Answer:
Explanation:
Hello there!
In this case, since the density of the metal is computed as shown below:
We need to calculate the volume of the solid by subtracting the final volume and the initial volume of water:
Thus, we obtain:
Best regards!
The chemical transformation of a carbon-carbon double bond is by addition reaction. The statement best describes the driving force is that the reaction is favorable because the total bond strength in the products is greater than in the reactants.
- A great number of reagents often found in inorganic and organic, have been known to add to the functional group of alkenes.
The bond energies of a molecule is simply known as the energies needed to break all the covalent bonds in the molecule.
When the bond energies of the product molecules is known to be greater than the bond energies of the reactants, the reaction is regarded as exothermic.
The full question is below
Which statement best describes the driving force behind the electrophilic addition of strong acid to an alkene?
The reaction is favorable because the pi bond is stronger than a sigma bond and it takes more energy to break it.
The reaction is favorable because a less stable, high-energy intermediate is formed.
The reaction is favorable because the first step is the rate-determining step.
The reaction is favorable because the total bond strength in the products is greater than in the reactants.
The reaction is favorable because the overall reaction is endothermic.

Answer:
D. All of the above
Explanation:
E = MC² is a common equation in physics.
E is energy
M is mass
C is the speed of light
The law was stated by Albert Einstein.
- From this law, it was shown that energy is released when matter is destroyed.
- Mass and energy are equivalent as seen in nuclear reactions where mass is converted to energy.
- Mass and energy is usually conserved in any process and this is a subtle modification of the law of conservation of matter and energy.
- Most of these postulates apply to nuclear reactions which generally do not follow some precepts of chemical laws.
Answer:
A. They are isotopes.
Explanation:
An isotope is an element with the same number of protons but different number of neutrons resulting in a varied mass number/molecular weight.
