Starting with 100.0 grams of carbon and an excess of silicon dioxide and calcium phosphate, the number of moles of phosphorus produced can be calculated using the balanced chemical equation and the molar masses of the substances involved.
To determine the number of moles of phosphorus produced, we need to use the balanced chemical equation and the molar masses of the substances involved. The balanced equation provided shows the reaction between calcium phosphate (Ca3(PO4)2), silicon dioxide (SiO2), carbon (C), and phosphorus (P), along with the products calcium silicate (CaSiO3) and carbon monoxide (CO). However, it seems that the equation you provided is not balanced correctly. To accurately calculate the number of moles of phosphorus produced, a balanced equation is necessary.
Once the balanced equation is obtained, we can convert the given mass of carbon (100.0 grams) to moles using its molar mass. Then, using the stoichiometry of the balanced equation, we can determine the molar ratio between carbon and phosphorus to calculate the number of moles of phosphorus produced.
Without a properly balanced equation, it is not possible to provide an exact calculation of the moles of phosphorus produced.

Which Sung dynasty innovation most helped sea trade flourish?gunpowderthe compassthe Silk Roadthe Grand Canal
The innovation from the Sung dynasty that most helped sea trade flourish was the compass.
The compass was a crucial innovation that revolutionized maritime navigation during the Sung dynasty. It provided sailors with a reliable method for determining direction, allowing them to navigate accurately even when out of sight of land. By using the magnetic properties of the compass needle aligned with the Earth's magnetic field, sailors could maintain a steady course and explore new trade routes with greater confidence.
The invention of the compass significantly enhanced the safety and efficiency of sea travel. It enabled sailors to venture farther into unknown waters, discover new trade routes, and establish profitable connections with distant regions. The compass played a pivotal role in the expansion of maritime trade during the Sung dynasty, facilitating exchanges of goods, ideas, and cultures between China and other parts of Asia and beyond. Without the compass, sea trade would have been much more challenging, and the extent of global connectivity achieved during this period would have been significantly limited.

Answer:
Internet Access in China
Issue
Around the world, people use the internet to access information, entertainment, and more. We tend to think of the internet as a system that lacks control, and which everyone is able to access. However, this is not the case in China. China follows a strict mechanism of censorship that restricts the internet for Chinese people. This censorship and surveillance affects roughly 700 million users. Many of these have fought in different ways for free access.
Key people and organizations
It is not easy to establish who is fighting against the system, as these people are often hiding from authorities. However, this group often includes hackers, coders, software programmers, political activists, developers and virtual private network (VPN) suppliers.
Methods and strategies
One of the strategies these groups use is that of developing code or other tools to circumvent the government's censorship. Famous examples are Shadowsocks and GoAgent. VPN allows users to tunnel into the Internet via a different country. Therefore, these are popular among users as well.

Emerald bout 50 pineapples at 50coins each and sold the for $31. 0. Calculate the profit on the 50 pineapples
Emerald's profit on the 50 pineapples can be calculated by subtracting the total cost of purchasing the pineapples from the total revenue generated from their sale.
To calculate the profit on the 50 pineapples, we need to determine the total cost and the total revenue. Emerald bought 50 pineapples at a cost of 50 coins each, resulting in a total cost of 50 coins x 50 pineapples = 2500 coins.
Emerald then sold the pineapples for $31.00. Since the currency is not specified, let's assume it is in dollars. Therefore, the total revenue from the sale of the pineapples is $31.00.
To calculate the profit, we subtract the total cost from the total revenue: $31.00 - $2500 = -$2469.00.
The negative value indicates a loss rather than a profit. In this case, Emerald incurred a loss of $2469.00 on the 50 pineapples.
It's important to note that the profitability of the transaction depends on various factors such as the initial cost of the pineapples, additional expenses (e.g., transportation, packaging), and the selling price. Without more information, we can only calculate the profit/loss based on the given figures.

The profit on the 50 pineapples is $6.00.Emerald bout 50 pineapples at 50coins each and sold the for $31. 0.
To calculate the profit on the 50 pineapples, we need to determine the total cost of purchasing the pineapples and subtract it from the total revenue generated from selling them.
given:
number of pineapples bought: 50
cost of each pineapple: 50 coins
total revenue from selling: $31.00
step 1: calculate the total cost of purchasing the pineapples:
total cost = number of pineapples bought * cost of each pineapple
total cost = 50 * 50 coins
step 2: convert the cost to dollars:
total cost in dollars = (total cost in coins) / (exchange rate from coins to dollars)
note: the exchange rate is not provided in the given information, so we'll assume an exchange rate of 1 coin = $0.01 (1 cent).
total cost in dollars = (50 * 50 coins) * ($0.01/coin)
step 3: calculate the profit:
profit = total revenue - total cost in dollars
profit = $31.00 - total cost in dollars
let's calculate the total cost in dollars first:
total cost in dollars = (50 * 50 coins) * ($0.01/coin)
total cost in dollars = 2500 coins * $0.01/coin
total cost in dollars = $25.00

Choose a labor union and briefly describe who they were and what they did.
The labor union chosen for description is the American Federation of Labor (AFL). Founded in 1886, the AFL was a federation of skilled craft unions that advocated for workers' rights, higher wages, and improved working conditions through collective bargaining and strikes.
The American Federation of Labor (AFL) was a significant labor union in the United States during the late 19th and early 20th centuries. It was founded in 1886 by Samuel Gompers and served as a federation of various skilled craft unions. The AFL primarily represented the interests of skilled workers, such as carpenters, plumbers, and electricians.
The AFL focused on achieving better working conditions, higher wages, and improved benefits for its members. It believed in the power of collective bargaining, where the union negotiated with employers on behalf of its members to secure favorable terms of employment. The AFL emphasized the idea of "bread and butter" unionism, focusing on immediate and practical gains for workers rather than broader political or social reforms.
The AFL played a significant role in the labor movement, advocating for the eight-hour workday, workplace safety regulations, and the end of child labor. It also organized strikes and boycotts to put pressure on employers to meet the demands of workers. The AFL's approach of organizing skilled workers and negotiating with employers influenced the development of modern labor practices and set the foundation for later labor unions in the United States.

TRUE/FALSE. between 2005 and 2007, asphalt firms in kentucky practiced tacit collusion.
It is True that between 2005 and 2007, asphalt firms in kentucky practiced tacit collusion.
Tacit collusion refers to a situation where competing firms engage in a coordinated behavior that leads to higher prices and reduced competition, without any explicit agreement or communication.
Instead, the firms may use implicit signals or understandings to coordinate their actions, such as following the lead of a dominant firm or matching each other's prices.
Tacit collusion occurs when firms in a market engage in coordinated behavior without any explicit agreement or communication. They might do this by following the actions of a dominant firm or by making strategic decisions based on their understanding of the market.
In the case of asphalt firms in Kentucky between 2005 and 2007, there was evidence of tacit collusion. According to a study by the Kentucky Legislative Research Commission, during this period, asphalt prices increased significantly, and there was a high level of concentration in the market.
The study found that the price increases were not entirely due to the rising costs of raw materials, such as oil. Instead, it was suggested that the high market concentration allowed firms to coordinate their pricing decisions and effectively raise prices without any explicit agreement or communication.
This behavior is consistent with the concept of tacit collusion, where firms in a concentrated market engage in coordinated pricing strategies without explicit communication or agreements.
In the case of the Kentucky asphalt market, the evidence suggests that this type of collusion was practiced between 2005 and 2007.
In conclusion, it is accurate to say that between 2005 and 2007, asphalt firms in Kentucky practiced tacit collusion, leading to increased prices and market concentration during that time period.
