Answer:
When temperature increases the volume decreases too
Explanation:
In chemical read tion when the temperature increase it compress the volume of the chemical. I can be measured in degree centi grade
<span>Both samples have a mass of 1 g.
Suppose the first sample has a generic mass, X, of 0.34 then it follows that the mass of Y = 1 - 0.34 = 0.66g. So we have a mass ratio of 0.34 : 0.66 where our ratio is of the form X : Y. If we divide by the smallest mass we end up with 1 : 1.94. But Since 1.94 ~ 97/50 then we multiply through by 50, when we do, we end up with a chemical form of the form X50Y97. On the other hand if the sample has a mass of 0.44 of Y then it also follows that the mass of X = 1 - 0.44 = 0.56. So we have a mass ratio of 0.56 : 0.44. If we divide by the smallest mass we end up with 1.27 : 1. Since 1.27 ~ 127/100 then if we multiply through by 100, we end up with a chemical form X127Y100</span>
Answer:
Explanation:
Your telling us do a whole experiment for you just for you to not to do it.
Because a physical change does not change the substance's chemical properties
An example of a chemical reaction like sugar's chemical formula is C6H12O6 and if we apply heat to it and it burns it will now become just carbon ashes C
Answer:
Hey mate.....
Explanation:
This is ur answer.....
<em>Phenolphthalein is often used as an indicator in acid–base titrations. For this application, it turns colorless in acidic solutions and pink in basic solutions. It belongs to the class of dyes known as phthalein dyes.</em>
