You can use a universal indicator. The color of the universal indicator before contact with other chemicals is green, which is the pH of 7. We know that bottled water is pH 7. So when we put a few drops of universal indicator, the color would be green indicating neutral pH.

Arguments in favor of renewable energy

I actually did the math for this a while ago. In order to install solar panels to every house in America it would cost a one time payment of about 900 billion dollars. We spend 700 billion on fossil fuels each year so in two years it would already pay itself off them we'd actually profit from it. Even if you don't believe in global warming you can't argue with that.

1.For the first ten reactions, write a balanced reaction for each tube in which a reaction occurred. If there was no reaction, w
slamgirl [31]

The equations of reaction occurring in the tubes are as follows:

  • 2 MnO₄⁻ + 6 Br⁻ + 8 H⁺ → 2 MnO₂ + 3 Br₂ + 4 H₂O
  • 2 MnO₄⁻ + 6 I⁻ + 8 H⁺ → 2 MnO₂ + 3 I₂ + 4 H₂O
  • No reaction
  • 2 Fe³⁺ + 2 I⁻ → 2 Fe²⁺ + I₂

<h3>What are the reactions occurring in the tubes?</h3>

The reactions occurring in the tubes are redox reactions.

Based on the table the equations of reaction are as follows:

  • 2 MnO₄⁻ + 6 Br⁻ + 8 H⁺ → 2 MnO₂ + 3 Br₂ + 4 H₂O
  • 2 MnO₄⁻ + 6 I⁻ + 8 H⁺ → 2 MnO₂ + 3 I₂ + 4 H₂O
  • No reaction
  • 2 Fe³⁺ + 2 I⁻ → 2 Fe²⁺ + I₂

In conclusion, redox reaction are reactions in which electrons are transferred.

What occurs as two atoms of fluorine combine to become a molecule of fluorine?
algol [13]
When two atoms of Florine combines, they share an electron pair to complete it's octet. This result is formation of single bond between two fluorine atoms. This process is exothermic in nature, and hence, heat is liberated during the process of bond formation.  <span />
