Hydrides are compounds that consist of hydrogen and one or more other elements. In other words, hydrides are chemical compounds that contain a hydrogen ion (H-) or a hydrogen atom (H) bonded to one or more other atoms. The properties of hydrides can vary widely depending on the other elements involved in the compound. NH3 (ammonia) and HF (hydrogen fluoride) are both examples of hydrides. Although they don't contain the traditional H- ion, they still contain hydrogen atoms bonded to other elements. In the case of NH3, there are three hydrogen atoms bonded to one nitrogen atom. In the case of HF, there is one hydrogen atom bonded to one fluorine atom. The reason NH3 and HF are considered hydrides is because they exhibit similar chemical properties to other hydrides. For example, NH3 can act as a weak base and can donate a hydrogen ion (H+) in certain chemical reactions. HF is a strong acid and can donate a hydrogen ion in solution. Additionally, both NH3 and HF are polar molecules, which means they have a partial positive charge on the hydrogen atom and a partial negative charge on the other atom(s), giving them unique chemical properties. In summary, hydrides are compounds that contain hydrogen atoms or ions bonded to other elements. NH3 and HF are considered hydrides because they contain hydrogen atoms bonded to other elements and exhibit similar chemical properties to other hydrides.
It can't cover all reactions as there are loads of examples an examiner could throw at you. Best strategy to adopt is to learn the method and apply to a few examples. 👍
SORRY BUT I JUS WANTED TO ASK U CAN I GET AN A* IN A LVL CAIE CHEM BUT JUS UR CONTENT REVISISNG ECTB N DOING PAST PAPERS ALOTT WILL IT GGET ME A GOOD GRADE COZ IVE SEEN MANY YT VIDS BUT THEY AINT LIKE URS N U COVER EVEYTHING I JUS GO 1 QUESTION CAN U PLEASE ANSWER🤔
Anything is possible. They key things are understanding the content through watching my videos and linking this with your textbook. You need to run through past paper questions and learn from the mark scheme. I see it like learning to drive. We can all read about the rules of the road in a book, but that doesn't mean we can hop in the car and drive it. So we shouldn't be doing the same for A Level Chemistry, too. 🙂
@@AlleryChemistry THNAK YOU SO MUCH IT MEANS ALOT UR LITERALLY HELPING A MISERABLE SOUL I APPRECIATE DAT THANK UUUU MAY GOD BLESS U SUCH AN AMAZING TEACHER FR
