A sample of 11.0g of sodium is reacted with 18.6g of water to produce sodium hydroxide and hydrogen gas. Using the balanced equation below, predict which is the limiting reactant and the maximum amount in moles of hydrogen gas that can be produced.

hi,

the answer is d, it has indefinite shape but definite volume.

hope this !

neutrons are in the middle of the atom and the electrons, which are much smaller.

- 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
