Answer:
2H₂ + O₂ → 2H₂O.
Explanation:
- For the reaction of water formation:
<em>2H₂ + O₂ → 2H₂O.</em>
- It should apply the the law of conservation of mass that the no. of reactants atoms is equal to the no. of products atoms.
<em>So, every </em><em>2.0 moles of H₂ </em><em>react with </em><em>1.0 mole of O₂</em><em> to produce </em><em>2.0 moles of H₂O.</em>

The anode in a voltaic cell is the source of electrons so it is considered to be negative. The counterpart is the cathode, which is considered to be positive. If you look at the diagram the electron flow goes from A to B. This means that part A is the anode. Part B is the cathode. Part C and D is the electrolyte.
The answer therefore is the first option.
Answer: The mass of 405 ml of cresol is 415 grams
Explanation:
Density is defined as the mass contained per unit volume.
Given : Density of cresol = 1024 g/L
Volume of cresol = 405 ml = 0.405 L ( 1L=1000ml)
Putting in the values we get:
Thus mass of 405 ml of cresol is 415 grams
