NaHCO3 +HCI —> NaCI+CO2 +H2O 4. What was the actual yield of NaCl from your reaction?

5. In this lab, HCI was the excess reactant and NaHCO, was the limiting reactant.

Using the data you collected and the balanced chemical equation you wrote,
calculate the theoretical yield for Naci. (this is a gramsA to grams
conversion)

6. What was the percent yield of your reaction?

where's the diagram?

i just learnt this recently but i need to look through my notes again

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
