Answer:
3.8*10^2J/(g°C),
Step-by-step explanation:
Heat Energy = mcΔt
23.6 = 5c(35-22.6)
23.6 = 5c(12.4)
23.6 = 62c
c = 23.6/62
c = 0.3806
c = 3.8*10^2J/(g°C),gold
Hence the specific heat of the metal is 3.8*10^2J/(g°C),
Since we are given that y is directly proportional to x and that when y = 11, x equals 6, we can set up a proportion. Before doing that however, we need to note that the question is asking for the value of y when x = 9. Here is the equation:
Now, just cross multiply and solve for y to get a value of 16.5. Therefore, the value of y when x = 9 is
16.5. Hope this helped and have a phenomenal day!
