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.
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.
P4 3o2 ---> 2po5
The word equation for iron plus chlorine yields iron chloride is: Iron + Chlorine → Iron chloride.
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.

It is an equation ... Anything with an equals is an equation 2+b=6 Anything without an equals is an expression 2+a
equation
Slope for the equation y equals 7 is zero.
If it doesn't have an "equals" sign, then it's not an equation. It's an "expression".
An expression does not have an equals sign, An equation has an equals sign,
I use "equals" or "is".
An example of a two step equation that equals 2 is 4 + 2x = 2. In this equation, x = -1.
An equation.
That word "equals" in there makes it an equation.
An equation. (Both "equals" and "equation" have the Latin root aequatio.)
