Because their elemental compositions can vary continuously, rather than being fixed at particular values.
Metals such as iron, nickel, platinum, and palladium can form bonds with hydrogen to create metal hydrides. These metal hydrides are often used in various industrial processes, including hydrogen storage and purification.
Heating a chemical compound can cause it to undergo decomposition, leading to the release of elements present in the compound. This process is known as thermal decomposition and is often used to extract elements from compounds in laboratory and industrial settings.
True. Chemical properties are characteristics that can only be observed when a substance undergoes a chemical change, such as reactivity with other substances or the ability to undergo a chemical reaction.
Aluminum compounds can act as acids because they can donate protons (H+) in solution. This is due to the ability of aluminum to form Al3+ ions, which can undergo hydrolysis to release H+ ions. As a result, aluminum compounds can exhibit acidic properties in various chemical reactions.
Yes, all ionic compounds consist of ions formed from at least two different elements - one positively charged cation and one negatively charged anion. This is what allows them to have an overall neutral charge and form ionic bonding.
Ionic hydrides are called true hydrides because they are formed by the direct combination of hydrogen with an electropositive metal, resulting in a compound with characteristics typical of hydrides. These hydrides exhibit ionic bonding between the metal cation and the hydrogen anion, hence the name "ionic hydrides".
because aklai are soluble in water with compltely and alkai earth metal are partially dissolve in water thats they are called true hydrides
True
true
By convention chemical compounds containing carbon are considered organic chemicals; but this definition is not entirely true.
Yes, in a chemical reaction, atoms are rearranged to form new molecules and compounds. Chemical bonds between atoms are broken and new bonds are formed, resulting in the creation of different substances.
They can be reversed by physical changes...
This is simply because they contain the H- anion and are like the the halides of metals which are generally ionic. For me a covalent hydride is just as true as an ionic one some folk get very hung up on names and categorising.
A binary compound is formed from two different chemical elements.
They are both "Chemically joined" so True :3
Yes, after the Law of definite proportions; but now it is clear that this law is not applicable to all known chemical compounds.
Yes, during a chemical reaction, existing chemical bonds are broken and new bonds are formed, resulting in the creation of new molecules and compounds. This process involves the rearrangement of atoms to form different substances with unique chemical properties.
