help pls
I will mark the brainless​

Answers

Answer 1

Answer:

281 g

Explanation:

The molar mass of a substance is the mass in grams of one mole of a substance. The molar mass is the ratio of  mass of a sample to the amount of substance in that sample. The molar mass is given by the formula:

Molar mass = mass / amount in mole

The molar mass of silicon = 28.0855 g/mol. Given that amount in mol = 10 mol, hence:

Molar mass = mass / amount in mole

28.0855 = mass / 10

mass = 280.855 g

mass ≈ 281 g

Read this excerpt from the introduction to Wheels of Change by Sue Macy.


When I was a kid, I took great pleasure in jumping on my bike and riding to the corner candy store about half a mile away. Although I had no knowledge of the part the bicycle had played as a vehicle of change for turn-of-the-20th-century women, I was acutely aware that it allowed this 1960s girl a unique measure of independence. On my bike, I could break free of the bonds that held me in my neighborhood to go buy Necco Wafers and candy necklaces and Atomic FireBalls. If I felt particularly adventurous, I could even ride a bit farther for a fresh ice-cream cone at Applegate Farm.


The author’s purpose for including this in the introduction is


to describe the research she conducted for Wheels of Change.

to explain the historical significance of bicycles.

to establish her credentials as an expert on bicycles.

to emphasize her personal appreciation for bicycles

Answers

Sterne purpose for writing was '' to show that he is sympathetic to Sancho’s cause''

Option C  is correct

The reason for Sancho's writing is to persuade Sterne to write more messages against slavery. This is shown in the passage from Letters of the Late Ignatius Sancho, an African who wants  to enlighten the open regarding the torment and abuse in  the subjection.

Why is Ignatius Sancho important?

Ignatius Sancho is commonly known for his letters about slavery. He sent missives to leading novelists explaining  himself as a black person and a former slave. He then requested the novelists to use the writings to highlight the  slavery in the British West Indies.

What is a Text Purpose?

This refers to the rationale for writing that an author undertakes when he wants to convey a thing to his readers.

Hence, we will see that from the complete text, there's the use of narration to show the reason why Sterne was writing and this is to show that he supports Sancho and is sympathetic to his cause.

The support by Sterne was to encourage Sterne to write down more about slavery which would help to show the evils of slavery and end it and also enlighten others.

Explanation:

Read the sample student claim and the reasons listed for making this claim.

Claim: Although many people argue that medical testing on animals is a violation of animal rights, the benefits it yields for society far outweigh any argument that can be made.

Reason #1: Animal research has yielded both pain-relieving and life-saving drugs for humans.

Reason #2: Laws prohibit scientists from using animal-based research in cases where non-animal testing would produce equally clear and valid results.

Which piece of evidence would best support reason #1?

The history of using animals for research extends as far back as 322 BCE, when early Greek physician-scientists, such as Aristotle and Erasistratus, performed various experiments on living animals.
Animal research played an essential role in the development of Herceptin and Tamoxifen, two medications that have already saved the lives of thousands of women who have been diagnosed with breast cancer.
Even those who believe in testing on animals when it is necessary for vital medical research practice what is known as “the 3 Rs”—reduction, refinement, and replacement—to reduce the number of animals used for testing.
Biologists believe that chimpanzees share at least 98.4 percent of the same DNA as humans and gorillas share at least 97 percent, making primates a popular and likely choice for the testing of products intended for humans.
