The number of grams of lead product that would theoretically be produced from the given reaction is; Mass of lead product = 23.6 g
Potassium iodide reacting with Lead(II) Nitrate would yield the balanced equation;
2KI + Pb(NO₃)₂ = 2KNO₃ + PbI₂
2moles : 1 mole = 2 moles : 1 mole
From online tables;
Molar mass of KI = 166 g/mol
Molar mass of Pb(NO₃)₂ = 331.2 g/mol
We are given;
Mass of KI = 17 g
Mass of Pb(NO₃)₂ = 25 g
Thus;
Number of moles of PbI₂ yielded in order to find the limiting reactant will be;
no of moles of PbI₂ from KI = (17g/166 g/mol) × (1 mole of PbI₂/2 mol of KI)
no of moles of PbI₂ from KI = 0.0512 mols
Similarly;
no of moles of PbI₂ from Pb(NO₃)₂ = (25g/331.2 g/mol) × (1 mole of PbI₂/1 mol of Pb(NO₃)₂)
no of moles of PbI₂ from Pb(NO₃)₂ = 0.0755 moles
We can see that KI produced the least amount of moles. Thus;
Mass = 0.0512 * molar mass of PbI₂
From tables, molar mass of PbI₂ = 461 g/mol
Thus;
Mass of lead product = 461 * 0.0512
Mass of lead product = 23.6 g

The time that customers wait to be served at the deli for a grocery store follows the uniform distribution between 0 and 7 minutes. What is the probability that a randomly selected customer will wait more than 4 minutes at the deli?.
The probability that a randomly selected customer will wait more than 4 minutes at the deli is given below
The probability that a randomly selected customer will wait more than 4 minutes = [tex]0.4286[/tex]The waiting time for the customers is uniformly distributed between 0 - 7 minutes
Consider a random variabe X that represents the waiting time of customers and uniformly distributed between 0-7 minutes
Therefore, the density function of X is determined as
[tex]f(x) = \frac{1}{b-a}\\\\f(x) = \frac{1}{7-0}\\\\f(x) = \frac{1}{7}[/tex]
The probability that the customer will wait more than 4minutes,
[tex]P(X>4) = \int\limits^7_4 f{x} \,dx\\\\= \int\limits^7_4 \, \frac{1}{7}dx\\\\= \frac{1}{7} * [x]^7_4\\\\= \frac{7-4}{7} \\\\= 0.4286[/tex]

Answer:
Longitude and Population Density
Explanation:
Longitude
Longitude won't have much effect because it is just across the earth in E to W. (east to west). While, Latitude will affect the Earth because there is something called a Equator, which is USUALLY hot, and the Polar zones, which are mostly Cold.
Population Density
Population Density won't affect much because the amount of carbon dioxide a person produces is pretty less. But yeah, the factories make a lot of more Carbon Dioxide so that is why they will be producing more than the people. But people can't produce so much to warm up their environment.

English nobles resisted peasant demands such as those described in the passage because agricultural labor in many parts of fourteenth-century afro-eurasia had become scarce as a result of which of the following developments?.
Answer: Significant increase in mortality due to the spread of epidemic diseases.
Explanation:
During the 14th century, many parts of Europe and Asia were completely ravaged by an epidemic plague called The Black Death. It was a form of bubonic plague caused by rats infected by bacteria.
More than half of the population of Europe was killed due to his plague, which immediately creates a shortage of labor. Shortage of labor, including agricultural ones, immediately meant that the living ones would receive a higher wage, to the consternation of the landowners who pushes for legislation that would return the status quo to how it was prior to the Black Death. This enrages the peasants who worked for them; manifesting in several revolts from May to November 1380.

All of the above-mentioned events happen in chronological order for the hurricane-force winds to occur.
1. Tropical disturbance occurs from the tropics and the subtropics. These are generally 100-300 miles in diameter. It is a tropical weather system of organized conventions. This is the first stage that consists of a loosely organized low-pressure area.
2. Tropical depression is a more organized deep convention and has a closed circulation of sustained winds of less than 39 mph.
3. Tropical storm is the third stage that has sustained winds between 39 - 73 mph.
