H2so4 + 2naoh --> h2o + na2so4

how many molecules of water are produced if 2.0g of sodium sulfate are produced in the above reaction?

plz i really need : (

2.0 g NaSO4(1 mol NaSO4/142.04 g)(1 mol H2O/1 mol NaSO4)(18.02 g/1 mol H2O)(6.02x10^23 g/ 1 molecule H2O)= 1.5275 molecules of water

They carry out the exchange of gases as we breathe ( oxygen and carbon dioxide).

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
