What is the independent variable in the magnesium oxide reaction?
The independent variable in the Magnesium Oxide Lab would be the Mass of the Magnesium Ribbon. This is because the mass of the product, i.e. Magnesium Oxide, depends on how much Magnesium is added.
What are the factors which affect rate of diffusion?
the factors which affect rate of diffusion is the factors that mixing one substance to another.
How do concentrations affect rate according to the rate law?
the rate increases as concentrations increase
How is the affect of concentration changes on the reaction rate seen in the rate law?
?
Why does temperature affect the rate of osmosis?
as the temperature increases, the rate of osmosis increases
Independent variable in measuring heart rate?
Time is the independent variable.
How does the concentration of glucose affect the rate of fermentation?
The higher concentartion of glucose means a slower rate of reaction for fermentation.
Dummy variable as an independent variable?
An independent variable is the variable you have control over, what you can choose and manipulate. It is usually what you think will affect the dependent variable. In some cases, you may not be able to manipulate the independent variable. It may be something that is already there and is fixed, something you would like to evaluate with respect to how it affects something else, the dependent variable like color, kind, time. Example: You are interested in how stress affects heart rate in humans. Your independent variable would be the stress and the dependent variable would be the heart rate. You can directly manipulate stress levels in your human subjects and measure how those stress levels change heart rate.
Identify the dependent and independent variable in this sentence Does the tempo of the music affect the human pulse rate?
dependent- human pulse rate independant- tempo of music
How would you write a dependent and independent variable for growth of crystals in a faster rate depending on temperature?
Dependent variable: growth of crystals Independent variable: temperature.
When measuring the breathing rate of fish over time the variable is independent or dependent?
independent
What is the difference between dependent asnd independent variables?
The independent variable is the one that the person doing the experiment changes themself. The dependant variable is the one that is recorded as results. For example, if investigating the effect of water on the rate of photosynthesis, you would change the amount of water and record how the rate of photosynthesis changes. Therefore, the amount of water is the independent variable and the rate of photosynthesis is the dependant variable.
What is the ratio that compares the amount of chage in a dependent variable to the amount of change in an independent variable?
Rate of Change
What is a ratio that compares the amount of change in the dependent variable to the amount of change in the independent variable?
rate of change. :)
What is a ratio that compares the amount of change in a dependent variable to the amount of change in an independent variable?
rate of change. :)
What is the physical significance of gradient define?
The gradient of a curve is the rate of change in the dependent variable relative to the independent variable.
How do you work out the rate of reaction when your independent variable is pH and your timing in seconds?
It is irrelevant what the independent variable is, whenever you work out rate of reaction you also divide 1 by the time in seconds. For example if it took 100 seconds your rate would be 0.01s-1.
