H2SO4 aq NaOH aq → Na2SO4 aq WebCount the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balanced. Since there is an equal number of each element in the reactants and products of BaBr2 + Na2SO4 = BaSO4 + 2NaBr, the equation is balanced. can ants harm laptops
If there are 65.2 grams of Na3PO4 , how many moles are there
Web10 apr. 2010 · 14. 2. Because the question asks how many ions are present, you need to multiply the moles of sodium sulfate by the number of ions it breaks down into in water. In this case, I believe the Na2 (SO)4 will dissociate to make two Na+ ions and one (SO)4 ion (total of 3 ions). May 12, 2008. WebIf the ions are in the same medium, then the value of ε is the same. Thus, the ratio of the force of attraction of the two sets of ions is F F' = q 1q 2 q 1 'q 2 ' = (+2)(-2) (+3)(-1) = −4 −3 = 1.3 The force of attraction between a calcium ion and a sulfate ion is 1.3 times greater than the force of attraction between an aluminum ion and a ... WebAnswer (1 of 2): The sulphate ion has a charge of -2. The sodium has a charge of +1. Therefore there are 2 sodium ions in a molecule of sodium sulphate. A mole is 6.022 * 10^23 Number of ions equals 2 * 3.7 * 6.022 * 10^23 = 4.5*10^24 I calculated to 2 s.f. so that you can do the calculation ... can ants go into your ears
