We know that sodium is atomic number 11, and it has 11 protons, 11 electrons (in a neutral atom), and will have 12 neutrons in its sodium-23 isotope. Sulfur is atomic number 16, and will have 16 protons, 16 electrons (in a neutral atom), and will have 16 neutrons in it sulfur-32 isotope. Oxygen has atomic number 8, and has 8 protons, 8 electrons (in a neutral atom) and will have 8 neutrons in its oxygen 16 isotope. If we take 2 sodium atoms, a sulfur atom and 4 oxygen atoms, we'll have a total of 70 protons, 72 neutrons and 70 electrons in sum.

What is the concentration of Na2SO4 solution prepared by dissolving 5.35 g of Na2SO4 in sufficient water to give 330 ml of solution?
First.Get moles sodium sulfate.5.35 grams Na2SO4 (1 mole Na2SO4/142.05 grams)= 0.0377 moles Na2SO4-------------------------------------Second.Molarity = moles of solute/Liters of solution ( 330 mL = 0.33 Liters )Molarity = 0.0377 moles Na2SO4/0.33 Liters= 0.114 M Na2SO4=============
How many moles of Na SO4 are in 25.0 of this compound?
25.0 grams Na2SO4 ( only way this compound is possible ) 25.0 grams Na2SO4 (1 mole Na2SO4/142.05 grams) = 0.176 moles Na2SO4 -----------------------------
How many electrons are transferred in the iconic bond between sodium?
Each sodium will transfer 1 electron. So, for NaCl, one electron is transferred. In Na2SO4 (sodium sulfate), 2 electrons will be transferred (1 electron from each sodium).
Why is na2so4 not a molecular formula?
Because Na2SO4 is an ionic compound and so does not have actual molecules.
Results for precipitation of Ba(NO3) and Na2SO4?
Ba(NO3)2(aq) + Na2SO4(aq) ==> BaSO4(s) + 2NaNO3(aq).
How do you find the number of protons for formula Na2SO4?
2(11) + 16 + 4(8) = 70
What is the correct chemical formula for sodium sulfate?
Sulfate consists of 1 S, and 4 O and so has a charge of 2-. You can see this directly from the periodic table by checking what group these atoms are in. Sulfur and Oxygen are both in the 6th group, meaning they both have 6 valence electrons. So (6 electrons * 5 atoms) = 30 electrons. If we follow the octet rule (each atom must have 8 valence electrons for a full octet), then we need 2 more electrons. Sodium, Na, is in the 1st group on the periodic table, and therefore has 1 valence electron. So we need 2 sodium atoms, giving us the formula: Na2SO4 That is, 2 Na 1 S 4 O It's important to remember that when atoms 'share' their electrons by bonding, that BOTH atoms 'see' the electrons as theirs, meaning that, for example, although you may have 14 electrons between 2 atoms, as long as there is a single bond between the atoms they will both have full octets. For example: O2 :::O:O::: where : = pair of electrons.

What is the equation for dissociation of Na2SO4 when it dissolves in water?
Na2SO4(s) --> 2Na+(aq) + SO4-2(aq)
What is the total molar concentration of ions in a 0.350 M solution of the strong electrolyte Na2SO4 assuming complete dissociation?
1 mol Na2SO4 will dissociate to 2 mol Na+ and 1 mol SO42- Therefore 0.350 M Na2SO4 will dissociate to 0.350*2 = 0.700 mol Na+ and 0.350*1 = 0.350 mol SO42- Therefore the total concentration of ions is 0.700 mol + 0.350 mol = 1.050 mol.
What is the balanced chemical equation for the reaction between sulfuric acid and sodium hydrogen carbonate?
H2SO4 + 2NaOH ------------> Na2SO4 + 2H2O H2SO4 + 2NaOH ------------> Na2SO4 + 2H2O H2SO4 + 2NaOH ------------> Na2SO4 + 2H2O
Why is na2so4 not a molecular formula?
Because Na2SO4 is an ionic compound and so does not have actual molecules.
What substance does not evolve heat when dissolved in water Na2SO4 NaOH CaO NaCl?
Na2SO4 and NaCl
How many grams of sodium are there in 10.0 grams of sodium sulfate?
Na2SO4 10.0 grams Na2SO4 (1 mole Na2SO4/142.05 grams)(2 mole Na/1 mole Na2SO4)(22.99 grams/1 mole Na) = 3.24 grams of sodium -------------------------------
What kind of reaction is 2Na MgSO4?
Assuming you have a "+" sign in between the two reactants, this represents a single replacement reaction. They products will be Mg and Na2SO4.
