The oxidation number of an element is the charge the element would have if the compound that it is a part of consisted only of ions. When the oxidation number of an element increases, it is said to undergo oxidation. When the oxidation number decreases, t...
Discuss ionic and covalent bonding as well as the different physical and chemical properties of each. But let's step back and think about which electrons in each atom/element is actually participating in this bonding process. And how can one ...
已知F为抛物线y2＝4x的焦点，过点F且斜率为1的直线交抛物线于A，B两点，则||FA|﹣|FB||的值等于（ ）
Nitrogen is a critical element for plant growth and development. It makes up one-sixth of amino acids, the building blocks of proteins, and chlorophyll (the compound responsible for photosynthesis). Anhydrous ammonia is an effective source of nitrogen. It helps plants grow well and increases ...
The central atom in ammonia (NH3), which is nitrogen, is the one that undergoes hybridization to give sp3 hybridised molecules. We will figure out the entire process in the article.
A molecular formula describes which atoms are present in a molecule. The subscript number found after the elemental symbol indicates the number of atoms present for each element in the molecule.Answer and Explanation: The molecular formula of ammonium nitrate is NH4 NO3. The molecular formula ...
Besides hydrogen, what element wants 2 valence electrons in its outer shell? What are mineral acids and how do they differ from other acids? What is the pH of 0.255M CH3NH3I? Is this an acid or a base? Name five elements from the periodic table. ...
