2Na + 2H2O = 2NaOH + H2
Equations like this are always solved by simultaneous equations using 1Na +xH2O = aNaOH + bH2 which gives
1=a from Na
2x=a+2b from H
x=a from O
so x=1, b=0.5 then multiply the whole equation by 2 to get whole numbers without upsetting the balance.
To solve this stoichiometry problem, first calculate the number of moles of sodium hydroxide (NaOH) present in 200 grams. Then, using the balanced equation, determine the moles of sodium sulfate (Na2SO4) that will be formed. Finally, convert the moles of Na2SO4 to grams using the molar mass of sodium sulfate.
To find the volume, we need to use the ideal gas law equation: PV = nRT. First, convert 454 grams of hydrogen to moles by dividing by the molar mass of hydrogen (2.016 g/mol). Next, plug the values into the equation: (1.05 atm) * V = (moles) * (0.0821 L.atm/mol.K) * (298 K). Solve for V to find the volume in liters.
This is the balanced chemical equation for the Haber process, which produces ammonia. To solve, you can balance the equation by adjusting the coefficients in front of each compound to ensure that the number of each type of atom is the same on both sides of the equation. In this case, the balanced equation is N2 + 3H2 -> 2NH3.
In short just use algebra to get the equation below Start with [P + a*(n/V)^2] * (V - nb) = nRT which is the standard Van Der Waals equation and solve for n using algebra. which gives the 3rd order equation below. -(ab/V^2)*n^3 + (a/V)*n^2 - (bP+RT)*n + PV = 0 The simplest way to solve this equation is to enter it into Excel and graph it with multible values of n from 0 to whatever gets you to zero. The value that gives you zero is the answer. Be sure you use all the proper units for the other varables. Hope this helps.
The oxidation number of Phosphorus (P) in H3P2O7 is +5. This can be determined by assigning hydrogen an oxidation number of +1 and oxygen an oxidation number of -2, then setting up an equation to solve for the unknown oxidation number of Phosphorus.

Sure. You can always 'solve for' a variable, and if it happens to be the only variable in the equation, than that's how you solve the equation.
you don't answer an equation, you solve an equation
solve it
If you solve such an equation for "y", you get an equation in the slope-intercept form.
you can only solve for one in an equation so it can equal something
How do you use division to solve a multiplication equation?Answer this question…
It is not an equation if it does not have an equals sign. You could simplify it but not solve it.
There is no such thing as "solving integers". You can solve an equation, which means finding all the unknowns in that equation, but you can't solve an integer.
it is not an equation (there no equality in it!)
Please solve this equation.
Every equation has a solution.
