What is the formula for diphosphorous trioxide?
P2O5 Reason: di means two. So, diphosphorus means there are two phosphorus atoms. Penta means five. So, pentoxide means there are five oxygen atoms. That's how you get P2O5.
What volume of dinitrogen pentoxide gas is produced when 500 ml of oxygen react completely in the following equation of STP 2N2 and 5O2 equals 2N2O5?
Using the stoichiometry of the balanced chemical equation, we find that 5 moles of oxygen gas will produce 2 moles of dinitrogen pentoxide gas. At STP (standard temperature and pressure, 0 degrees Celsius and 1 atm pressure), 1 mole of ideal gas occupies 22.4 L. So, first calculate the number of moles of oxygen gas from the given volume of 500 ml using the ideal gas law. Then, use the stoichiometry of the balanced chemical equation to determine the volume of dinitrogen pentoxide gas produced (in liters) at STP.
How do you balance P4O10 plus H2O equals H2PO4?
P4 3o2 ---> 2po5
What is the word equation for iron plus chlorine equals Iron chloride?
The word equation for iron plus chlorine yields iron chloride is: Iron + Chlorine → Iron chloride.
What is the ionic equation of cacl2 plus na2s equals cas plus nacl?
The balanced molecular equation is CaCl2 + Na2S -> CaS + 2NaCl. To write the ionic equation, we need to break down the reactants and products into their respective ions. This results in the ionic equation: Ca2+ + 2Cl- + 2Na+ + S2- -> CaS + 2Na+ + 2Cl-. Cross out spectator ions that appear on both sides of the equation to obtain the net ionic equation: Ca2+ + S2- -> CaS.
