If Jupiter’s gravity is 10 times stronger than the Earth’s, why aren’t you being pulled toward Jupiter?

Which action is the best example of a direct observation

luda_lava [24]

Since you didn't have any extra information about the question I'll be presenting an example from my own textbooks that I've used.

An example of a direct observation is listening to a cricket chirp at night, and counting the number of chirps per minute.

Direct Observation is where the evaulator watches the subject in their usual habitat without disrupting or altering it.

PLEASE HELP!!!! How many miles of F are there in 0.570 moles of C3H2F6 ?

kumpel [21]

There are 3.42 moles of F in 0.570 moles of C₃H₂F₆

<h3>Further explanation</h3>

Given

0.570 moles of C₃H₂F₆

Required

moles of F

Solution

The chemical formula of a compound shows the mole ratio of the constituent elements

In the compound C₃H₂F₆, the mole ratio of the elements is:

C: H: F = 3: 2: 6

So in 1 mol of C₃H₂F₆, there are 3 moles of C, 2 moles of H and 6 moles of F

And for 0.570 mol of C₃H₂F₆ :

$\tt moles~F=\dfrac{0.57}{1}\times 6=3.42$

1. What does an element’s position on the periodic table tell you about the element?

mr_godi [17]

The periodic table is a systematic arrangement of the elements. They are arranged according to their atomic number, the number of protons (which in the case of atoms is also the number of electrons) of each atom. Some of the properties of the elements can be predicted given their location in the periodic table.
