Answer:

Make a PBJ

Explanation:

First you remove the bread from the fridge, cabinet, ect.

Then you remove 2 slices from the packaging and place them on a clean spot on the counter, a paper towel, or a plate. (You can put them in the toaster if you prefer toasted bread)

Retreive the peanut butter and jelly from their respective places, and bring them to the area with your bread. If you are toasting the bread, wait til the toaster is done, then place your slices back on your surface.

Now, take a butter knife and spread peanut butter on one side of a peice of bread. Make sure the edges are covered for the best result.

Do the same with the Jelly.

Now put both peices of bread together, the Peanut butter and jelly facing each other. Finally enjoy your sandwich!

The bond between carbon and hydrogen is one of the most important types of bonds in chemistry. The length of an H—C bond is appr

nata0808 [166]

Answer:

The dipole moment of H-C bond will be smaller than that of an H-I bond.

Explanation:

The electronegativity of iodine is greater than that of hydrogen.As a result the iodine atom tends to attract the bond electron pair of H-I bond towards itself creating a bond dipole which does not occur in case of H-C bond as the electronegativity of carbon and hydrogen are almost same.

That"s why dipole moment of H-C bond is smaller than that of H-I bond.

Rank the compounds in each set in order of increasing acid strength.

Viktor [21]

Answer:

See explanation

Explanation:

For this question, we have to remember the effect of an atom with high electronegativity as "Br". If the "Br" atom is closer to the carboxylic acid group (COOH) we will have an inductive effect. Due to the electronegativity of Br, the electrons of the C-H bond would be to the Br, then this bond would be weaker and the compound will be more acid (because is easier to produce the hydronium ion $H^+$ ).

With this in mind, for A in the last compound, we have 2 Br atoms near to the acid carboxylic group, so, we will have a high inductive effect, then the C-H would be weaker and we will have more acidity. Then we will have the compound with only 1 Br atom and finally, the last compound would be the one without Br atoms.

In B, the difference between the molecules is the position of the "Br" atom in the molecule. If the Br atom is closer to the acid group we will have a higher inductive effect and more acidity.

See figure 1

Describe the process of convection and how it contributes to seafloor spreading

kobusy [5.1K]

Answer:

Seafloor spreading and other tectonic activity processes are the result of mantle convection. ... Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense.
