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.

Answer: Expert testimony and Metaphor

Explanation: Expert testimony is correct, its just the repetition is not.

Repetition is like when it is repeated:

Example: King repeats “We cannot” followed by “we are not” and “we will not” to build emotion and reveal his steadfast commitment to the cause.

Thats why the other person got it wrong, but if u put Expert testimony and Metaphor, you would get it right.

Which narrative point of view is used in this excerpt from Alice’s Adventures in Wonderland by Lewis Carroll?

And so it was indeed: she was now only ten inches high, and her face brightened up at the thought that she was now the right size for going through the little door into that lovely garden. First, however, she waited for a few minutes to see if she was going to shrink any further: she felt a little nervous about this; 'for it might end, you know,' said Alice to herself, 'in my going out altogether, like a candle. I wonder what I should be like then?' And she tried to fancy what the flame of a candle is like after the candle is blown out, for she could not remember ever having seen such a thing.

After a while, finding that nothing more happened, she decided on going into the garden at once; but, alas for poor Alice! when she got to the door, she found she had forgotten the little golden key, and when she went back to the table for it, she found she could not possibly reach it: she could see it quite plainly through the glass, and she tried her best to climb up one of the legs of the table, but it was too slippery; and when she had tired herself out with trying, the poor little thing sat down and cried.

Christopher Columbus was a famous explorer who discovered the New World while searching for a western route to the Indies. Although all other merchants had traveled eastward to the Indies, Columbus was convinced he could reach the Indies by traveling west.

Although Christopher Columbus did not find what he was looking for, on October 12, 1492, he and his men discovered the New World. The world owes a great debt to the courageous explorations of Christopher Columbus.

A connotation is a generally accepted social or psychological association that every particular word or phrase possesses. A connotation is typically regarded as either good or negative in terms of the emotional connection it evokes. The contrast of connotation is denotation.

The negative connotation uses the term loathed, which refers to detest intensely and frequently with contempt or hatred. "The reef sat beneath the surface" uses the neutral connotation. The positive connotation uses the term glimmered, which refers to shine with a fading light or a brightness that doesn't last.

Desdemona tells her father that although she loves him, her duty is now to Othello. At what point does a person's obligation move from their parents to their significant other? Is it possible to be obligated to parents and a significant other? If yes, what potential problems may arise? If no, what potential problems may arise?

Answers

Answer and Explanation:

1. The point of obligation of a person passes from the country to another individual when there is greater responsibility than that other individual requires. As shown in the question above, Desdemona had a strong obligation to care for and support her husband, as she lived in a time when women were "properties" of their husbands and were to devote themselves completely to them.

2. It is possible to have an obligation to parents and to another individual, as long as the person who has this obligation is able to organize well and get help, because having obligations to someone is a very big burden and the more people who have this obligation, the greater the burden.

3. The problems that can be generated from this is the overload of people who have obligations to many other people. In this case, to avoid these problems it is necessary to define priorities and delegate the obligations to those involved.
