A blacksmith is in the process of making iron horse shoes. Each shoe, mass of 255.15g, is heated to a bright red (816c), hammered into shape, and then dropped into water to cool. If the bucket contains 4L of water (4000g) initially at room temperature (23c) what will the final temperature of the iron be? Specific heat of cast iron: 0.461 J/gC. Specific heat of water: 4.18 J/gC

Explain

The Akautski is now assembled

- 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
