The molecular geometry is square planar.

According to the Valence Shell Electron Pair Repulsion theory (VSEPR), the shape of a molecule is determined by the number of valence electrons surrounding the outermost shell of the central atom in the molecule.

In this case, the expected geometry based on VSEPR theory is octahedral. However, the lone pairs on opposite sides of the four single bonds leads to a square planar molecular geometry.

For each situation below, state whether water will move into the cell, move out of the cell, or stay the same.
Firdavs [7]
Water moves from an area of higher water potential (aka. "more water" in simple language) to an area of lower water potential (aka. "less water" in simple language).

For A, cells in carrots have water stored in their cytoplasm, where many soluble substances may be found (e.g. sodium ions). On the other hand, pure water has no other soluble substances other than the water molecules (I.e. H2O). Pure water will thus have a higher water potential as compared to the water in carrot cells, and so, water will move from pure water into the carrot cells via osmosis down a concentration gradient.

B. Corn syrup is water that has high concentrations of sugars, thus it is very likely to have a lower water potential than the cells of carrots. Water will move from within the cells of carrots and out to the corn syrup, down a concentration gradient.

C. The water in carrot cells will stay the same, since carrot cells have the same water potential as the surrounding solution which has the same water potential as cytoplasm.

Hope this helps! :)

Fluorine + sodium chloride → sodium fluoride + __________. What is the missing chemical name?
Deffense [45]

Answer:

Chlorine (Cl)

Explanation:

The equation would be:

F+NaCl  → NaF + Cl

This is because no atom is lost in a reaction. Chlorine would be the missing chemical as it is on the other side of the equation and needs to be accounted for on the products side.

 Describe and name the parts of the atom.
Setler79 [48]

Answer:

The parts of an atom are<em><u> protons, electrons, and neutrons.</u></em>

A proton is positively charged and is located in the center or nucleus of the atom.

Electrons are negatively charged and are located in rings or orbits spinning around the nucleus.

The number of protons and electrons is always equal.
