Compounds having covalent bonds are dinitrogen trioxide, carbon dioxide.
compounds having ionic bonds are calcium chloride, Magnesium nitride, sodium bromide, aluminum oxide.
Explanation:
When a positive charged cation gets bonded with negative charge anion by transferring its electrons the ionic bonds are formed. It is seen between metals and non-metals.
In covalent bonds the electrons are shared equally between two atoms. It is generally seen bonds between 2 non metals.
Dinitrogen trioxide : It is a covalent compound as bonding between two non metals is there ie nitrogen and oxygen.
In carbon dioxide carbon has four electrons in outermost shell which have strong attraction with nucleus cannot be lost neither it can accommodate 4 electrons to stabilize the valence shell. Thus sharing takes place and its covalent bonding.
In calcium chloride ionic bond is formed because calcium gives 2 electrons to each of the chloride atoms and thus gets 2+ charge on calcium. Sharing of electrons let the octet complete.
Magnesium nitride is formed when Mg loses 2 electrons to complete octet and nitride gains 3 electrons. The electrostatic attraction causes ionic bonding in it.
sodium bromide: Bromine is electronegative i.e electron donor and sodium is highly electrospositive hence sharing of electrons would cause electrostatic attraction between them.
aluminum oxide : The ideal situation of ionic bonds that is between metal and non-metals is present in aluminum oxide.
Answer is: the molecular formula is C₆H₁₀.
Chemical reaction: C₆Hₓ + yO₂ → 6CO₂ + x/2H₂O.
m(H₂O) = 0.9102; mass of the water.
n(H₂O) = m(H₂O) ÷ m(H₂O)
n(H₂O) = 0,9102 g ÷ 18 g/mol
n(H₂O) = 0,0505 mol.
From chemical reaction: n(H) = 2 · n(H₂O).
n(H) = 0.101 mol.
m(CO₂) = 2.668 g; mass of carbon dioxide.
n(CO₂) = 2.668 g ÷ 44 g/mol.
n(CO₂) = 0.0606 mol; amount of the substance.
n(CO₂) = n(C) = 0.0606 mol.
n(C) : n(H) = 0.606 mol : 0.101 mol.
n(C) : n(H) = 6 : 10; proportion of carbon and hydrogen atoms in cyclohexene.
Answer: The number of molecules of gas the flask contains is 
Explanation:
According to ideal gas equation:
P = pressure of gas = 1 atm (STP)
V = Volume of gas = 2.50 L
n = number of moles = ?
R = gas constant =
T =temperature = 273K (STP)
According to Avogadro's law:
1 mole of gas at STP contains =
molecules
Thus 0.112moles of gas at STP contains = 
molecules
The number of molecules of gas the flask contains is

Physical, Inorganic, Biochemistry, Analytical, and Organic
Physical chemistry deals with applying physics to the study of matter. It's also probably the most important branch. Inorganic chemistry deals with stuff that is chemically composed of elements other than carbon. The branch of Biochemistry concerns itself with living things. Analytical chemistry deals with analyzing and finding out what substances are present in a particular material and how much of each substance is present. Finally, organic chemistry deals with substances that are compounds of carbon.
