which of the following species has the same number of protons as fe³⁺?

Answers

Answer 1

The number of protons in an element is the atomic number of the element, and it is not affected by the charge on the element. Hence, the species which has similar Number of proton is Fe²⁺

To know the species which the same number of protons as Fe³⁺, we need to obtain the atomic number of the elements on the periodic table :

Fe³⁺, Atomic number = 26; Number of protons = 26

Mn³⁺, Atomic number = 25; Number of protons = 25

Co²⁺, Atomic number = 27; Number of protons = 27

Fe²⁺, Atomic number = 26; Number of protons = 26

Ni, Atomic number = 28; Number of protons = 28

Therefore, only Fe²⁺ has the same number of protons as Fe³⁺

What is a court?

Plessy v. Ferguson was a landmark 1896 Supreme Court decision that upheld the legality of racial segregation under the "separate but equal" principle. The case began in 1892, when African-American railroad traveler Homer Plessy refused to ride in a vehicle reserved for blacks.

The Supreme Court rejected Plessy's claim that his protected rights were violated, ruling that legislation that "implies only a juridical disparity" between whites and blacks was not unlawful. As a result, Jim Crow laws and segregated open lodging based on race became popular.

Therefore, the correct option is b.

One of the legs of a right triangle measures 2 cm and its hypotenuse measures 9 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.

Answers

Answer:

The measure of the other leg = 8.8 cm

Explanation:

Given - One of the legs of a right triangle measures 2 cm and its hypotenuse measures 9 cm.

To find - Find the measure of the other leg.

Proof -

We know that,

For a right angle triangle,

Apply The Pythagoras Theorem , which states that

(Hypotenuse)² = (Base)² + (Perpendicular)²

Given that,

Hypotenuse =  9 cm

One leg = 2 cm

Let us assume that,

One leg is base and another leg is Perpendicular.

We also can suppose vice-verse, it does not affect the solution.

Now,

(Hypotenuse)² = (Base)² + (Perpendicular)²

⇒(9)² = (2)² + (Perpendicular)²

⇒81 = 4 + (Perpendicular)²

⇒81 - 4 = (Perpendicular)²

⇒77 = (Perpendicular)²

⇒√77 = Perpendicular

⇒Perpendicular = 8.775 ≈ 8.8

∴ we get

The measure of the other leg = 8.8 cm

"I know not how it was – but, with the first glimpse of the building, a sense of insufferable gloom pervaded my spirit."

Answers

The question requires the indication of the sources of the narrator's perspective, which are as follows:

Passage 1 notes that the narrator expressed "a sense of insufferable gloom" to indicate that the narrator's perspective is obtained in the story.

The knowledge came to the narrator immediately after the building came into view. Observation is when the narrator gains perspective in the story.

Passage 2, where the narrator discusses his intimate friends, shows that the narrator obtains knowledge from the past.

Background information helps the narrator to know from the past.

The third passage shows that the narrator is making an inference. After observing the vault or tunnel, the narrator concludes that the design is conveying an idea.

An inference's basis is on some evidence. In addition, an inference can also be arrived at with reasoning based on observation and background information.

Thus, the narrator's inference is a conclusion arrived after observation or based on background information.

It removed the monetary limits that corporations and individuals can spend to independently influence an election.It increased the amount of money spent on elections. It resulted in a small number of wealthy individuals having undue influence in elections.

Citizens United v FEC was a 2010 case about the disagreement relating to the amount that can be spent on elections. The Supreme Court eventually ruled 5-4 and stated that the First Amendment gave rights to companies to spend on elections and that there was no limit on such amount.

Therefore, the monetary limits that corporations and individuals can spend to independently influence an election were removed. This ensured that there was an increase in the amount of money that was spent on elections.

Also, the decision by the Supreme Court resulted in a small number of wealthy individuals having undue influence in elections.

In conclusion, Citizens United changed campaign finance laws as the limits on the amount that can be spent on elections were removed.
