Acid Rain is formed when chemicals in the air get into rain and up the acidity levels!!!!!!
Hope this helps guys!
Answer:
yes acid rain
Explanation:
Water has a higher boiling point than expected because D. of the strong attraction between polar water molecules.
The higher boiling point of water is due to the strong attraction between polar water molecules. Water molecules are polar because of the unequal distribution of electron density between the oxygen and hydrogen atoms, resulting in a slightly positive charge on the hydrogen atoms and a slightly negative charge on the oxygen atom.
Thus, these partial charges create attractive forces called hydrogen bonds between neighboring water molecules, making it difficult to separate the molecules and requiring more heat energy to overcome these attractive forces and reach the boiling point.

(1) Energy is emitted.
(2) Energy is absorbed.
(3) The number of electrons decreases.
(4) The number of electrons increases.
Answer: The correct option is (1).
Explanation:
Whenever an atom in an excited state returns back to its ground state the energy is emitted out in the form of the radiation and the value of energy emitted can be determined by using the expression:
Where E = Energy of the radiation in joules
h = Planck's constant =
= Wavelength of the radiation in meters.

The alkali metal atom forms a +2 ion, while the alkaline earth metal atom forms a +1 ion.
The alkali metal atom has one less shell of electrons than the atom of the alkaline earth metal.
The alkali metal atom has one more shell of electrons than the atom of the alkaline earth metal.
Answer: The alkali metal atom forms a +1 ion, while the alkaline earth metal atom forms a +2 ion.
Explanation: Group 1 elements are called as alkali metals and group 2 elements are called as alkaline earth metals.
For example, Li is an alkali metal and Be is an alkaline earth metal.
Lithium(Li) has an atomic number of 3 and the electronic configuration is:
Li:
Thus lithium has to lose 1 electron and acquire 1+ charge to attain nearest noble gas configuration.
Berrylium(Be) has an atomic number of 4 and the electronic configuration is:
Be:
Thus berrylium has to lose 2 electrons and acquire 2+ charge to attain nearest noble gas configuration.
Answer:
a
Explanation:
The carbon atoms bind together to create the compound's framework. Therefore, the name of the hydrocarbon CH(CH)CH is n-octane.
Any member of a group of organic compounds comprised only of the atoms carbon (C) as well as hydrogen (H) (H). The carbon atoms bind together to create the compound's framework, as well as the hydrogen atoms connect to them in a variety of ways.
Petroleum as well as natural gas are mostly composed of hydrocarbons. They are used as fuels and lubricants, as well as raw materials to make polymers, fibers, rubbers, solvents, explosives, various industrial chemicals. The name of the hydrocarbon CH(CH)CH is n-octane.
Therefore, the name of the hydrocarbon CH(CH)CH is n-octane.

Answer is: n-octane.
Octane is the straight-chain alkane (an acyclic saturated hydrocarbon) with eight carbon atoms.
Carbons in octane have sp3 hybridization (carbon’s 2s and three 2p orbitals combine into four identical sp3 orbitals).
Orbitals in sp3 hybridization have a tetrahedral arrangement and form single (sigma) bonds.
Burning octane fuel is very fast chemical reaction, it happens in immediately.
Main products of the combustion of fossil fuels are carbon(IV) oxide and water.
Chemical reaction: C₈H₁₈ + 25/2O₂ → 8CO₂ + 9H₂O; ΔH = -5500 kJ/mol.
