Answer:
1.4063 moles of oxygen are required
Explanation:
Based on the chemical equation:
4Al + 3O₂ → 2Al₂O₃
<em>4 moles of aluminium react with 3 moles of oxygen.</em>
<em />
To solve this question we need to convert the moles of aluminium to moles of oxygen using the chemical reaction:
1.875 moles Al * (3 moles O₂ / 4 moles Al) =
<h3>1.4063 moles of oxygen are required</h3>
If an atom has 3 energy levels it should have 3 sublevels
C
because the mass never changes, it is always equal on both sides.
Answer:
1. HNO3
2. HNO2
Explanation:
Nitrogen acid may refer to any of:
1. Nitric acid, HNO3 or
2. Nitrous acid, HNO2
Acid rain is caused by a chemical reaction that begins when compound like nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain. nitrogen oxides dissolve very easily in water and can be carried very far by the wind. As a result, the compounds can travel long distances where they become part of the rain, sleet, snow, and fog as acids.
Equation of reaction:
NO2 + H2O ==> HNO3
NO + H2O ==> HNO2
Answer:
If they are pushing off the wall, it would be B, as they are going faster. If they are slowing down, it would probably be A, gradually getting slower.
