To determine the half-life of a substance from a graph, locate the point where the substance's concentration is half of its initial value. Then, find the time it took for the substance to reach that concentration. This time interval is the half-life of the substance.
To determine the initial value on a graph, look for the point where the graph intersects the y-axis. This point represents the initial value or starting point of the graph.
To determine the order of reaction from a graph, you can look at the slope of the graph. If the graph is linear and the slope is 1, the reaction is first order. If the slope is 2, the reaction is second order. If the slope is 0, the reaction is zero order.
To determine the mass of a substance, you can use a balance or scale to measure the amount of matter in the substance. The mass is typically measured in grams or kilograms.
To determine the heat of combustion for a substance, one can conduct a calorimetry experiment where the substance is burned in a controlled environment and the heat released is measured. This heat release is then used to calculate the heat of combustion for the substance.
To determine the rate-determining step from a graph, look for the slowest step where the rate of reaction is the lowest. This step will have the highest activation energy and will be the one that controls the overall rate of the reaction.
To determine the half-life of the substance, you can use the fact that after one half-life, the substance will be reduced to half of its original amount. In this case, after 40 days, the substance is reduced to one sixteenth of its original amount, which represents 4 half-lives (since 1/2^4 = 1/16). Thus, each half-life of this substance is 10 days.
To determine the wavelength from a graph, you can measure the distance between two consecutive peaks or troughs on the graph. This distance represents one full wavelength.
To determine the initial value on a graph, look for the point where the graph intersects the y-axis. This point represents the initial value or starting point of the graph.
To determine the phase constant from a graph, identify the horizontal shift of the graph compared to the original function. The phase constant is the amount the graph is shifted horizontally.
The answer depends on what the graph is of: the distribution function or the cumulative distribution function.
To determine velocity from an acceleration-time graph, you can find the area under the curve of the graph. This area represents the change in velocity over time. By calculating this area, you can determine the velocity at any given point on the graph.
To determine opportunity cost from a graph, you can look at the slope of the graph. The opportunity cost is represented by the ratio of the units of one good that must be given up to produce more units of another good. The steeper the slope of the graph, the higher the opportunity cost.
To determine the natural frequency from a graph, identify the peak point on the graph which represents the highest amplitude or resonance. The frequency corresponding to this peak point is the natural frequency of the system.
You would not use a graph to determine one person's height at a single point in time. You could use a line graph to track the height of a person over time. You could use a histogram to determine the heights of lots of people at one time.
If the graph is a function, no line perpendicular to the X-axis can intersect the graph at more than one point.
To determine the opportunity cost from a graph, you can look at the slope of the graph's line. The opportunity cost is represented by the ratio of the units of one good that must be given up to produce more units of another good. The steeper the slope of the graph, the higher the opportunity cost.
To determine the order of reaction from a graph, you can look at the slope of the graph. If the graph is linear and the slope is 1, the reaction is first order. If the slope is 2, the reaction is second order. If the slope is 0, the reaction is zero order.
