Answer:

William Shakespeare (bapt. 26 April 1564 – 23 April 1616)[a] was an English playwright, poet, and actor, widely regarded as the greatest writer in the English language and the world's greatest dramatist.[2][3][4] He is often called England's national poet and the "Bard of Avon" (or simply "the Bard").[5][b] His extant works, including collaborations, consist of some 39 plays,[c] 154 sonnets, two long narrative poems, and a few other verses, some of uncertain authorship. His plays have been translated into every major living language and are performed more often than those of any other playwright.[7] They also continue to be studied and reinterpreted.

Shakespeare was born and raised in Stratford-upon-Avon, Warwickshire. At the age of 18, he married Anne Hathaway, with whom he had three children: Susanna and twins Hamnet and Judith. Sometime between 1585 and 1592, he began a successful career in London as an actor, writer, and part-owner of a playing company called the Lord Chamberlain's Men, later known as the

What is the mass in grams of 4.85 x 1022 al atoms?
aliya0001 [1]

Based on the calculations, the mass of Aluminum in 4.85 × 10²² atoms is equal to 2.1762 grams.

<h3>How to calculate the mass of Aluminum?</h3>

In order to determine the mass of Aluminum, we would calculate the number of atoms in 1 mole of an Aluminum atom in accordance with Avogadro's constant.

1 mole of Aluminum atom = 6.02 × 10²³ molecules

X moles of Aluminum atom = 4.85 × 10²² molecules

Cross-multiplying, we have:

X = 4.85 × 10²²/6.02 × 10²³

X = 0.0806 moles.

Mass = Molar mass × Number of moles

Mass = 27 × 0.0806

Mass = 2.1762 grams.

** worth 20 points + brainliest **
Bad White [126]

Answer : The correct option is, (D) 83^oC

Solution :

Formula used :

Q=m\times c\times \Delta T=m\times c\times (T_{final}-T_{initial})

where,

Q = heat released = -1300 J

m = mass of water = 40 g

c = specific heat of water = 4.18J/g^oC      

\Delta T=\text{Change in temperature}  

T_{final} = final temperature = ?

T_{initial} = initial temperature = 91.0^oC

Now put all the given values in the above formula, we get the final temperature of water.

-1300J=40g\times 4.18J/g^oC\times (T_{final}-91.0^oC)

T_{final}=83.2^oC\approx 83^oC

Therefore, the final temperature of the water is, 83^oC
