Assuming the complete question is;
Consider the balanced equation below;
4NH3 + 3O2 = 2N2 +6H2O
What is the mole ratio of NH3 to N2;
From the balanced equation; the mole ratio of NH3 to N2 is 4:2.
The mole ratio is the ratio of moles of one substance to the number of moles of another substance in a balanced equation. In the above equation; 4 moles of ammonia requires 3 moles of oxygen to produce two moles of nitrogen and six moles of water.
Answer:
The history of water supply and sanitation is one of a logistical challenge to provide clean water and sanitation systems since the dawn of civilization. Where water resources, infrastructure or sanitation systems were insufficient, diseases spread and people fell sick or died prematurely.
Explanation:
<span>Chemicals like HCL should be immediately washed off. HCL is caustic to the skin and will cause the skin to dissolve. While dilute HCL solutions found in secondary school classrooms are unlikely to cause immediate burns, hydrochloric acid is extremely acidic and will leave permanent scars before very long</span>
Answer:
Ionic bond is the electrostatic attraction among the positive and negative ions.
Explanation:
It forms when the valance electrons (electrons in the outer shell) of one atom are transferred to another atom.
