1. 4. Suppose a particular consumer has 8 birr to be spent on two goods, A and B. The unit price of good A is 2 birr and the unit price of B is 1 birr. The marginal utility (MU) she gets from
   
   consumption of the goods is given below.

   A) Based on the cardinal analysis, what is the combination of the two goods that gives maximum utility to the consumer?
   
   B) What is the total utility at the utility maximization level?

The following chemical reaction takes place in aqueous solution:

2AgNO3(aq)+Na2CO3(aq)→Ag2CO3(s)+2NaNO3(aq)

Blast furnaces extra pure iron from the iron(III) oxide in iron ore in a two step sequence. In the first step, carbon and oxygen react to form carbon monoxide:

2C(s)+O2(g)--->2CO(g)

In the second step, iron(III) oxide and carbon monoxide react to form iron and carbon dioxide:

Fe2O3(s)+3CO(g)--->2Fe(s)+3CO2(g)

Suppose the yield of the first step is 65.% and the yield of the second step is 94.%. Calculate the mass of oxygen required to make 6.0kg of iron.

Be sure your answer has a unit symbol, if needed, and is rounded to 2 significant digits.

The concepts of these three principles of cultural identity do not always mean hatred or bias, but can be used to help facilitate such feelings.

1 Can you give an example of ethnocentrism, patriotism and nationalism that you see in the United States?

2 Explain how each of these examples impacts the general international perspective of being an American citizen.

3 How might other nations view each of these examples? Do you think these examples shed a positive or negative light upon American culture?

900.0 mL of 3.00M phosphoric acid, H PO, reacts with 235 grams of iron (III) carbonate.

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?

For each reaction in the table below, write the chemical formulae of any reactants that will be oxidized in the second column of the table. Write the chemical formulae of any reactants that will be reduced in the third column.

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.
