Answer:
The answer is 3.87 J/g°C
Explanation:
Here is the equation we are going to use:

C= specfic heat in J/g°C
q = heat in joules (J)
m = mass in grams (g)
T = change in temperature
Here is what is given:
q = 849 J
m = 95.4 g
T = 48.0 - 25.0 = 23°C
Find:
Specific heat capacity in J/g
The first thing we are going to do is plug everything into the equation:

Then we are going to solve for C

Hg<span> is the modern </span>chemical symbol for mercury<span>. It comes from hydrargyrum, a Latinized form of the Greek word ὑδράργυρος (hydrargyros), which is a </span>compound<span>word meaning "water-silver" (from ὑδρ- hydr-, the root of ὕδωρ, "water," and ἄργυρος argyros "silver") – since it is liquid like water and shiny like silver.</span>
One reason may be that iron is a much heavier metal, and a much better conductor of heat and electricity. Iron would lead to some issues after a while, and repairs may end up costing more than it would have cost to just buy aluminum in the first place.
So, basically just because of each one's different ability to conduct heat and electricity.
Sodium acetate is a type<span> of salt. When water is added to sodium acetate, the chemical bonds break down, causing it to separate into sodium ions and acetate ions. </span>
