Fish will reproduce both ways
Answer: Because acetic acid in solution exists as a mixture of acetic acid & dissociated acetic acid (acetate)
Hope this helps!
Answer:
- The third choice: <u><em>Only temperature (degrees C) is the independent variable.</em></u>
Explanation:
The <em>independent variable</em> is generally represented on the horizontal axis.
In the graph the horizontal axis is labeled Temperature (°C), so this is the independent variable.
The <em>dependent variable</em><em> </em>is represented in the vertical axis. In the shown graph it is Flow time (s).
The independent variable is the input of the function or relation and it determines or explains the dependent variable.
So, on the given graph you can you can tell that the flow time (measured in seconds) depends on, or is determined by, the temperature (measured in °C).
The<em> slope</em> of the trend line is the measure of how much the dependent variable changes, on average, when the independent variable changes one unit. For the shown graph, the slope is change in flow time divided by the change in temperature.
The answer is b. the water molecules are more closely packed together in ice than in water <span />
Answer:
A) Separating funnel method
B) Simple Distillation
C) Evaporation
D) Sublimation
E) It is based on the principle of separation whereby even though two substances are dissolved in the same solvent, their respective solubilities could be different. Thus, the component that has more solubility will rise fastest and will therefore get separated from the mixture.
Explanation:
A)
B) Kerosene and petrol are both miscible liquids and the difference in their boiling point temperature is not more than 25°C. Thus, we make use of Simple distillation.
C) Can be separated by evaporation where the water is boiled and it evaporates and leaves the salt behind
D) To separate camphor from salt, we use sublimation so the camphor can change directly from solid to the gas state without passing through the liquid state.
E) Chromatography is used to separate components of a mixture.
It is based on the principle of separation whereby even though two substances are dissolved in the same solvent, their respective solubilities could be different. Thus, the component that has more solubility will rise fastest and will therefore get separated from the mixture.
