1. At 293 K, the solubility of KCl is 34 g/100 g of H20. In the laboratory, a student mixes 75
g KCl with 200 g of H. O at a temperature of 293 K. How much of the KCl will dissolve? Is
the solution saturated or unsaturated? What is the mass of any solid KCl left undissolved
on the bottom of the container?

- 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

can you list the answers so i can answer

idk what is it? is this a question that you know the answer or u dont
