Which one of the following are quantitative? Choose 1 * 1. The liquid floats on water. 2. The metal is malleable. 3. The liquid has a temperature of 55.6 degrees C.

Hey there!

Quantitative measurements have data and statistics. For example, the liquid has a temperature of 55.6 degrees C is a quantitative measurement.

Let me know if this helps :)

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42

2.4

24

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
