trains students in the state symbols for reactants and products in a chemical equation.
Elements in their elemental form and compounds are divided into covalent and ionic compounds for classification and easier identification of relevant state symbols.

must the number of people at a party who do not know an odd number of other people be even?
Solution
In a graph theory, know that “the number of vertices of odd degree is even”.
By applying the above principle to the graph with each person as a vertex and an edge between
two people who do not know each other. Then yes. it must the number of people at a party who
do not know an odd number of other people be even.
hi guys,i have been getting useful materials for my students teaching, the least i can do for thanking all of you is by uploading this file on acids,bases and salts
thanks
Acids are substances that form hydrogen ions, H+(.pdfaquapariwar
Acids are substances that form hydrogen ions, H+(aq), when dissolved in water In
acid solutions there are more H+ ions than OH- ions. Bases which are soluble in water are called
alkalis e.g. NaOH sodium hydroxide, KOH potassium hydroxide or Ca(OH)2 calcium hydroxide.
Bases which are water insoluble include CuO copper(II) oxide, MgO magnesium oxide. After a
neutralisation, the salt solutions consist of a mixture of positive and negative ions (and their
names are in the salt name!) e.g. sodium chloride (NaCl) is a mixture of Na+ and Cl- ions,
calcium chloride (CaCl2) is a mix of Ca2+ and Cl- ions; magnesium nitrate (Mg(NO3)2) is a
mix of Mg2+ and NO3- ions, aluminium sulphate (Al2(SO4)3) consists of Al3+ and SO42- ions
etc. You can test for chloride ions by adding a few drops of dilute nitric acid followed by a few
drops of silver nitrate solution. If chloride ions are present you will see a white precipitate of
silver chloride. However, chlorine water itself will contain chloride ions as chlorine in aqueous
solution disproportionates to form chloride and chlorate(I) ions. Cl2 + H2O --> Cl- + ClO- +
2H+ Testing for the presence of nitrate via wet chemistry is generally difficult compared with
testing for other anions, as almost all nitrates are soluble in water. In contrast, many common
ions give insoluble salts, e.g. halides precipitate with silver, and sulfates precipitate with barium.
The nitrate anion is an oxidizer, and many tests for the nitrate anion are based on this property.
Unfortunately, other oxidants present in the analyte may interfere and give erroneous results.

Unveiling the Secrets How Does Generative AI Work.pdfSam H
At its core, generative artificial intelligence relies on the concept of generative models, which serve as engines that churn out entirely new data resembling their training data. It is like a sculptor who has studied so many forms found in nature and then uses this knowledge to create sculptures from his imagination that have never been seen before anywhere else. If taken to cyberspace, gans work almost the same way.

Memorandum Of Association Constitution of Company.pptseri bangash
www.seribangash.com
A Memorandum of Association (MOA) is a legal document that outlines the fundamental principles and objectives upon which a company operates. It serves as the company's charter or constitution and defines the scope of its activities. Here's a detailed note on the MOA:
Contents of Memorandum of Association:
Name Clause: This clause states the name of the company, which should end with words like "Limited" or "Ltd." for a public limited company and "Private Limited" or "Pvt. Ltd." for a private limited company.
https://seribangash.com/article-of-association-is-legal-doc-of-company/
Registered Office Clause: It specifies the location where the company's registered office is situated. This office is where all official communications and notices are sent.
Objective Clause: This clause delineates the main objectives for which the company is formed. It's important to define these objectives clearly, as the company cannot undertake activities beyond those mentioned in this clause.
www.seribangash.com
Liability Clause: It outlines the extent of liability of the company's members. In the case of companies limited by shares, the liability of members is limited to the amount unpaid on their shares. For companies limited by guarantee, members' liability is limited to the amount they undertake to contribute if the company is wound up.
https://seribangash.com/promotors-is-person-conceived-formation-company/
Capital Clause: This clause specifies the authorized capital of the company, i.e., the maximum amount of share capital the company is authorized to issue. It also mentions the division of this capital into shares and their respective nominal value.
Association Clause: It simply states that the subscribers wish to form a company and agree to become members of it, in accordance with the terms of the MOA.
Importance of Memorandum of Association:
Legal Requirement: The MOA is a legal requirement for the formation of a company. It must be filed with the Registrar of Companies during the incorporation process.
Constitutional Document: It serves as the company's constitutional document, defining its scope, powers, and limitations.
Protection of Members: It protects the interests of the company's members by clearly defining the objectives and limiting their liability.
External Communication: It provides clarity to external parties, such as investors, creditors, and regulatory authorities, regarding the company's objectives and powers.
https://seribangash.com/difference-public-and-private-company-law/
Binding Authority: The company and its members are bound by the provisions of the MOA. Any action taken beyond its scope may be considered ultra vires (beyond the powers) of the company and therefore void.
Amendment of MOA:
While the MOA lays down the company's fundamental principles, it is not entirely immutable. It can be amended, but only under specific circumstances and in compliance with legal procedures. Amendments typically require shareholder

