Lavoisier would have taken mercury and heated it up to 350 degrees centigrade in air and then found that a new compound was formed a red or yellow mineral which would be mercury oxide so the experimental observation would be the change in color of the mercury and the formation of a mineral with different properties from pure mercury.
The answer to this question is D have a nice day
The answer is the letter C i think
Answer: the low air pressure reducing CO2 solubility
The differences between the airplane and standard cruising altitude are air pressure. When you are on the higher ground, the air pressure should be lower since there is less air above your head.
In a place with less air pressure, the gas solubility will decrease. Bubbles appeared if gas solubility is lower than the gas concentration. Assuming the beverage concentration is same, then it will be much more bubble appeared in an airplane because the gas solubility is lower.
