Is SO3 ionic or ionic using the stock system or molecular
vampirchik [111]

Answer:

Molecular

Explanation:

Using the rules for the nomenclature for naming binary covalent (molecular) compounds, the compound SO3 is named sulfur trioxide. The prefix tri- indicates that the oxygen has a subscript of 3 and that a molecule of sulfur trioxide has three oxygen atoms.

Choose the compound below that contains at least one polar covalent bond, but is nonpolar.
Ghella [55]

Answer:

  • The correct choice  is the letter <em>d. CF₄ is a compound that contains at least one polar covalent bond (four in fact), bust is nonpolar</em>.

Explanation:

For a compound to have <em>at least one polar covalent bond, but being a not polar compound</em>, the geometric configuration of the molecule must lead to a symmetrical distribution of the charges. This is because, in that way, the dipoles will cancel each other, producing a null net dipole, which makes a non-polar molecule.

Consider the four given molecules:

<u>a. SeBr₄</u>

Since, Se has six valence electrons, and it is bonded to four Br atoms, there will be one lone electron pair which will make that the charge is not symmetrically distributed, leading to a polar molecule. so this is not correct choice.

<u>b. HCN</u>

HCN's structure is linear: H-C≡N.

Nitrogen is more electronegative than carbon an so it is pulling the electrons on in the triple bond with carbon (C≡N) more than the hydrogen on the other side of carbon (H-C)

Therefore, there is a net a dipole moment towards N and the molecule is polar.

<u>c. ICl₃</u>

This is quite evident non-symmtrical and so you quickly can predict that is is polar.

<u>d. CF₄</u>

This molecule has four F atoms around a C atom.

Since, F is more electronegative than F, each C - F bond has a dipole moment (negative charge is closer to F atoms). Then, whe have four dipole moments (<em>covalent bonds</em>) on each CF₄ molecule.

Now, since the molecule is symmetric the four dipoles will cancel each other and the compund in nonpolar.

In conclusion, the correct choice  is the letter <em>d. CF₄ is a compound that contains at least one polar covalent bond (four in fact), bust is nonpolar.</em>

if slowing down is the response to seeing a blinking yellow light is it conditioned or unconditioned?
love history [14]

Answer:

Conditioned

Explanation:

Naturally, you do not slow down when you see a yellow light. That response is learned, therefore it is a conditioned response.

Wich statement describes how basic coffee cup calorimeter works
dybincka [34]

The correct answer is D) ) It uses the mass and specific heat of water along with a thermometer to measure the gain or loss of energy when a substance is added.

The statement that describes how a basic coffee cup calorimeter works is: "It uses the mass and specific heat of water along with a thermometer to measure the gain or loss of energy when a substance is added."

To measure the heat flow during a chemical reaction we use the device called Calorimeter. This device has a combustion chamber and above it, a metal container of water. With the use of a thermometer, we can measure the change in temperature. The combustion chamber releases the heat. This increases the temperature of the water.

The other options of the question were A) It measures the mass of a substance given the specific heat and temperature of water in a cup of known size. B) It measures the density of a substance given the mass, specific heat, and temperature of water in a cup of known size. C) It uses the mass and specific heat of water along with a pressure gauge to measure the gain or loss of energy when a substance is added.
