Which has a lower freezing point ice or ice cream?

Ice cream will have lower freezing point than ice. this can be understood with the concept of freezing point depression, which is a colligative property. Colligative properties are those which depends upon number of solvent/ solute particles. Ex: elevation in boiling point , osmotic pressure. If we add a nonvolatile solute in a solvent, its freezing point decreases.  In case of ice cream we add sugar which lowers its freezing point, aa sugar is a non volatile solute.

- 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

sorry i was late, but i don't know what assignment your talking about, i'm in flvs as well, im in earth space science. but u are behind pace bc every class should be in the 3's or 4'
