Chemistry
1 answer:
charle [14.2K]3 years ago
4 0

Answer is: a) is has increased.

There are two types of reaction:  

1) endothermic reaction (chemical reaction that absorbs more energy than it releases).

For example, the breakdown of ozone is an endothermic process. Ozone has lower energy than molecular oxygen (O₂) and oxygen atom, so ozone need energy to break bond between oxygen atoms.

2) exothermic reaction (chemical reaction that releases more energy than it absorbs).  

For example, ΔH(reaction) = -225 kJ/mol; this is exothermic reaction.

In a simple distillation setup, what is the sequence of equipment from the bench top to the round bottom flask
Julli [10]

In a simple distillation setup, the sequence of equipment from the bench top to the round bottom flask is:

  • Thermometer
  • Distillation flask
  • Liebig condenser
  • Round bottom flask
  • Bunsen burner

<h3>What is Distillation?</h3>

This is the process in which a mixture is separated through selective boiling and condensation.

The distillation flask and liebig condenser are usually located above the round bottom flask in the set up.

If a compound has a molar más of 180g/mol and it’s empirical formula is CH^2O, what is it’s molecular formula?
lesya [120]

C: 12.0107 g/mol ≅ 12.00 g/mol

H: 1.00784 g/mol ≅ 1.008 g/mol

O: 15.999 g/mol ≅ 16.00 g/mol

n(molar mass of CH2O)= 180

n.30=180

n=6

molecular formula: c6h12o6 glucose
