Hello there!
In this case, according to the given chemical reaction, it is possible for us to calculate the produced grams of nitrogen monoxide by starting with 25.0 g of nitrogen via their 1:2 mole ratio and the molar masses of 30.1 g/mol and 28.02 g/mol, respectively and by some stoichiometry:

Answer:
0.675 mol
Explanation:
Step 1: Write the balanced equation
2 Al + Fe₂O₃ ⇒ 2 Fe + Al₂O₃
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of Fe to Al₂O₃ is 2:1.
Step 3: Calculate the moles of Al₂O₃ produced when 1.35 moles of Fe are produced
We will use the established molar ratio.
1.35 mol Fe × 1 mol Al₂O₃/2 mol Fe = 0.675 mol Al₂O₃
Answer: 2m/s^2
Explanation:
Velocity of skateboard = 20.0 m/s.
Time taken = Ten seconds (10 s)
Acceleration = ?
Recall that acceleration is the change in velocity of a body per unit time.
i.e Acceleration = (velocity / Time)
Acceleration = 20.0m/s ➗ 10 s
Acceleration = 2m/s^2
Thus, Jeffrey acceleration was 2m/s^2
Answer:
Electron microscopes differ from light microscopes in that they produce an image of a specimen by using a beam of electrons rather than a beam of light. Electrons have much a shorter wavelength than visible light, and this allows electron microscopes to produce higher-resolution images than standard light microscopes.
