Answer : The final temperature of the metal block is,
Explanation :
As we know that,
.................(1)
where,
q = heat absorbed or released
= mass of aluminum = 55 g
= mass of water = 0.48 g
= final temperature = ?
= temperature of aluminum =
= temperature of water =
= specific heat of aluminum =
= specific heat of water=
Now put all the given values in equation (1), we get
Thus, the final temperature of the metal block is,
It’s atomic mass is what the number means.
Answer:
Na = 32.4% , % S = 22.6% and %O = 45.0%
Explanation:
% Na = 3.4/10.5. × 100%
= 32.4%
%S = 2.37/10.5 × 100%
= 22.6%
% O= 4.73/10.5 × 100%
= 45.0%xplanation:
