Water is produced from the reaction of hydrogen and oxygen gas, according to the equation below. What is the excess reactant in the reaction of 4.2 moles of hydrogen with 3.0 moles of oxygen?

2H2(g) + O2(g) = 2H2O(L)

Select one:
a. Water
b. Oxygen
c. No excess reactant
d. Hydrogen

Answers

Answer 1

Answer:

b. Oxygen

Explanation:

It can be seen that the chemical equation have 2 moles of hydrogen gas that should be reacted with the one mole of oxygen gas

Now for 4.2 moles, the hydrogen gas would be reacted as

= 4.2 × 1 ÷  2

= 2.1 mole oxygen gas

Therefore the hydrogen would be limited the reagent because it limits the product formation

On the other hand, the oxygen is the excess reagent i.e.

= 3 - 2.1

= 0.9 moles

This would be left for oxygen

Hence, the correct option is b.

What do we gain from watching media that do not present a universal truth?

D. All of the above​

Answer:

(D) I think

Now lets Look at Answer B; An expanded knowledge of the world around us. When we see something non-realistic we know we can expand our knowledge of how it could be and would be.

Next let's look at Answer C; Something completely removed from our own lives. If something isn't real it was probably a possibility we were thinking of it in our own life's. But if we watched a movie or television show we would have that knowledge removed from our everyday life's

In which sentence does the verb agree with the subject?

A. The tone and pitch of the sparrow's song is pure and clear.
B. Hermit thrushes and wood thrushes is a delight to hear.
C. The lark and the robin are loved for their music.
D. Sunflower seeds or corn attract a variety of birds.

Answers

Answer:

The sentence in which the verb agrees with the subject is:

C. The lark and the robin are loved for their music.

Explanation:

With just a couple of rules, we are able to answer this question easily. First, when we have a compound subject joined by "and", the verb should be plural, since it refers to both elements in the subject. That is why letters A and B are wrong. Letter C, however, does present a verb with a plural conjugation, which makes it correct.

When a compound subject is joined by "or", and one of the elements is plural, the verb will agree with the element that is nearer. Letter D is incorrect because "attract" should agree with "corn" and not "seeds".

The Dawn’s Awake
By Otto Leland Bohanan

The Dawn’s awake!
A flash of smoldering flame and fire
Ignites the East. Then, higher, higher,
O’er all the sky so gray, forlorn1,
The torch of gold is borne.

The Dawn’s awake!
The dawn of a thousand dreams and thrills.
And music singing in the hills
A paean2 of eternal spring.
Voices the new awakening.

The Dawn’s awake!
Whispers of pent-up harmonies,
With the mingled fragrance of the trees;
Faint snatches of half-forgotten song--
Fathers! Torn and numb,--
The boon of light we craved, awaited long,
Has come, has come!

1Pitifully sad and abandoned or lonely
2A song of praise or triumph

Directions: Identify the type of figurative language that best fits the bolded words or phrases. Then explain how each one helps develop imagery within the poem. Remember that your responses should be at least 3-5 sentences in length.

The Black Land
By Joseph Warren Beach

I will pough the land,
Turning up the black soil.
I will ride upon this heaving surface
As a boat rides upon the water.
Even as a boat
Cleaving the water with an eager keel,
I have run a furrow1
Straight across the ridges.

I will sow down this field,
Scattering gems.
With both hands will I scatter
Quivering emeralds out of a bottomless pouch.

As I tread the loam2
My feet sink deep.
The black earth embraces my ankles
And clings to my bent knees.

I sing as I go
Scattering emeralds.
The wind sings upon my lips,
And pearls stream off my neck and forehead.
I am bathed in a sweat of pearls.

Eyes straight forward
Rest on a brightening ultimate slope.

1A long narrow trench made in the ground by a plow.
2Soil with equal amounts of sand, silt, and clay.

Directions: Identify the type of figurative language that best fits the bolded words or phrases. Then explain how each one helps develop imagery within the poem. Remember that your responses should be at least 5-7 sentences in length.

I had to wait four more hours and I was sleepy so I decided to take a nap and set an alarm to wake up in time for my flight. But I didn't. I missed it and I got stranded in the airport for one whole day. It was the first thing that went wrong but not the only one. When I finally arrived to Australia, I had a lot of bad experiences. I felt lonely, I lost money and I missed home. However, I also made friends for life, I discovered amazing landscapes and I had the time of my life. So, nevertheless, it was my best experience.

Arranging things in a sequence, where each things precedes or succedes another is called ordering. Ordering can be done in several ways, depending on ordering criteria.

For example, we can arrange events chronologically, which means we arrange them based on the time period when they occured; from the most to the least recent event, or vice versa.

Spatial arrangement means that we list things based on their position in space; from right to left, or from top to bottom.

Logical order is when we place things in a manner that each one logically follows the previous.

However, in this example, we have climatic order, which means that things are arranged in an order from the least important to the most important, making the final thing on the list the most important, or strongest, or the best.

Breakup Paragraphs

Answer:

Well first off, start at the beginning. Make sure you include sufficient background information, a good hook, and a good thesis. Background info are usually 2-4 sentences. The hook and thesis should be 1 sentence. (2 is max and pushing it).

For the body paragraphs:

Thesis statements at the beginning should be 1 sentence long.

The evidence should be good to well support what you are explaining, informing, entertaining, or arguing about. In a body paragraph, there is usually 1 to 2 evidences. 2 is better because it supports your reasons more. Along with these evidences comes the elaboration. These elaborations seem to want to be 1 sentence long, but don't let it make you. You should write maybe 2-4 sentences of elaboration, with 4 kind of pushing it. Make sure these sentences aren't run-on sentences as it can mislead information and take the reader away from the main topic. Transitions/restating the reason should take 1-2 sentences (2 pushing it a little).

If you are doing a argumentative essay, you will also include the counterclaim/argument. This will be 1-3 sentences long, where you describe the other side, give A reason why their side is somewhat better, than come back with saying why your reason is superior to the counter argument.

Finally, you have the conclusion. This will be restating your claim/thesis, adding a little background/forward thinking into it as well. Try leaving the reader with something to think about. The conclusions should usually be around 4 or 5 sentences.

Explanation:

Read the excerpt from “Flight into Yesterday.”

The plane reached the end of the runway, and Amelia swung it around. Home was 7,000 miles away, on the far side of the Pacific Ocean, and she yearned to be there. But one thing at a time. At this moment her job was to get the plane safely off the ground. The runway stretching ahead was a strip carved out of the jungle. About 3,000 feet long, it ended at a cliff that dropped away into the ocean.

Amelia pushed both throttles forward. The plane moved slowly heavy with fuel for the long ocean flight that lay ahead. At last it began to gather speed. It went fast and faster, hurtling toward the cliff. Almost at the very edge she felt it leave the ground. They were safely off, flying low over the ocean, but flying. Now she could concentrate on gaining altitude. She could start picking out the islands that would serve as landmarks for the early part of the flight.

Now, read a list that shows a sequence of events based on the excerpt.

A. Earhart tried to identify places that could help guide her.
B. The plane moved slowly because it was loaded with fuel.
C. The plane moved quickly as it headed toward the cliff.
D. Earhart turned the plane around on the runway.
