15000 joules is used to heat a 950g piece of metal from 45 degrees Celsius to 78 degrees Celsius what is the specific heat of th
is metal
1 answer:
Answer:
0.478 J/g/C
Explanation:
When solving questions on heat energy, we can use the formula
Q = mcT where
Q is the amount of energy supplied in Joules
m is the mass of the object in Grams
c is the specific heat capacity of the metal in Joules Per Gram Per Degree Celcius
T is the <em>c</em><em>h</em><em>a</em><em>n</em><em>g</em><em>e</em><em> </em>in Temperature in Degree Celcius.
So by applying the formula to this question, we get:
15000 = (950)(c)(78 -45)
c = <u>0.478 J/g/C</u>

Answer:150g of gold
Explanation: There is a lot more gold and gold is significantly significantly more dense than lithium
The dissociation equation will be
NH4OH ---> NH4+ + OH-
Initial 0.006 0 0
Change -0.006 X 0.053 +0.006 X 0.053 -0.006 X 0.053
Equlibrium 0.006 -0.006 X 0.053 0.006 X 0.053 0.006 X 0.053
Ka = [NH4+] [ OH-] / [NH4OH] = (0.006 X 0.053)^2 / 0.006 -0.006 X 0.053
Ka = 1.78 X 10^-5
