A 0.316 mol 0.316mol0, point, 316, start text, m, o, l, end text sample of nitrogen gas, N 2 ( g ) N 2 (g)start text, N, end text, start subscript, 2, end subscript, left parenthesis, g, right parenthesis, is placed in a 4.00 L 4.00L4, point, 00, start text, L, end text container at 315 K 315K315, start text, K, end text. What is the pressure, in Torr Torrstart text, T, o, r, r, end text, of the nitrogen gas? Express the answer using 3 significant figures.

- 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
