Answer:
atom &bond
Explanation:
atom is strong due to the bond
Answer: Ionic bonds form only between metals and nonmetals. That's because metals “want” to give up electrons, and nonmetals “want” to gain electrons. It takes energy to remove valence electrons from an atom and form a positive ion. Energy is released when an atom gains valence electrons and forms a negative ion
Desertification:Desertification is a type of land degradation in drylands in which biological productivity is lost due to natural processes or induced by human activities whereby fertile areas become increasingly arid.
Deforestation: the action of clearing a wide area of trees.
Climate change: Climate change describes a change in the average conditions — such as temperature and rainfall — in a region over a long period of time. NASA scientists have observed Earth's surface is warming, and many of the warmest years on record have happened in the past 20 years.
Extinction:
the state or process of being or becoming extinct.
Answer:
5.77 g
Explanation:
Amount of calcium sulfide = 0.0800 mol
Molar mass of calcium sulfide = 72.1 g/mol
Mass of calcium sulfide = 0.0800 mol x 72.1 g/mol
= 5.77 g
