In two or more complete sentences explain how to balance the chemical equation and classify its reaction type.
Artemon [7]
<h3>Answer:</h3>

#1. Balanced equation: 2C₅H₅ + Fe → Fe(C₅H₅)₂

#2. Type of reaction: Synthesis reaction

<h3>Explanation:</h3>
  • Balanced equations are equations that obey the law of conservation of mass.
  • When an equation is balanced the number of atoms of each element is equal on both side of the equation.
  • Equations are balanced by putting appropriate coefficients on the reactants and products.
  • In our case, we are going to put coefficients 2, 1 and 1.
  • Thus, the balanced equation will be;

2C₅H₅ + Fe → Fe(C₅H₅)₂

  • This type of a reaction is known as synthesis reaction, in which two or more reactants or compounds combine to form a single compound or product.

The temperature at which the reaction is occurring is increased
svetlana [45]

The addition of heat energy to a system always causes the temperature of that system to increase. This is always true because you are adding heat of a substance to increase  its temperature. For example, you are going to drink a cup of coffee. And you wanted it hot to boost your attention. So you have to use hot water. In order for your water to become hot or warm, you need boil it in a kettle. Note that you are going to use an electric stove. The electric stove gets it energy from the source giving it a hotter temperature to the water in the kettle. You are applying heat energy to warm the water. So, the statement is true.

A photon has 8.0 × 10–15 J of energy. Planck’s constant is 6.63 × 10–34 J•s. What is the frequency of the photon
german
The formula is:
frequency * h (Planck's constant) = Energy
So, to find frequency you need just divide energy by the constant:
frequency = (8 * 10^-15 J) / (6.63 * 10^-34 J*s) = 1.2 * 10^19 1/s or 1.2 * 10^19 Hz
