believe the internet!

Of course a lot of people died by drinking to much of it or try to breath in this liquid.

ok so my teacher told me that we would not include limewater in the equations, which is why limewater is not present in the equatiosn

yes, thank you. I realized after clarifying with my teacher that limewater is not included in the actual reaction part of it. so only the other two compounds would be
