The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

1. Balance the following reaction:<\/strong>
C\u2083H\u2087OH + O\u2082 \u2192 CO\u2082 + H\u2082O<\/strong><\/p>\n\n\n\n

Balanced equation:
C\u2083H\u2087OH + 4.5 O\u2082 \u2192 3 CO\u2082 + 4 H\u2082O<\/strong>
To eliminate the decimal, multiply all coefficients by 2:
2 C\u2083H\u2087OH + 9 O\u2082 \u2192 6 CO\u2082 + 8 H\u2082O<\/strong><\/p>\n\n\n\n

\n\n\n\n

2. Balance the following reaction:<\/strong>
CH\u2084 + O\u2082 \u2192 CO\u2082 + H\u2082O<\/strong><\/p>\n\n\n\n

Balanced equation:
CH\u2084 + 2 O\u2082 \u2192 CO\u2082 + 2 H\u2082O<\/strong><\/p>\n\n\n\n

\n\n\n\n

3. In the equation above, 31.2 kJ of energy is released for every gram of methane burned. How much energy is released if 4,500 grams of methane is burned?<\/strong><\/p>\n\n\n\n

Energy released = 31.2 kJ\/g \u00d7 4,500 g = 140,400 kJ<\/strong><\/p>\n\n\n\n

Answer: 140,400 kJ of energy<\/strong> is released when 4,500 grams of methane is burned.<\/p>\n\n\n\n

\n\n\n\n

4. Balance the following reaction:<\/strong>
Al + AgNO\u2083 \u2192 Ag + Al(NO\u2083)\u2083<\/strong><\/p>\n\n\n\n

Balanced equation:
2 Al + 6 AgNO\u2083 \u2192 6 Ag + 2 Al(NO\u2083)\u2083<\/strong><\/p>\n\n\n\n

\n\n\n\n

5. Oxidation and Reduction half-reactions:<\/strong><\/p>\n\n\n\n

Overall equation:<\/strong>
Al + 3 Ag\u207a \u2192 3 Ag + Al\u00b3\u207a<\/strong><\/p>\n\n\n\n

    \n
  • Oxidation half-reaction:<\/strong>
    Al \u2192 Al\u00b3\u207a + 3e\u207b<\/strong><\/li>\n\n\n\n
  • Reduction half-reaction:<\/strong>
    3 Ag\u207a + 3e\u207b \u2192 3 Ag<\/strong><\/li>\n<\/ul>\n\n\n\n
    \n\n\n\n

    When I use energy, I can be a faithful steward of the earth’s resources by using it wisely and minimizing waste. For example, I will turn off lights and appliances when not in use, choose energy-efficient devices, and support renewable sources like solar or wind power. By doing these things, I reduce the amount of fossil fuels burned, which helps limit greenhouse gas emissions and air pollution. Being mindful of energy use protects the environment and preserves natural resources for future generations. It also shows respect for the Earth, which is a gift we have a responsibility to care for. Using energy responsibly reduces the strain on ecosystems and supports a healthier, more sustainable planet.<\/p>\n\n\n\n
