Answer: The mole ratio of hydrogen to nitrogen is 3 mole: 1 mole, 3:1
Explanation:
•Mole ratios are determined using the coefficients of the substances in the balanced chemical equation. •Each coefficient represents the number of mole of each substance in the chemical reaction.
•The mole ratio can be determined by first writing out a balanced chemical equation for the reaction.
For this reaction the balanced chemical equation is
N2(g) + 3H2(g) ----> 2NH3(g)
1mol:3mol : 2mol
From the equation we can see that 1 mole of N2(g) reacts with 3 moles of H2(g) or 3 moles of H2(g) react with 1 mole of N2(g) to produce 2 moles of NH3(g).
Therefore, the mole ratio of hydrogen to nitrogen is 3 mole: 1 mole, 3:1
<span>Lithium atoms have one valence electron, where as oxygen atoms have six. Lithium atoms tend to give up their single valence electrons, and oxygen tends to gain two valence electrons from other atoms, like lithium. They do this so they will have filled valence shells. hope this answers your question :)</span>
Hello!
To find the acceleration given the net force (N) and the mass (kg), we will need to use Newton's Second Law of Motion, which is shortened to be F = ma.
In this formula, F is the net force, m is the mass, and a is the acceleration.
Since we are given the net force and mass, we will be using division to find the acceleration, which is measured as m/s².
1). Net Force: 5.0 N; Mass = 2.5 kg
5.0 N / 2.5 kg = 2.0 m/s²
2). Net Force: 2.32 N; Mass = 12 kg
2.32 N / 12 kg ≈ 0.19 m/s²
3). Net Force: 18.2 N; Mass: 1.967 kg
18.2 N / 1.967 kg ≈ 9.25 m/s²
4). Net Force: 0.87 N; Mass: 21.2 kg
0.87 N / 21.2 kg ≈ 0.04 m/s²
5). Net Force: 180 N; Mass: 1.793 kg
180 N / 1.793 kg ≈ 100.39 m/s²
<u>Final answers</u>:
- 2.0 m/s²
- 0.19 m/s²
- 9.25 m/s²
- 0.04 m/s²
- 100.39 m/s²
Answer:
The Pauli Exclusion Principle
Explanation:
The Pauli Exclusion Principle states that, in an atom or molecule, no two electrons can have the same four electronic quantum numbers. As an orbital can contain a maximum of only two electrons, the two electrons must have opposing spins.
