4 OT 5 A 35g chunk of metal at 130C was dropped in a bucket containing 220g of water at 25C. The final temperature of the mixture
was 300. What is the specific heat capacity of the metal?
(Specific heat for water: 4184 J/g C) Formula (m)(c)(T) = (m) (c)(T)

The specific heat capacity of metal is

Explanation:

As we know that,  

where,

= mass of metal = 35 g

= mass of water = 220 g

= final temperature =

= temperature of metal =

= temperature of water =

= specific heat of metal = ?

= specific heat of water =  

Now put all the given values in equation (1), we get

Therefore, the specific heat capacity of metal is

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
