Answer: 2.64 g of carbon dioxide that could be produced by the chemical reaction.
Explanation:
To calculate the moles :
According to stoichiometry :
1 mole of 
require = 2 moles of 
Thus 0.06 moles of will require=
of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 1 moles of give = 1 mole of 
Thus 0.06 moles of give =
of
Mass of 
Thus 2.64 g of carbon dioxide that could be produced by the chemical reaction.
The most generally accepted form of conclusive evidence for the theory of Evolution is the fossil record.
<h3>What is the theory of Evolution?</h3>
- The theory of evolution was proposed by Charles Darwin.
- It states that as time passes, organisms evolve to better adapt to their environments.
- This is closely related to natural selection, which is considered a <em><u>driving force of </u></em><em><u>evolution</u></em><em><u>. </u></em>
<h3>How the fossil record supports this theory</h3>
- The fossil record provides essential data to support this claim.
- The data comes in the form of the comparison between fossils of two closely related organisms, separated by a matter of generations, that <em><u>present changes in the genetic code that made them more apt for survival.</u></em>
Therefore, we can confirm that the most generally accepted form of conclusive evidence for evolution is the presence of <u>fossils </u><u>that show the genetic correlation between two organisms and the progression of </u><u>evolution </u><u>between them. </u>

Explanation:
Step one look for the longest chain of carbon atoms
Longest chain is 7 C atoms
Step 2 look for double bonds or others functional groups
it is present in 3rd carbon
Therefore IUPAC name is 3-heptene
From point of stereochemistry it can also be written as trans-3-heptene as the hydrogens are placed in opposite side of the C=C bond.

Answer:
the median is 14 the range is 15 the mode is 14 and the mean is 12.7
Explanation:
for the median you put all numbers is order but least to greatest and figure out the middle number for range you take the smallest and the biggest number and subtract them for mode you use the most repeated number and for the mean you add all the numbers and divide by the total of numbers I hope this helped
In the given reaction fluorine is reduced and chlorine is oxidized.
<h3>What is oxidation and reduction?</h3>
Oxidation is a process in which addition of oxygen or removal of hydrogen and electron takes place, while reduction is a process in which addition of hydrogen & electrons or removal of oxygen takes place.
Given chemical reaction is:
F₂ + 2HCl → Cl₂ + 2HF
- In the above reaction fluorine is reduced as it accepts an electron and increase in it its oxidation state takes from 0 to -1, which shows reduction.
- In the reaction chlorine is oxidized as it losses an electron and decrease in its oxidation state takes from -1 to 0, which shows oxidation.
- Oxidation half reaction is:
F₂ + 2e⁻ → 2F⁻
- Reduction half reaction is:
2Cl⁻ → Cl₂ + 2e⁻
Hence, fluorine is reduced and chlorine is oxidized in the given reaction.