Chemical equations
1. CHEMICAL EQUATIONS
Practice your covalent bonding to find how the non-metal atoms such as the group 7 ones
form molecules using covalent bonding to get octet configuration
O2 and Cl2
State symbol of atoms in their elemental forms
What are the state symbols of metals from group I, II, III?
Solid
Group IV What are the state symbols of carbon?
carbon is usually in the form of graphite which is a solid, the state symbol is C(s).
Group V nitrogen atoms form N2 molecule which isin gaseous state at room temperature
Phosphorus is a solid at room temperature. the state symbol is P(s).
Group VI oxygenatoms form O2 molecule which is in gaseous state at room temperature
Sulphur is a solid at room temperature. Its state symbol is S(s).
Group VII flourineatoms form F2 molecule which is in gaseous state
Bromine atoms form Br2 molecule which is in liquid state. Its state symbol is Br2(l).
Iodine atoms form I2 molecule which is in solid state. Its state symbol is I2(s).
2. Group VIII the noble gases are monoatomic, which means they exist as single atoms in
the gaseous state.
Next you need to know the state symbol of the commonly seen compounds.
Compounds are grouped into two types – ionic and covalent
As you know, ionic compounds are made up of oppositely charged ions and you must be able
to recognise from their formula that they are ionic compounds.
On the other hand, covalent compounds are made up of all non-metals atoms.
Insoluble ionic compounds are solids are room temperature because they have very high
melting points. But soluble ionic compounds may be in aqueous state, which means that they
are dissolved in water.
Most covalent compounds are either in liquid or gaseous states, except a few exceptions like
sand (SiO2). But acids (the big 3, hydrochloric acid, nitric acid and sulphuric acid) are usually
in aqueous state.
Sort the following compounds into covalent and ionic compounds and their state symbols at
room temperature.
H2O HCl
CO2 CH4
CaCO3 H2SO4
CaO NaOH
Al2(SO4)3 HNO3
Ca(OH)2 CCl4
Use the solubility table below to help you!
reagents soluble insoluble
Carbonates sodium, potassium & ammonium the rest
Calcium, sodium, potassium &
Bases
hydroxides ammonium the rest
Metal Oxides Group I metals’ oxides only Other metals
Non-metal Oxides Most CO, NO, SiO2
chlorides the rest lead, sliver
salts Nitrates ALL soluble -
sulphates the rest barium, lead
3. Try to balance the following equations, the key is to balance those atoms that appear only
once first, and then balance hydrogen and oxygen atoms last.
H2+ O2H2O
CaO + HClCaCl2 + H2O
CH4 + O2 CO2 + H2O
N2 + O2NO2
H2SO4 + NaNa2SO4 + H2O
CH4 + Cl2CCl4 + HCl
Na2O + H2O NaOH
Na + H2O NaOH + H2
Write out the following chemical equations
Calcium oxide + nitric acid calcium nitrate + water
