The variable to measure when removing oil from sand is the oil concentration remaining in the sand after the removal process. This can be quantified by analyzing the oil content in the sand before and after the removal process to assess the efficiency of the oil-removal method.

What is back formation?
A back-formation is a process by which a new word is formed by removing a morpheme of an older word, such as the word "burgle" deriving from the word "burglar", or a word created in such a manner.
What role of potassium hydroxide in a volumeter in respiration experiment?
Potassium hydroxide in a volumeter is used to absorb carbon dioxide produced during respiration. This helps to ensure that the volume of gas being measured is only the oxygen consumed and not affected by the carbon dioxide produced. Potassium hydroxide reacts with carbon dioxide to form potassium carbonate and water, effectively removing carbon dioxide from the system.
Can elements with variable valency can be stored in water?
Yes, elements with variable valency can be stored in water. However, the reactivity of the element will determine how stable it is in water. Some elements may react with water to form oxides or hydroxides, while others may remain stable. It is important to consider the specific properties of the element in question when storing it in water.
How do people change the state of matter?
If the matter is in a liquid state, add heat to turn liquid to vapor. Remove heat to form a solid. If it is in the form of a vapor, remove heat to form a liquid, and remove more heat to form a solid. If it is in the form of a solid, add heat to turn it into a liquid. Add more heat to turn into a vapor.
Transition metals most often form ions with what charge?
most transition metals form ions with a 2+ charge.
What is a measured variable?
A measured variable is a quantity or attribute that can be quantitatively assessed or determined using a measuring instrument. It provides numerical information about a specific characteristic or property of a system, process, or entity. Examples include temperature, weight, time, and distance.
What in general is the value measured by the horizontal axis called?
The variable plotted along the horizontal (x) axis is termed the independent variable. The variable plotted along the vertical (y) axis is termed the dependent variable. Usually equations of curves are given in the form y = f(x) meaning that the y value is dependent on the x value.
What is The thing you change in an experiment?
The chemical composition and physical state of substances can change during an experiment.For example two reactants in solid or liquid form can react in an experiment to give a product in a gaseous form.
What is verb form for the word variABLE?
Vary. We can vary the speed of the engine.
What serves as a standard of comparisons to evaluate the effect of the independent variable on the dependent variable variable?
There cannot be one since the answer depends on the form in which the effect is measured: whether the effect is qualitative or quantitative. There are various non-parametric measures of correlation or concordance. For data that are more quantitative there are more powerful tests such as the F-test for independent Normal distributions.
What is slack variable?
Slack variable is a variable that is added to a constraint to switch form an inequality to equatlity equation.
What is x when in an expression it is the form of x?
'x' is a fixed but unknown amount. It is not a VARIABLE!!!!
Is newton a dependent variable?
Any form of numerical measurement can be a dependent variable (or an independent one).
Is the appropriate unit for measuring an oil tanker tons cubic inches ounces or feet?
It should be measured by feet if it is in cubic form.
What serves as a comparison to evaluate the effect of the the independent variable on the dependent variable?
