What is the charge of the ion formed when nitrogen obeys the octet rule?
Answers
The octet rule is the understanding that most atoms seek to gain stability in their outer most energy level by filling the s and p orbitals of the highest energy level with eight electrons.
Nitrogen has an electron configuration of 1s²2s²2p³ this means that nitrogen has five valence electrons 2s²2p³ .
Nitrogen seeks out three additional electrons to fill the p orbital and gain the stability of a noble gas, 1s²2s²2p⁶ .
However, now nitrogen has 10 electrons and only 7 protons making it a -3 charge anion
N−³.

A fuel was burned for 5 min, increasing the temperature of 10.0 g of water with a density of 1.00 g/ml by 9.0 oC. The fuel released _____ ca
Answers
The fuel released 90 calories of heat.
Let suppose that water experiments an entirely sensible heating. Hence, the heat released by the fuel is equal to the heat absorbed by the water because of principle of energy conservation. The heat released by the fuel is expressed by the following formula:
[tex]Q = m\cdot c \cdot \Delta T[/tex] (1)
Where:
[tex]m[/tex] - Mass of the sample, in grams.[tex]c[/tex] - Specific heat of water, in calories per gram-degree Celsius.[tex]\Delta T[/tex] - Temperature change, in degrees Celsius.If we know that [tex]m = 10\,g[/tex], [tex]c = 1\,\frac{cal}{g\cdot ^{\circ}C}[/tex] and [tex]\Delta T = 9\,^{\circ}C[/tex], then the heat released by the fuel is:
[tex]Q = (10\,g)\cdot \left(1\,\frac{cal}{g\cdot ^{\circ}C} \right)\cdot (9\,^{\circ}C)[/tex]
The fuel released 90 calories of heat.

What is the volume percentage of 18 L of isopropanol in 45 L of water?
Answers
The volume percentage of 18 L of isopropanol in 45 L of water is 28.57%
Total solution = volume of water + volume of isopropanol
Total solution = 18L + 45L
Total solution = 63L
Volume of isopropanol = 18L
% volume of 18L isopropanol = 18/63 * 100
% volume of 18L isopropanol = 1800/63
% volume of 18L isopropanol = 28.57%
Hence the volume percentage of 18 L of isopropanol in 45 L of water is 28.57%

which turkey (15lb or 25lb) will thaw faster and why?
Answers
Answer:
15lb
Explanation:
A 15lb pound of turkey will thaw faster compared to 25lb because it's not only smaller but the weight of the turkey affects how temperature circulates throughout.
Hope this helps :)
The turkey weighing 15 lb will thaw faster as it has lesser mass, and required less time.
Thawing has been the process of warming up the substance for converting freezed to a soft liquid and solid. The time required for thawing has been proportional to the energy required to change the substance state.
The turkey has been given of weight 15 lb and 25 lb. The more the weight, there has been more energy has been required for thawing.
Thus, 15 lb turkey will thaw faster as compared to the 25 lb turkey.

To determine the melting point of ice, which procedure would best help measure the melting point temperature is to Mix ice with water until equilibrium is reached but some ice remains that is still melting.
Intermolecular forces are regarded as the forces of attraction or repulsion that exist or act between close particles of atoms, molecules, or ions.

Since the ozonolysis of the resulting alkene gave only one aldehyde, the starting material is but -2- yne.
Alkynes are a functional group characterized by the presence of the carbon - carbon triple bond. When an alkyne is reacted with sodium (Na) in liquid ammonia (NH3), the alkyne is converted to an alkene.

NEUTRALIZATION REACTION:
Neutralization reaction is a type of reaction between an acid and a base to form a salt and water. In a neutralization reaction, the hydrogen ion (H+) and hydroxyl ion (OH-) are released from the acid and base respectively and are combined to form water. An example is the reaction between hydrochloric acid (HCl) as an acid and sodium hydroxide (NaOH) as a base to form sodium chloride (NaCl) as salt and water (H2O).

compare how the water particles in the pot are behaving to how the water particles in the steam above the pot are behaving.
Answers
Answer: If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid. The most energetic particles at the surface escape from the surface of the liquid as a vapor as it gets warmer.
The water particles in a pot of boiling water are behaving very differently from the water particles in the steam above the pot.
The water particles in the pot are tightly packed together. They are constantly moving, but they are not free to move around as much as the water particles in the steam.
The water particles in the steam are much farther apart. They are also moving much faster than the water particles in the pot. This is because the steam has been heated to the boiling point, which means that the water molecules have enough energy to escape from the liquid state and become a gas.
