Answer:

6.65 grams of Fe₂O₃ are required to produce 4.65g Fe.

Explanation:

The balanced reaction is:

Fe₂O₃ + 3 CO → 2 Fe + 3 CO₂

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

  • Fe₂O₃: 1 mole
  • CO: 3 moles
  • Fe: 2 moles
  • CO₂: 3 moles

The molar mass of each compound is:

  • Fe₂O₃: 159.7 g/mole
  • CO: 28 g/mol
  • Fe: 55.85 g/mole
  • CO₂: 44 g/mole

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

  • Fe₂O₃: 1 mole* 159.7 g/mole= 159.7 grams
  • CO: 3 moles* 28 g/mol= 84 grams
  • Fe: 2 moles* 55.85 g/mole= 111.7 grams
  • CO₂: 3 moles* 44 g/mole= 132 grams

Then you can apply the following rule of three: if by stoichiometry 111.7 grams of Fe are produced from 159.7 grams of Fe₂O₃, 4.65 grams of Fe are produced from how much mass of Fe₂O₃?

mass of Fe_{2} O_{3} =\frac{4.65 grams of Fe*159.7 grams  of Fe_{2} O_{3}}{111.7grams of Fe}

mass of Fe₂O₃= 6.65 grams

<u><em>6.65 grams of Fe₂O₃ are required to produce 4.65g Fe.</em></u>

Correct Answer is 1 i.e. Gamma rays—2 and radio waves—3

Reason: 
1) In a hypernova, star<span> as similar to </span>nuclear fusion<span> converts lighter elements into heavy elements. If fusion is not capable of generating enough pressure to counteract gravity, star immediately collapses to form a </span>black hole<span>. During this process, energy will be released, along the axis of rotation to form </span>gamma-ray burst. Such gamma-ray burst was first detected using <span>Fermi Gamma-ray Space Telescope. Thus, gamma-ray is capable of providing information of gravity fields.

2) Radiowaves are capable of inducing transitions that requires less energies. These transition includes nuclear excitation and electron excitation (in rotational energy level). Depending upon the value to Jmax, it is possible to determine the temperature and </span><span>heat released by astronomical objects</span><span>

Calculate the compound amount. Use the compound amount formula and a calculator. (Round your answer to two decimal places.) P =
Julli [10]

Answer:

The compound amount is $303.03 .

Explanation:

Formula for compound interest:

A=P\times (1+\frac{R}{n})^{tn})

Principle amount  = $1100

Rate of the interest compounded semiannually :

= R = 9% = 0.09

Number of times interest compounded, n = \frac{12}{6}=2

(semi means two times in a year)

Time period = T = 14

A=\$1100\times (1+\frac{0.09}{2})^{2\times 14}=\$303.0310\approx \$303.03

The compound amount is $303.03 .

Which actions are part of a system of methodical tests and refinements specific to technological design? 1 documenting, tinkerin
telo118 [61]

Answer:

1. documenting, tinkering, testing

Explanation:

Technological design is defined as the process of study, design and development of new technologies.

There are some action in the methodical tests and refinements specific to technological design include documenting, tinkering, testing.

<u>Documenting </u><u>includes collecting all the information about the design and develop the product, </u><u>tinkering</u><u> involves repairing or adjust the issues found in the development, and </u><u>testing </u><u>helps to evaluate if the product is ready to work as it is supposed to.</u>

Hence, the correct answer is "1."
