Please help:( find the equation

1. Pb(NO3)2 + Na2CO3 → PbCO3 + NaNO3

2. Ca10F2(PO4)6 + H2SO4 → Ca(H2PO4)2 + CaSO4 + HF

3. SiC + Cl2 → SiCl4 + C

4. NaCl + F2 → NaF + Cl2

5.Al + HCl → AlCl3 + H2

6.Ca3(PO4)2 + SiO2 → P4O10 + CaSiO3

7. C2H5OH + O2 → CO2 + H2O

law of conservation of matter

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 :

the population of unionid mussels in the hudson river decreased after zebra mussels were introduced. zebra mussels, a nonnative species, competed with the unionid mussels for food. the zebra mussels were able to outcompete the unionid mussels, allowing the zebra mussel population to increase dramatically over six years. the unionid mussel population decreased due to a lack of food.

hope this :
