Answer:
In writing the electron configuration for nitrogen the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for N goes in the 2s orbital. The remaining three electrons will go in the 2p orbital. Therefore the N electron configuration will be 1s22s22p3.
Explanation:
hope you get it right:)
Answer:
the electron configuration for N will be 1s^2 2s^2 2p^3

aluminum can be used to make soft drink cans because of which property?
A. It can be hammered into a thin sheet (malleability)
B.it can reflect light (shininess)
C.It can be drawn into long wires(ductility)
Answer:
A
Explanation:
Malleability describes the property of a metal's ability to be distorted below compression. It is a physical property of metals by which they can be hammered, shaped and rolled into a very thin sheet without rupturing. A soda can's walls are very thin, and therefore express the malleability of aluminum.

what is the purpose of an auxiliary complexing agent?
Answer:
prevent hydroxide formation
Explanation:
negative ions form when atoms _______ valence electrons.
Answer:
Negatively charged ions are called anions, and an anion is formed when an atom gains an electron. Thus, the atom has an extra charge of electrons,
Explanation:
so it becomes negatively charged.
Negative ions (or anions) are atoms that have gained electrons.
Electrons have a negative charge so if an atom is getting more of them, it's becoming more negative.
what additional reaction product would result if naoh was used as a base in this reaction instead of k2co3?
Answer:
What reaction product would result if NaOH was used as a base in this reaction instead of K2CO3? If sodium hydroxide was used as the base of the reaction, then the reaction product formed would be an ethyl alcohol because it would undergo a hydrolysis reaction with addition of iodoethane
The entire carbonation reaction demonstrates how potassium carbonate (K2CO3) combines with water and carbon dioxide to create potassium bicarbonate (KHCO3) when exposed to combustion flue gases at low temperatures (40 to 80 °C) (Reaction 1)
What takes place when K2CO3 and water interact?In an extremely violent and exothermic reaction, potassium carbonate splits into potassium and carbonate ions when it interacts with water. When the ions interact, potassium oxide and carbonic acid are created.
K2CO3 come from : Potassium carbonate is a common ingredient in the manufacture of soap and glass. Additionally, it serves as a light drying agent. This substance is used as a buffering agent in numerous wine making procedures. Another usage for potassium carbonate is as a fire extinguisher.
K2CO3 created : Commercially, potassium carbonate is made by reacting potassium hydroxide with carbon dioxide:
2 KOH + CO2 = K2CO3 + H2.
K2CO332H2O sesquihydrate crystallizes from the solution ("potash hydrate").
The anhydrous salt is produced by heating this solid at 200 °C (392 °F).
It disintegrates into K2O+CO2 around 1200 C. (allreaction)
By converting carbonate into carbon dioxide and water, potassium carbonate can act as a base by forming potassium hydroxide.

Im doing a science project and need examples and non-examples of an Atom. some examples of an atom is neon, hydrogen, argon, etc so I got that part. But what are some non-examples of an atom and why?
Answer:
Anything not on the periodic table is an element non example! ... So, for a substance to be an element, all of its atoms must have the same number of protons. Examples of elements include hydrogen, lithium, nickel, and radium.
Explanation:
Non-examples of an atom refer to entities that are not considered atoms.
Molecules consist of two or more atoms chemically bonded together. They are not considered individual atoms because they contain multiple atoms connected by chemical bonds.
Ions are electrically charged particles formed when atoms gain or lose electrons. They can be positively charged (cations) or negatively charged (anions).
Subatomic particles are the constituents of atoms. They include protons, neutrons, and electrons.
Compounds are substances composed of two or more different elements chemically combined.

A student wants to calculate the heat gained of 100 grams of water in order to
calculate the specific heat of a metal in the following problem. The water is
heated from 25C to 50C when the metal is added. The specific heat of water is
4.18 J/gºC. Use Q=m xCxT*
The quantity of heat gained to raise the temperature from 25.0°C to 50.0°C is 10,450 Joules.
Given the following data:
Mass of water = 100 gramsInitial temperature = 25.0°CFinal temperature of water = 50.0°CSpecific heat capacity of water = 4.18 J/g°CTo find the quantity of heat gained:
Mathematically, heat capacity or quantity of heat is given by the formula;
[tex]Q = mc\theta[/tex]
Where:
Q represents the heat capacity or quantity of heat.m represents the mass of an object.c represents the specific heat capacity.∅ represents the change in temperature.Substituting the values into the formula, we have:
[tex]Q = 100(4.18)(50 - 25)\\\\Q = 418(25)[/tex]
Quantity of heat = 10,450 Joules.

How many significant digits are found?
Answer:
4
Explanation:
There are 4 significant figures because when there is not a decimal, then only numerical values over 0 are counted. So the numbers counted in sig figs are 2049, and none of the other 0s.
So if it was 204,900,000,000.0, then it would have 12 significant figures.
