gives the people more power and influence in the government

#3 Which statement BEST expresses the theme of this short story? Narrow your choices and think carefully!

Question 4 options:

Attempting to achieve complete equality will only result in widespread dissatisfaction and lack of creativity.

The government should encourage everyone to hide their differences in order to have a more peaceful and equal society.

Forcing uniformity on people doesn't result in equality, but rather causes conflict and unhappiness.

People don't realize how important individuality is until they have what makes them different taken away.

PART A: How do the different handicaps contribute to the theme of the story?

Question 5 options:

They show how being unique can be dangerous to yourself and the people around you.

They emphasize how the most ordinary people are often the most valued in a society.

They stress how the work towards achieving total equality won't be easy or pleasant.

They illustrate how much must be done to make the most unique and talented individuals conform.

“he tried. That's the big thing. He tried to do the best he could with what God gave him. He should get a nice raise for trying so hard.” (Paragraph 39)

“And it was easy to see that she was the strongest and most graceful of all the dancers, for her handicap bags were as big as those worn by two-hundred pound men.” (Paragraph 40)

“Diana Moon Glampers loaded the gun again. She aimed it at the musicians and told them they had ten seconds to get their handicaps back on.” (Paragraph 79)

Which statement best expresses the central idea in the article "Proposed Treatment to Fix Genetic Diseases Raises Ethical Issues"?

Question 7 options:

Scientists have discovered a way to prevent genetic defects in babies, but some believe genetic development should be left to nature

Scientists have discovered a way to prevent genetic defects in babies, but some worry that the process could be used for great economic gain

Scientists have discovered a way to prevent genetic defects in babies, but the method is against many families’ religions

Scientists have discovered a way to prevent genetic defects in babies, but the process is still very risky

The primary purpose of the article is to...

Question 8 options:

inform

entertain

narrate

persuade

PART A: In paragraph 3 and paragraph 24, what is meant by the phrase “designer babies”?

Question 9 options:

Babies that are bred to be particularly attractive

Babies whose DNA has been altered to enhance a specific positive trait

Babies whose DNA has been altered to avoid disease

The biological children of genetic researchers

PART B: What detail from the text best supports the answer for Part A?

Question 10 options:

“…the research would create an egg with healthy mitochondrial DNA (mtDNA).” (Paragraph 4)

“First of all, the baby would be born with genes from three different people… (Paragraph 18)

“…we're going to allow inheritable genetic changes to make healthier children…” (Paragraph 25)

“…we’re going to allow these kinds of genetic engineering experiments to make children who are more intelligent or more athletic or have perfect pitch…” (Paragraph 25)

The primary purpose of Gavin DeGraw's song "I Don't Want To Be" is to...

Magnesium reacts with hydrochloric acid to produce magnesium chloride and hydrogen gas. Write a balanced chemical equation for t
Alona [7]

Answer:

The balanced chemical equation is Mg + 2HCl ⇒ MgCl2 + H2

The molarity of the hydrochloric acid solution is HCl 0.04 M and the pH = 1.4.

The volume of hydrogen gas produced by the reaction of 0.510 g of Mg will be 0.482 L.

Explanation:

First, for the balanced equation you have to consider the oxidation state of the elements to find subscripts. Then you can find the correct coeficients. Mg= +2, Cl = -1.

Mg + HCL ⇒ MgCl2 + H2

For the molarity of the solution you have to notice tha if 0.510 grams of Mg reacts with 0,5 L of hydroclhoric acid, and from the previous equation 1 mol of Mg reacts with 2 mol HCl.

The atomic mass of Mg = 24.31 grs/mol

24.31 grs------------ 1 mol Mg

0.510 grs------------ x=0.02 mol Mg.

If 1 mol of Mg reacts with 2 mol HCl, then 0.02 mol of Mg will react with

0.04 mol HCl. So, the molarity of the solution is 0.04 M HCl.

Then to calculate the pH we use the formula pH = - log [H+]

⇒ pH = -log [0.04]⇒ pH=1.4.

Finally, from the balanced equation and the findings described, and considering that at 25°C and 1.00 atm 1 mol of gas has volume of 24.1 L.

1 mol H2----------- 24.1 L

0.02 mol H2----- x= 0.482L.

Forces and Motion:Question 1
defon

Answer:

Velocity = 12 km/h

Explanation:

Velocity can be defined as the division between distance traveled and the time it took for that distance to be traveled:

  • Velocity = Distance / Time

With the above information in mind, we can calculate the velocity of the bicycle:

  • Velocity = 18 km / 1.5 h
  • Velocity = 12 km/h

Thus the velocity of the bicycle is 12 kilometers per hour.

When ammonium chloride crystals are dissolved in water, the temperature of the water decreases. What does the temperature change
sertanlavr [38]

Answer:

See Explanation

Explanation:

A decreasing temperature indicates that the dissolution process for the ammonium chloride requires input of energy from surroundings. That is, the process is essentially 2 parts => system (object of interest - NH₄Cl) and the surroundings (everything else - solvent - H₂O). The surroundings (water) solvent is showing a <u>measured</u> decrease in temperature or loss of energy (exothermic to surroundings) which flows into the system (NH₄Cl) and effects dissolution of salt into solution (endothermic to system).

Write the empirical formula for at least four ionic compounds that could be formed from the following ions:
love history [14]

Answer:

FeSO_{4},FeCH_{3}CO,Fe_{2}(SO_{4})_{3},Fe_{2}(CH_{3}CO)_{3}

Explanation:

Empirical formula of ionic compound formed by two ions A^{x+} and B^{y-} is A_{y}B_{x} (for x\neq y) of AB (for x = y)

The above empirical formula is in accordance with charge neutrality principle

Here each cation (Fe^{3+} and Fe^{2+}) can form two ionic compounds by combining with two given anions (SO_{4}^{2-} and CH_{3}CO^{2-}).

So the four ionic compounds are: FeSO_{4},FeCH_{3}CO,Fe_{2}(SO_{4})_{3},Fe_{2}(CH_{3}CO)_{3}
