3. Analizando la siguiente reacción química de formación del agua: 2 H2 (g) + O2 (g)  2 H2O (l)

Si se hacen reaccionar 10 g de hidrógeno con 10 g de oxígeno:

a) Plantee las razones molares de dicha ecuación
b) Determine si se consumen la totalidad de dichos reactivos. Demuéstrelo con los cálculos estequiométricos correspondientes.

- 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
