Fossils can not be formed in igneous rock because before it cooled from the liquid magma state, any renants of fossils would be destroyed and melted... they form in sedimentary because thats where they can be buried and perserved the easiest, metamorphic would destroy them from the pressures and temperatures involved in there formations
B.) Gravitational force decreases.
You were right !!
Answer:
I would say w is the answer
Answer:
Percentage yield is 41.21%
Explanation:
Equation of reaction,
N₂ + 3H₂ → 2NH₃
Actual NH3 = 6.83g
Mass of N2 = 5.77g
Theoretical yield = ?
5.77g of N2 = 6.83g of NH3
14g of N2 = xg
X = (14 × 6.83) / 5.77
X = 95.62 / 5.77
X = 16.57g of NH3
Theoretical yield of NH3 is 16.57g
Percentage yield = (actual yield / theoretical yield) × 100
% yield = (6.83 / 16.57) × 100
% yield = 0.4121 × 100
% yield = 41.21%
The percentage yield of NH3 is 41.21%
