KI (s)  ----\ \textgreater \     K(s)  + I_2 (g)

Now, balance the equation:

2KI (s)  ----\ \textgreater \     2K(s)  + I_2 (g)

I_2 in gaseous state exist as a diatomic molecule.

Vikki [24]

D. oxygen is used to break down glucose into energy

Explanation:

During respiration, oxygen is used to break down glucose into energy:

          C₆H₁₂O₆  + O₂   →  CO₂   +  H₂O  + energy

In the process of respiration, oxygen gas combines with glucose to liberate energy.

  • Respiratory system in the body is responsible for the metabolic break down of food to provide energy for the working of the human body.
  • Chemical energy in glucose is broken down to produce other forms of energy most especially heat.
  • The by product is usually carbon dioxide and water vapor.

Bob measured out 1.60 grams of sodium. He calculates that 1.60 g of
saul85 [17]

Answer:

84.8%

Explanation:

Step 1: Given data

Bob measured out 1.60 g of Na. He forms NaCl according to the following equation.

Na + 1/2 Cl₂ ⇒ NaCl

According to this equation, he calculates that 1.60 g of sodium should produce 4.07 g of NaCl, which is the theoretical yield. However, he carries out the experiment and only makes 3.45 g of NaCl, which is the real yield.

Step 2: Calculate the percent yield.

We will use the following expression.

%yield = real yield / theoretical yield × 100%

%yield = 3.45 g / 4.07 g × 100% = 84.8%
