The minimum mass of NaHCO3 that must be added to the spill to neutralize the acid is 27.216 grams
<h3>calculation </h3>
write the balanced chemical equation
2NaHCO3 +H2SO4 → Na2SO4 +2H2O +2CO2
find the moles of H2SO4 = molarity x volume in liters
volume in liters = 27/1000=0.027 l
moles is therefore= 0.027 x6=0.162 moles
by use of mole ratio of NaHCO3: H2SO4 which is 2:1 the moles of NaHCO3=0.162 x2=0.324 moles
mass of NaHCO3= moles of NaHCO3 x molar mass of NaHCO3(84g/mol)
= 84g/mol x 0.324=27.216 grams
A metal that would be magnetic is nickel
Para and ortho is actually indicating different name structure of mixture. So if structure is different then boiling/distill/melt temprature will be also different.
Exothermic
Explanation:
A chemical reaction that has ΔH of -2764Kj indicates that the reaction that took place was an exothermic reaction.
- The enthalpy changes accompanying a reaction causes heat changes.
- In an exothermic reaction, heat is usually liberated to the surroundings.
- The environment becomes hotter at the end of the reaction.
- It is assigned a negative value because the sum of the heat contents of products is less than that of reactants.
- A positive sign is for an endothermic reaction.
