The specific heat capacity of copper metal : 0.390 J/g °C
<h3>Further explanation</h3>
Given
25 g metal
Δt metal = 18°C
15 g water
Δt water = 2.8 °C
Required
The specific heat capacity of copper metal
Solution
Q out = Q in
Q releases by metal = Q absorbed by water
m.c.Δt metal = m.c.Δt water(c water = 4.184 J/g °C)
25 x c x 18 = 15 x 4.18 x 2.8
c = 0.390 J/g °C
They are all in the same family
Answer:
I know you probably don't need the answer now but here ya go :P
Explanation:
Potassium chloride, makes a purple flame, the metal in Potassium chloride is called potassium (if it's not obvious) the non-metal element in Potassium chloride is chloride.(again duh XD) Last but not least, Potassium spectra in the 700–7000 cm-^1 domain: Transitions involving f-, g-, and h-states!
TA-DA! You now have a decent answer that most likely is right because i'm not good at science at all!
It is d. It is a form of energy that can travel through space. For example, we receive the heat from the sun, which is located very far from the earth via radiation. The sun's heat is not transmitted through any solid medium, but through a vacuum. This is possible by electromagnetic waves.
Answer:
pH=2.3
Explanation:
One H2SO4 molecule produce two H+ ions.
So conc. of H+ = 2(0.0025)
=0.005
Now, pH=-log (conc. of H+)
=-log(0.005)
=2.3
