<h2>The required "options are (II), (III), and (IV)".</h2>
Explanation:
Postulates of Dalton's atomic theory which are scientifically accepted are:
- Atoms are indestructible.
- Compounds are combinations of different atoms.
- A chemical reaction changes the way atoms are grouped together.
Postulates of Dalton's atomic theory which are not accepted scientifically are:
- All atoms of the same elements are identical.
The theory states that the atoms of the same element are identical in every aspect but it is now scientifically proved that the same element should differ in their mass which is known as isotopes.
Answer:
It would produce ethane (CH₃CH₃)
Explanation:
Ethylmagnesium bromide (CH₃CH₂MgBr) is a Grignard's reagent.
It is a highly reactive substance, and as any alkylmagnesium bromide
(R-CH₂MgBr) it reacts with water to produce an alkane (R-CH₃). R stands for any carbon structure bonded to that functional group.
Answer:
What are the 12 major constellations?
What is the largest constellation?
Explanation:
Explanation:
To balance a chemical equation implies that we are conserving the number and mass of the reacting species.
Chemical equations must obey the law of conservation of mass "in a chemical reaction, matter is neither created nor destroyed".
This suggests that mass is conserved.
The number of atoms on the reactant side must be equal to that on the product end.
Before proceeding, check the species to see if they have equal number of atoms on both sides:
Fe + CuCI₂ → FeCI₂ + Cu
Elements reactants products
Fe 1 1
Cu 1 1
Cl 2 2
We can see that the equation is already balanced

Answer:
The three major types of bond are ionic, polar covalent, and covalent bonds. Ionic occurs majorly between metals and non-metals, which allows sharing of electrons to form an ionic compound. Whereas covalent bonding calls for complete transfer of electrons between atoms. Polar covalent bonds have unequaly shared electron-pair between two atoms.
Explanation:
a. Cu (Copper)-<em> ionic bonding
</em>
b. KCl (Potassium Chloride)
- <em>ionic bonding
</em>
c. Si (Silicon)
- <em>covalent bonding
</em>
d. CdTe (Cadmium Telluride)
- <em>polar covalent bonding
</em>
e. ZnTe (Zinc Telluride)- <em>polar covalent bonding
</em>
