B. providing a moderate, livable climate. The atmosphere basically means the canopy that shields us. If it isnt moderate or doesnt have livable climate, I dont think we would be able to survive. :|
Answer:
The correct choices are:
- <em>using accurate measurements</em>
- <em>using pure chemicals</em>
- <em>performing the reaction under the most ideal conditions</em>
Explanation:
The theoretical yield is the maximum amount of product that could be obtained by the chemical reaction, from a given amount of reactants. You calculate the theoretical yield using the stoichiometry coefficients of the balanced chemical equation.
The <em>percent yield </em>is the ratio of the actual yield (the actual amount obtained) of a product to the theoretical yield for the same product, expressed as a percentage (i.e. multiplied by 100).
- percent yield = actual yield × 100 / theoretical yield
As the actual yield decrease (the numerator of the ratio), the percent yield decrease.
To increase the percent yield it is important:
- using accurate measurements
- performing the reaction under the most ideal conditions
<em><u>Using accurate measurements:</u></em> if you do not add the correct amounts of each reactant, then the product obtained will not be what you can predict from the theoretical calculations and you will be wasteing one or other reactant, without reaching the maximum yield possible.
<em><u>Using pure chemicals:</u></em> if the chemicals are not pure, the amount of actual reactants will be lower than they should be, leading to a lower actual yield.
<em><u>Performing the reaction under the most ideal conditions:</u></em> the actual rate of reactions depend on the conditions: temperature and pressure are the most commons. Since, temperature and pressure may change that rate of reactions, you should find and use the most ideal conditions to get the greatest actual yield.
<em>Adding water</em>, can just dilute the reactants and would decrease the rate of reaction, which would not be helpful to increase the yield.

<h3>The following compound is CH3 CH3 CH2 CH2 CH2 CH3, but what is its IUPAC name?</h3>
Answer and justification A longest carbon chain in the above diagram has seven carbon atoms, as can be observed.The IUPAC nomenclature for this compound is heptane since all of the bonds are single bonds devoid of any functional groups.
<h3>What is this compound's IUPAC name, CH3 CH2 CH2 CH2 CH2 CH?</h3>
When there are nine carbons, the word non is the root.Therefore, nonane is the IUPAC term for CH3-CH2-CH2-CH2-CH2-CH2-CH2-CH3.
