Given :
A balanced chemical equation :
To Find :
How many grams of zinc are needed to produce 12 grams of zinc chloride.
Solution :
Moles of 
,
Now, by balanced chemical equation we can say that 1 mol of Zn produce
1 mol of .
So, 0.088 mol of Zn is required to produced 0.088 mol of .
Therefore, 5.8 grams of zinc is required.
Hence, this is the required solution.
I'd say that it will shift to the left because HCl will provide additional H+ ions which are present on the right side of the equation. Higher concentration of reagents on the one side - chemical equilibrium moves to the opposite side (le chatelier's principle)
Density (p) is defined as the mass (m) per unit volume (v) or:
p = m/v
Using this relationship, the volume is:
v = m/p
Using the given values of mass of 80 grams and density of 8 g/cm3, the sample volume is:
v = 80 grams/8 grams/cm3
v = 10 cm3
The final answer is 10 cm3.
Answer:
It goes the crust mantle outer core and inner core. The crust is what we are standing on it has dirt, rock, stone, the mantle it has lots of silicate rocks and magnesium. The outer core has liquid nickel and iron and the inner core has solid metals
