When adjusted for any changes in δh and δs with temperature, the standard free energy change δg∘t at 2400 k is equal to 1.22×105j/mol, then the equilibrium constant at 2400 k is 2.21×10−3. The answer to the statement is 2.21×10−3.
Answer:
The final temperature of the system is 27.3°C.
Explanation:
Heat lost by aluminum = 3.99 × 0.91 × (100-T)
= 3.631 (100-T)
Heat gained by water = 10 × 4.184 × (T-21)
= 41.84 (T-21)
As,
Heat gained = Heat loss
or, 3.631(100-T) = 41.84(T-21)
or,363.1 - 3.631 T = 41.84 T - 878.64)
or, (41.84+ 3.631) T = 878.64 +363.1
or T= 
or, T = 27.3°C
Hence the final temperature is 27.3°C.
<span>Igneous
rocks are those rocks that were formed through cooling and solidifying the
molten materials. The best example for igneous rock is solid volcanic java.
Lava are liquid that comes from a volcano, but once it is dried and solidify,
it becomes a rock and called igneous rock.
Another example is the granite and basalt. And according to research igneous
rock comes from the latin word ignis which means fire. Thus this says it all.
From a liquid becomes a rock.
