Hydrogen combines with elements to give binary compounds known as hydrides.: Classify the given hydrides into different categories: `[NH_3, LiH, TiH, CH_4, NaH]`

Hydrogen combines with elements to give binary compounds known as hydrides.: Name the three categories of hydrides.

Classify the following hydrides into their different categories. NaH, NH_3 , CsH , KH, LaH_2 , SiH_4 , , LiH, NiH.

The combination of elements of form compounds is governed by the laws of chemical combination. Hydrogen combines with oxygen to form compounds, namely water and hydroge peroxide. 28 g of nitrogen is mixed with 12 g of hydrogen to form ammonia as per the reaction, N_2 + 3H_2 rarr 2NH_3 . Which is the 'limiting reagent' in this reaction? [Atomic masses: N = 14, H = 1]

Hydrides are binary compounds of hydrogen with other elements. Give one example each for elec tron deficient and electron rich hydride.

If an element is in its highest possibel oxidation state in a compound, it can act as an oxidising agent. If an element is in its lowest possible oxidation state in a compound, if can act as reducing agent. If an element is in the intermediate oxidation state in a compound, it can serve as both oxidising and reducing agent. Based on the above three guidelines, classify the following compounds into three categories and post them in the table given below. KMnO_4 , H_2O_2 , H_2C_2O_4 , FeSO_4 , HCIO_4 , SO_2 , Na_2S_2O_3 , K_2Cr_2O_7
