A student compared some chemical and physical properties of three pure substances. Her data are recorded in the chart above. What is a logical conclusion the student can draw about pure substances? A student compared some chemical and physical properties of three pure substances. Her data are recorded in the chart above. What is a logical conclusion the student can draw about pure substances? 1.Pure substances have the same chemical and physical properties.
2. Pure substances have the same chemical properties, but different physical properties.
3. Pure substances have the different chemical properties, but the same physical properties.
or 4. Pure substances have different chemical and physical properties.
i have the same question. i took the test and got an 80%. the answer for this question is 3, or C
Thank you zayn
Thank you very much ☺
thanks @zaynmalik1D
thx!!
It's B not C
B: " B. Pure substances have the same chemical properties, but different physical properties."
C: " C. Pure substances have the different chemical properties, but the same physical properties."
To draw a logical conclusion about pure substances based on the data recorded in the chart, we should analyze the information provided. However, since the chart is not provided in the question, we are unable to directly examine the data.
In general, pure substances refer to materials that consist of only one type of molecule or atom. They have consistent and definite chemical and physical properties.
Based on the answer choices given, let's consider each option and determine the logical conclusion:
1. Pure substances have the same chemical and physical properties: This conclusion is unlikely since different pure substances typically have different chemical properties.
2. Pure substances have the same chemical properties but different physical properties: This conclusion seems plausible, as pure substances can have distinct physical properties while sharing similar chemical properties.
3. Pure substances have different chemical properties but the same physical properties: This conclusion is unlikely since pure substances tend to have consistent physical properties, but distinct chemical properties.
4. Pure substances have different chemical and physical properties: This conclusion is also possible, as different pure substances frequently exhibit both varying chemical and physical properties.
Without access to the chart, we cannot determine the correct answer definitively. However, option 2, "Pure substances have the same chemical properties, but different physical properties," appears to be the most logical conclusion based on general knowledge about pure substances.
