Which is an example of making a qualitative observation? measuring the speed of the chemical reaction describing how copper changes color in chlorine recording how long it takes to burn magnesium showing the results of an experiment with a graph

    qualitative observation talks about the quality. It can be either the colour, appearance etc. Measuring speed is something to do with numbers so that is quantitative, not qualitative. @nd one it talks about a colour change so that would be the answer.

    can you help with this one Which of these steps would most likely be part of a lab procedure? Write a hypothesis to answer a question. Write a title at the top of a completed lab report. Record the time to complete a chemical reaction. Create a question on the cause of a chemical reaction.

    In a lab we would record the time to find the rate of a chemical reaction. So I would go with the 3rd answer :)

    can you help me wish this on. Which statement best describes the variables in a controlled experiment? A.The independent variable is changed to see its effect on the dependent variable while all other conditions are unchanged. B.The dependent variable is changed to see its effect on the independent variable while all other conditions are unchanged. C.The independent variable is allowed to change, and the dependent variable is held constant to see what other conditions show a relationship. D.The dependent variable is allowed to change, and the independent variable is held constant to see what other conditions show a relationship.

    The dependent variable is what you are measuring for a change when you vary the independent's variable value.
