In a certain chemical reaction Compound A combines with Compound B to produce Compound C (and no other products). Measurements were taken of the amounts of A and B present before and after a reaction that produced some C:

1) Calculate the theoretical yield of C. Round your answer to the nearest 0.1g.

2) Suppose the percent yield of C in this reaction was 48.%. Calculate the actual amount of C that was isolated at the end of the reaction. Round your answer to the nearest0.1g.

Gaseous methane (CH4) reacts with gaseous oxygen gas (O2) to produce gaseous carbon dioxide (CO2) and gaseous water (H2O). What is the theoretical yield of water formed from the reaction of 0.96g of methane and 3.3g of oxygen gas?

Part A:

The area of the rectangular field is:

(2.7 x 10^3 ft) x (3.5 x 10^3 ft) = 9.45 x 10^6 ft^2

Half of the field is used to grow crops, so the area of the portion with crops growing is:

(1/2) x 9.45 x 10^6 ft^2 = 4.725 x 10^6 ft^2

Part B:

To write the final answer in scientific notation with the correct number of significant digits and units, we need to round the result to two significant digits and include the units:

4.725 x 10^6 ft^2 ≈ 4.7 x 10^6 ft^2

Part C:

The original measurements in the problem were given to two significant digits, so the final answer should also have two significant digits. We rounded up from 4.725 to 4.7 because the next digit (5) is greater than 5, which means we round up according to rounding rules. Finally, the units of the answer are square feet, which come from multiplying the length and width of the rectangle.

Black Forest Biologicals, a biotech startup, has a promising Alzheimer's drug candidate Compound SLT-88 entering Phase I trials this year. SLT-88 is the only product formed by the reaction of two precursor compounds A and B, both of which are quite expensive. The chief medicinal chemist of Black Forest is trying out different reaction conditions to minimize the cost of manufacturing SLT-88.

In the table below are listed the initial and final amounts of A and B used under two different trial conditions, and also the actual amount of SLT-88 recovered in each case. Complete the table by calculating the theoretical yield of SLT-88 and the percent yield of SLT-88. Round your amounts to the nearest milligram and your percentages to the nearest whole percent.

Dinitrogen pentoxide gas (N2O5) is obtained by the reaction of nitrogen trioxide gas (NO3) and nitrogen dioxide gas (NO2).

Write a balanced chemical equation for this reaction.

Gaseous ethane (CH3CH3) reacts with gaseous oxygen gas (O2) to produce gaseous carbon dioxide (CO2) and gaseous water (H2O). What is the theoretical yield of carbon dioxide formed from the reaction of 29.5g of ethane and 71.3g of oxygen gas? 

Round your answer to 3 significant figures.

What are the consequences churning out substandard or defective products into the market. How does this align with Philip Crosby's philosophy of doing the job right the first time.

A common way to make hydrogen gas in the laboratory is to place a metal such as zinc in
hydrochloric acid. The hydrochloric acid reacts with the metal to produce hydrogen gas, which is then collected over water. Suppose a student carries out this reaction and collects a total of 154.4 mL of gas at a pressure of 742 mmHg and a temperature of 25 oC. What mass of hydrogen gas (in mg) does the student collect?

Paraphrase this equation

Part A: The expression that represents the amount of money the store made is (24)(35) + (15)(15) - 120.

Part B: To calculate the amount of money the store made, we need to find the total revenue from selling the keyboards and phone chargers and then subtract the cost of purchasing them. The revenue from selling 24 keyboards at $35 each is (24)(35) = $840, and the revenue from selling 15 phone chargers at $15 each is (15)(15) = $225. So the total revenue is $840 + $225 = $1065. Since the store bought the items for $120, we subtract that from the revenue to get the profit: $1065 - $120 = $945.

Part C: (24)(35) + (15)(15) - 120 = 840 + 225 - 120 = $945. Therefore, the value of the expression is $945, which represents the profit the store made from selling the keyboards and phone chargers.

The Digital Divide

By: Kim Czaccei Dacanay

The digital divide exists in the Philippine education system for the longest time, but the Pandemic exposed just how bad it is. The digital divide is the barrier between those who have access to computers and the internet and those who don't.   Educational attainment is heavily affected by the digital divide, and this remains true to many countries in the world. Many provinces in the Philippines have a slim to none access to the internet connection. Students and teachers would have to climb high places to get internet access. Also, as reported by STAR last year, 13 million Filipino households don't have electricity.   Therefore, the transition to online classes will put certain Filipino student population at a stark disadvantage. If there's no internet
