Answer:
1.4 g H₂O
Explanation:
In a reaction, the reactants are usually not present in exact <em>stoichiometric amounts</em>, that is, <em>in the proportions indicated by the balanced equation</em>. Frequently a large excess of one reactant is supplied to ensure that the more expensive reactant is completely converted to the desired product. Consequently, some reactant will be left over at the end of the reaction. T<em>he reactant used up first in a reaction</em> is called the <em>limiting reagent</em>, because <u>the maximum amount of product formed depends on how much of this reactant was originally present</u>. When this reactant is used up, no more product can be formed.
Answer:
the relative height of M⁺ : M+1 is; 0.7418 : 0.2228
The relative heights are; In order of increasing mass 100 : 30
Explanation:
Given the data in the question;
The M⁺ peak comes from all ¹²₆C atoms
so, the probability in cholesterol, C₂₇H₄₈O is ( 98.9% )²⁷ = ( 0.989 )²⁷ = 0.7418
The M+1 peak comes from the isotopic carbon ¹³₆C.
so, the probability in cholesterol is ⇒ 1.10% × ( 98.9% )²⁶ = 0.011 × ( 0.989)²⁶
The probability for 27 carbons is ⇒ 27 × 0.011 × ( 0.989)²⁶ = 0.2228
Therefore, the relative height of M⁺ : M+1 is; 0.7418 : 0.2228
The relative heights are; In order of increasing mass 100 : 30
<h2>Answer:</h2>
An increase in the population of prey means more food for predators, which will<u> increase</u> the predators' population. As a result, many more prey will be hunted, causing the prey population to<u> decrease.</u> In response, the predator population will <u>decrease</u>, resulting in an increase in the prey population.
<h3>Explanation:</h3>
The feedback loop is control of the system containing the prey and predator.
In this loop, the population of predator is directly proportional to prey but the population of prey is inversely proportional to a predators population.
As the population of prey increases, the population size of predator becomes large due to the availability of food. This inversely decreases the population of prey, as the predator do more hunt.
So the decrease in prey population results in a decrease in the predator population.
