Where did the name spitfire come from?

Oh honey, the name "spitfire" originated during World War II to describe a type of British fighter aircraft known for its speed and agility. The term was used to highlight the aircraft's fiery temperament and aggressive nature in combat. So, next time you hear "spitfire," just remember it's not just a sassy nickname for your feisty grandma, it's a nod to some badass planes from history.

Why was an Anderson shelter called an Anderson shelter?

An Anderson shelter was called an Anderson shelter because the person that invented them, his second name was Anderson. Same with a Morrison shelter really.

Why was the underground used during the blitz?

During the Blitz, the underground stations in London were used as shelters to protect civilians from the relentless bombing raids by the German Luftwaffe. The deep, sturdy platforms provided a safe refuge from falling debris and explosions, accommodating thousands of people seeking safety from the attacks. Additionally, the underground offered basic amenities, such as benches and sanitation facilities, making it a viable option for those forced to spend long hours away from their homes. This use of the underground not only saved lives but also fostered a sense of community among those who shared the experience.

Why did canals have towpaths?

When first constructed, barges had no motor to propel them , Hence to move along a canal horses were used.

The barge in the canal ; the horse on the tow path ; a rope was attached between the barge and the horse, and the horse moved forward. Because the barge was in a 'soft' medium' ; water, the horse did not have to put in too much effort to move the barge.

There would be a bargemen to steer the barge , and an hostler to guide the horse.

In this modern era, barges, whilst looking like old time barges, do have a motor, so the use of an horse is no longer required.

The channel of water between united kingdom and France?

The English call this the 'English Channel', the French call it 'la Manche' (the sleeve).

The rest of the British people call it the 'English Channel' as well.

Who was prime minister of Germany after World War 2?

Theodor Huess was elected Federal President of West Germany on September 12, 1949, and Konrad Adenauer was elected Federal Chancellor of West Germany three days later on September 15. I am not knowledgeable enough to say which office was the closest counterpart to that of a prime minister, but I remember that Adenauer's name comes up most frequently on the subject of postwar Germany.

What is the molecular formula of a compound given the molar mass of the compound is 186.5g and the empirical formula is C2H7?

The molecular mass is C2H7

you have 186.5 g of the substance, so calculate

2(12.01)+7(1.01)=31.09

so 186.5/31.09=6

so you can say C12H42

but when you divide 2 by 2 and 7 by 2 you obtain 1 and 3.5 because you have 3.5 you have to multiplied by 2 again, so you obtain the same formula as the empirical formula.

It example is the same as water, which empirical formula es H2O as its molecular formula

How many degrees are between Winston-Salem time zone and New Orleans Time Zone?

There is no time difference between Winston-Salem and New Orleans as they are both in the Eastern Time Zone.

Who rings in the new year at 7pm central time?

At 7pm central time, countries in the UTC+3 timezone like Kenya, Iraq, and Saudi Arabia often celebrate the new year. These regions are ahead of central time zones, so they ring in the new year earlier.

What Hydroquinone is an organic compound It has a molar mass of 110.1 grams over mol and a composition of 65.45 percent C 5.45 percent H and 29.09 percent O by mass. What is the molecular formula?

Firstly divide percentages by molar mass of that element

C

65.45/12.01=5.45

H

5.45/1.01=5.40

O

29.09/16=1.82

Then divide the result of the first step by the smallest answer

C

5.45/1.82=3

H

5.40/1.82=3

O

1.82/1.82=1

Empirical Formula is C3H3O

If the molar mass is 110.1 we can divide this by our empirical formulas molar mass to get the molecular formula.

so 110.1/(12.01x3+1.01x3+16)=110.1/55.06=2

so the molecular formula is C6H6O2

What was faster spitfire or the hurricane?

The Supermarine Spitfire was faster than the Hawker Hurricane, with a top speed of over 360 mph compared to the Hurricane's top speed of around 340 mph. The Spitfire also had better overall performance characteristics, making it a more capable fighter aircraft.

Why is the bulb evacuated?

If they were not evacuated of all outside air, the filament will burn up in seconds because the air Will cause Resistance, thus the filament will burn brighter and brigther tyring to burn off the air until it opens. (blown bulb)...

How and when was universal begin?

About a half a million years after the big bang, the cosmos began to cool, as it cooled, the hot subatomic particles that constituted the early universe began to slow down and stop colliding with each other long enough so that protons, neutrons and electrons could form. The universe cooled further and the hot particles slowed further still allowing these particles to stay together long enough to create atoms.The universe was nothing but a cloud of hydrogen and helium. Slowly, the universe continued to cool and structure begins to present itself within this universal cloud.

What is the physical difference between spitfire and the hurricane aircraft?

Both were formidable RAF fighters in WW II. The Hurry was built largely of wood with a fabric covering, while the Spit was built from metal with a high-strength aluminum covering. The Spit, or at least the later ones, had a higher-visibility canopy.

Would world maps made in different countries have different perspectives?

Yes, world maps made in different countries may have different perspectives due to the varying emphasis placed on certain regions or characteristics. Additionally, cultural biases or historical influences can impact how countries choose to portray the world. Overall, maps can be subjective and may reflect the priorities or viewpoints of the cartographer or society in which they were created.

Calculate the molecular formulas of the compounds having the following emprical formulas and molar masses C2H5 58g mol?

To determine the molecular formula, we first need to calculate the empirical formula mass of C2H5. The empirical formula mass can be calculated by adding the molar masses of each element in the empirical formula: 2(12.01) + 5(1.01) = 29.07 g/mol. Next, divide the molar mass of the compound (58 g/mol) by the empirical formula mass (29.07 g/mol) to find the multiplier: 58 g/mol / 29.07 g/mol = 2. This multiplier gives the molecular formula of the compound, so the molecular formula is (C2H5)2 or C4H10.

Explain why the percent composition of certain compounds are not sufficient to determine the compounds molecular formulas?

Because unlike the empirical formula, the molecular formula does not have to be the simplest ratio.

If by chance you are given the percent composition of the elements in a substance, you could calculate the empirical formula and then the empirical formula's mass. However, the molecular formula equation is molecular formula= (empirical formula)n, where n is the mass of the molecular formula divided by the mass of the empirical formula. You would, therefore, need to know the mass belonging to the molecular formula, which you are not given.

If Anna Anderson was cremated how could they test her DNA later?

Not from her ashes, but it is possible to chemically examine clothes worn by Anna Anderson and the real Czarevna- if any survive- under special microscopic light- and body stains, etc could conceivably be tested- as has been done with even inanimate object such as the Shroud of Turn, dating to Biblilcal times. Leave Her residuum alone!If you want to analyze fabrics of her clothes, okay.

The first woman to win the nobel prize in literature in 1993?

Toni Morrison was the first African American woman to win the Nobel Prize in Literature in 1993. Her works, including "Beloved" and "Song of Solomon," are celebrated for their poetic language and exploration of African American culture and history. Morrison's win marked a significant moment in recognizing the literary contributions of women and minority writers.

Is ammonia gas is dangerous to human being?

Ammonia is highly toxic to human beings. Though the scientists are not able to identify the cause of the toxicity but they have certain speculations. The ammonia toxicity finally leads to a state called as comatose state that is accompanied by cerebral edema (increase in the water content of cerebrum.

What were spitfires and hurricanes?
