Breaking glass is an example of a physical change because if you break it, it is still glass.
Answer:
All matter is in continual random motion.
Explanation:
Because Kinetic Molecular theory is based on a principle idea that tiny particles such as gas particles are always in motion.
Answer:
I believe the ans is 2)FeO and 3)Cl2
Answer:
The correct answer is 29 grams.
Explanation:
Based on the given question, the reaction will be,
CH3CH=CHCH3 + H2 ⇒ CH3CH2CH2CH3
The molecular weight of butene is 56 grams per mole, and the molecular weight of butane is 58 grams per mole.
Thus, it can be said that 56 grams of butene reacts with hydrogen gas and produces 58 grams of butane.
Therefore, 28 grams of butene when reacts with hydrogen gas to give,
= 58/56 * 28 = 29 grams of butane.
Hence, the mass of butane produced will be 29 grams.
