The number of moles of the gas in question. The ideal gas law states that
P x V = n x R x T
where, P is pressure, V is volume, n is number of moles of the gas, R is the ideal gas constant and T is temperature in Kelvin.
The combined gas law states that PV/T = k.
As you can see, the variable "n" is not in the combined gas law.
the dependent variable is the only thing that changes in an experiment
A controlled experiment is when a researcher manipulates and controls all variables except for the one being tested, known as the independent variable. This helps to isolate and determine the specific effects of the independent variable on the dependent variable.
Out of the non-metals you listed, nitrogen (N) is the only one that does not exhibit variable valency. Zinc (Zn), copper (Cu), and iron (Fe) can exhibit variable valency in certain compounds.
A control variable for making hot ice could be the amount of sodium acetate solution used, as keeping this constant will ensure that the only variable affecting the outcome is the temperature of the solution.
Ensuring that only one variable is changed or manipulated at a time, while keeping all other variables constant. This helps to isolate the effects of the independent variable on the dependent variable.
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.
No, you can only simplify an expression. To solve for a variable, it must be in an equation.
you can only solve for one in an equation so it can equal something
When an equation has a variable in it (only one), then there are only certainvalues the variable can have that will make the equation a true statement."Solving" the equation means finding those values for the variable.
You can have more than one variable, but it would take longer to solve.
To solve a system of equations by substitution, first solve one of the equations for one variable in terms of the other. Then, substitute this expression into the other equation. This will give you an equation with only one variable, which you can solve. Finally, substitute back to find the value of the other variable.
Use the definition of a function. If, for any value of one variable, there is only a single possible value of the second variable, then the second variable is a function of the first variable. The second variable is often called the "dependent variable". If you can solve an equation explicitly for the dependent variable, then it is a function. If you can NOT solve it for a variable, it may or may not be a function - it turns out that some equations are hard or impossible to solve explicitly for one of the variables.
It means that you manipulate the equation in such a way that the variable appears only on one side, by itself.
You solve the equation the same way as you would any other equation. Whether the variable is a fraction or otherwise will only become clear once you solve the equation. In other words, you don't initially KNOW whether the solution will be a fraction or not.
I have the feeling that you were looking to find a value for each variable in this equation. Unfortunately you can only solve for each variable in terms of the other variables in this equation.
In an ideal simple experiment, changing only one variable at a time ensures that any observed effects can be directly attributed to that specific variable. This isolation helps eliminate confounding factors, providing clearer insights into cause-and-effect relationships. By maintaining all other conditions constant, researchers can accurately assess the impact of the manipulated variable, leading to more reliable and valid conclusions.
I assume your trying to solve for the x variable? Use the quadratic formula (Google it) to find the roots to a second order equation (equation that contains a variable to power of 2). Using that equation, you get x values of 6 and -3. The only other way to solve it is with trial and error, which can be quite tedious.
