If both objects have the same volume, but a different weight, than the densities are different. One has the greater density, while the other doesn't.
Redox reactions consist of reduction and oxidation reactions
oxidation reactions are the giving out of electrons, the oxidation number of the species giving out the electrons increases during oxidation
reduction reactions are taking in electrons and the oxidation number of the species taking in electrons reduces after reduction
in the reaction Ca + Cl₂ --> CaCl₂
oxidation numbers of Ca in Ca - 0 and CaCl₂ - +2
oxidation numbers of Cl in Cl₂ - 0 and CaCl₂ - -1
oxidation number of Ca has increased from 0 to +2 therefore Ca is oxidised
Answer:
A. A double bond
Explanation:
Trans and cis Isomerism is a form of isomerism that specifically refers to alkenes, which is to say, aliphatic chains containing a <em>double bond</em> between two carbon atoms. Technically speaking, options B. and C. are both correct, because an alkene contains aliphatic hydrocarbons. However, neither of those options necessarily relate to cis and trans isomers.
Answer:
<h2>The answer is 1.48 L</h2>
Explanation:
In order to find the original volume we use the same for Boyle's law which is

where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we are finding the original volume

From the question
P1 = 172 kPa = 172000 Pa
P2 = 85 kPa = 85000 Pa
V2 = 3 L
We have

We have the final answer as
<h3>1.48 L</h3>
