In an undisturbed sequence of layers of rocks, the younger layers lie on top of the older layers
Answer:
Mass = 51 g
Explanation:
Given data:
Mass of nitrogen = 41.93 g
Mass of ammonia formed = ?
Solution:
Chemical equation:
N₂ + 3H₂ → 2NH₃
Number of moles of nitrogen:
Number of moles = mass/molar mass
Number of moles = 41.93 g/ 28 g/mol
Number of moles = 1.5 mol
now we will compare the moles of nitrogen and ammonia.
N₂ : NH₃
1 : 2
1.5 : 2/1×1.5 = 3 mol
Mass of ammonia formed:
Mass = number of moles × molar mass
Mass = 3 mol × 17 g/mol
Mass = 51 g
Answer:
Please take this hepful hint :
F = m * a
6.2 = 2.3 * a
a = 2.7 m/s^2
Explanation:
The arrow doesn’t “point” to anything really, it means that the reactants form (or change) into the products.
