Answer:
<u>Calcium chloride does not have a covalent bond , it is an ionic bond (which means donation of electrons takes place )</u>. The charge of calcium ions is +2, while the charge of sodium ions is -1. The molecule of calcium chloride contains one calcium ion (+2) and two chloride ions (-1), resulting in an overall charge of 0, or neutral.
<u>IONIC BONDING IN CALCIUM CHLORIDE</u>
Electron sharing produces covalent compounds, while electron donation produces ionic compounds. is a salt with an ionic bond. This is because calcium takes up an electron to each of the chlorine atoms, resulting in ions for calcium and ions for chlorine. At room temperature, it behaves like a normal ionic halide and is solid. Calcium is a metal with a non-metal sulphate bond.
<u>Thus , Calcium chloride have ionic bonds present on them . No covalent bonds takes place in calcium chloride.</u>
The community with high blood varsity is represented with species richness
<h3>What is a community with high biodiversity?</h3>
A community with high biodiversity means that a region supports a wide variety of species, while low biodiversity implies that an area supports only a few. The reasons for variances in biodiversity are complex, but they include both natural and man-made causes.
The number of species per unit area is called Species Richness. If you have more number of species , more will be species richness hence stable will be the ecosystem. More species richness will contribute to increase in biodiversity also which is an important aspect biodiversity conservation.
