Answer:
2.5 moles of O₂ = 5 moles of H₂O
Explanation:
The balanced equation for the reaction is given below:
2H₂ + O₂ —> 2H₂O
From the balanced equation above,
1 mole of O₂ reacted to produce 2 moles of H₂O.
Finally, we shall determine the number of mole of H₂O produced by the reaction of 2.5 moles of O₂. This can be obtained as follow:
From the balanced equation above,
1 mole of O₂ reacted to produce 2 moles of H₂O.
Therefore, 2.5 moles of O₂ will react to produce = 2.5 × 2 = 5 moles of H₂O.
Thus,
2.5 moles of O₂ = 5 moles of H₂O
In a combustion reaction, one of the reactants is always oxygen.
Answer:
neutrons are inside the nucleus
Explanation:
The most significant contribution that added to Rutherford's discovery of a positive nucleus is that neutrons are also inside the nucleus.
- The discovery of neutrons as a nuclear particle was instrumental to Rutherford's discovery.
- Since during his experiment, the alpha particles were deflected partly, he suggested a massive nucleus made up of just protons.
- With the discovery of the neutron, the mass of the nucleus was enough to cause the deflection.
