The drawing of the Lewis dot structure for CH₃OCH₃ or acetone is drawn in the image attached below.

The Lewis dot structure for CH3COCH3 (acetone) is a way to represent the atoms and their bonding in the molecule using dots (electrons) around the symbol of the atom.

Each dot represents an electron. The Lewis dot structure shows that the 3 carbon atoms are double-bonded to one oxygen atom each and single-bonded to 3 hydrogen atoms each. Two oxygen atoms are each sharing two electrons with the carbon atoms. There are non-bonding electrons or lone pairs on the oxygen atoms. The Lewis dot structure gives a rough idea of the bonding in a molecule but it doesn't give information about the 3D geometry of the molecule.

Answer:

The statement that correctly compares the radii of Na and Na+ is as follows: Na has a larger radius than Na+ because Na+ has lost its outermost energy shell (option D).

The ionic radius is the distance from the nucleus to the outermost electrons in an ion while the atomic radius is the distance from the center of the nucleus to the outermost shell of an atom.

In a neutral atom, the atomic and ionic radius are the same, however, if the atom loses its outermost electron (positively charged or cation), the ionic radius is smaller than the atomic radius because the atom loses an electron energy shell.

Considering Na and Na+, it can be said that Na+ has lost its outermost energy shell because it is positively charged, hence, will possess a smaller radius than Na atom.

Emily believes Raphael's tomato sauce is overly garlicky, which may be determined by the unitary method's requirement for the number of garlic cloves.

If 500 mL of sauce contains 888 cloves, then 888 mL of sauce should contain 888 mL of cloves. According to this, there should be about 177.77 garlic cloves per 100 milliliters of tomato sauce. We must add nine more cloves to the 100mL requirement. This suggests that 177.77.9 garlic cloves must be added to 100.09 mL of sauce. But since Raphael used 121212 garlic cloves—more than 1600 cloves—in 900mL of sauce, we may say that option A is the real deal, which means Emily would find the sauce to be overly garlicky.

A Lewis structure, also known as a Lewis dot diagram, is a way to represent the bonding and non-bonding electrons in a molecule. It is named after Gilbert N. Lewis, who introduced it in 1916. A Lewis structure shows the chemical symbol of each atom in the molecule and the electrons that are involved in the chemical bonds. It is used to predict the molecular geometry, reactivity, and other chemical properties of a molecule.

The formal charge on the Nitrogen atom is 0 and each Oxygen atom has a formal charge of -1. A structure that minimizes the formal charge is one in which the formal charges on all the atoms are as close to zero as possible. This can be achieved by using the electrons from the central Nitrogen atom (N) to form single bonds with each Oxygen atom (O)

In mixture or solution, the ratio of an individual component to the total number of moles is called its mole fraction.

Let n1 be the number of moles of CaCl₂ and n2 be the number of moles of water.

molar mass of CaCl₂ = 111 g

weight = 25.5 g

number of moles = 25.5 /111 g = 0.22 moles.

Mole fraction of CaCl₂ = 0.105

then, n1/ (n1 + n2) = 0.105

0.22/ (0.22 + n2) = 0.105

0.22 = (n2 + 0.22) 0.105

0.105 n2 = 0.1969

n2 = 0.1969 /0.105 = 1.87.

The salt become less soluble in water when the temperature of the water decreases. Solubility increases with the increase in temperature.

The term solubility is the maximum quantity of solute that can dissolve in a certain quantity of solvent or quantity of solution at a specified temperature or pressure. An increase in temperature produces an increase in solubility. The effect of temperature on solubility can be explained on the basis of Le Chatelier's Principle. This principle is of value in predicting how much a system will respond to a change in external conditions. An increase in temperature puts a stress on the equilibrium condition and causes it to shift to the right. The stress is relieved because the dissolving process consumes some of the heat.

The floating or sinking of the object is explained by Archimedes' principle. When the weight force on an object is countered by the water's upward push, the thing floats. Water exerts an upward force proportional to the volume of the submerged object. Water depth or volume has no bearing on this upward force. The object will sink if the downward force of the weight is greater than the upward force of the water on it. The thing will rise if the contrary is true because rising is the opposite of sinking.
