Justin mixed two clear liquids together during an experiment and made the following observations: The mixed liquids decreased in

temperature without any refrigeration or other action to change the temperature. The color of the liquid changed to blue. Which statement best describes Justin’s experiment? A. A physical change occurred, and this caused the liquid’s chemical properties to change. B. A chemical change occurred, and this caused the liquid’s physical properties to change. C. A physical change occurred, so only physical properties changed. D. A chemical change occurred, so only chemical properties changed.

Answer:

B

Explanation:

A chemical change occurred, and this caused the liquid’s physical properties to change.

when we read her experiment we can see that color changed to blue, it is because new products are formed. And the temperature cause this.

The decomposition of methanol, ch3oh(g), to form ch4(g) and o2(g) absorbs 252.8 kj of heat per mole of oxygen formed. write a ba
Svetllana [295]
The thermochemical equation is the chemical equation including the net change of enthalpy (heat).

The chemical equation for the decomposition of methanol to form methane and oxygen is:

2CH3OH --> 2CH4 + O2

The thermochemical equation is:

2CH3OH ---> 2CH4 + O2  - 252.8 kJ

Note that the heat is placed as negative at the right side because it is absorbed during the decomposition, so the environment will have 252.8 kJ less per each mole of O2 produced.

You can equivalently write:

2CH3OH + 252.8 kJ --> 2CH4 + O2
