The product when an unsaturated hydrocarbon undergoes complete addition would be a saturated molecule. These saturated hydrocarbons becomes Alkanes where these molecules are only single-bonded in contrary to unsaturated hydrocarbons which have multiple bonds between atoms.
Answer:
2)HF bcz both fluorine and hydrogen are capable of forming only one covalent bond
Explanation:
flourine is short one electron to become stable while hydrogen has only one electron.Hydrogen cant give out its one electron fully thus it will share its one electron with flourine
Answer:
See explanation
Explanation:
From left to right, the oxides across period 3;
i) Period 3 oxides all appear white in colour. They are all crystalline solids and their melting points decrease from left to right.
ii) The volatility of period 3 oxides increases from left to right across the periodic table
iii) The metallic oxides on the right hand side adopt giant ionic structures. Silicon oxide which is in the middle of the period forms a giant covalent structure. Oxides of other elements towards the right hand side form molecular oxide structures.
iv) The acidity of oxides of period 3 increases from left to right. Metals on the left hand side form basic oxides while non-metals on the right hand side form acidic oxides. The oxide of aluminium in the middle is amphoteric.
v) The oxides of period 3 elements do not conduct electricity. However, the metallic oxides on the lefthand side conduct electricity in molten state. The non-metallic oxides on the right hand side are molecular hence they do not conduct electricity under any circumstance.
Answer:
The law of constant composition says that the composition of a homogeneous mixture is always the same
Explanation:
The law of constant composition that is also known as Proust's Law says that when two substances react with each other, to form a compound they will always do in a constant weight ratio, that is, the ratio of the masses between two substances that form a compound, must be proportional.
<span>This type of reaction is called a synthesis reaction. This type of reaction occurs when two or more components combine to form a single compound. During this formation, heat and energy is released, ergo it is an exothermic type of reaction.</span>
