Answer:
1.533 moles Au
Explanation:
To find the moles from atoms, you just use Avogadro's number (6.02214076×10^23 mol^-1) and divide by it. Hope this helped!
Answer:
Hg, Tl, Pb, Bi.
Explanation:
The elements that are all in the same period are: Hg, Tl, Pb, Bi.
Kindly, find the attached image that show that all elements are in period 6.
Rb, Sr, La, Zr
:
All are in period 5 except La is in period 6.
Al, Ga, Si, P
:
All are in period 3 except Ga is in period 4.
N, O, Cl, Br:
N, and O are in period 2. While Cl is in period 3 and Br is in period 4.
Answer:
The system will shift to the right (Forward).
Explanation:
Based on the equilibrium:
2CO(g) + O2(g) ⇄ 2CO2(g)
If the amount of O2 is increased: The equilibrium will shift to the right trying to decrease this concentration following the Le-Ch principle that says:
A change in an equilibrium will be counteracted by the system producing a response that restore the initial state.
Answer:
Darwin's book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution.
Answer:
The specific heat of the alloy
Explanation:
Mass of an alloy = 25 gm
Initial temperature = 100°c = 373 K
Mass of water = 90 gm
Initial temperature of water = 25.32 °c = 298.32 K
Final temperature = 27.18 °c = 300.18 K
From energy balance equation
Heat lost by alloy = Heat gain by water
[ - ] = ( - )
25 × × ( 373 - 300.18 ) = 90 × 4.2 (300.18 - 298.32)
This is the specific heat of the alloy.
