Consider a 100 kw fuel cell power plant that is fueled with natural gas that has a lower heating value of 48.3 mj/kg. based on the lower heating value of the fuel, the power plant has a heat rate of 7500 btu/kwhe. the fuel cell is a combined heat and power (chp) plant which produces 200,000 btu/h of heat energy at rated power. assume natural gas has a carbon content of 70% (wt). how much co2 is produced per mwhe if only the electrical power is used and the heat is discarded (kgco2/mwhe)?

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms

diaria maybe go see a doctor about that
