Answer 1

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

describe the relationship between the amount of C-15 and time?

Answers

Answer:

As time increases, C-15 (Carbon) decreases. During radioactive decay, the amount of Carbon in a substance undergoes half-lives (A sample could have  a half life of 1002 years, for example.) When that substance ages to that timeframe, it loses half of its mass. Then for the next half-life, it loses half of that new mass, and so on.

Your classmate is viewing a sample using high power and is about to refocus using the coarse adjustment knob. What would you recommend your classmate do and why?

Answers

Answer:

Using the coarse adjustment knob of the microscope in high power may lead to the breaking of the slide if adjusted and raised the slide too much which can damage the sample as well as the high power lens.

In this case, I would recommend using the fine adjustment knob and moving away from the end of the viewing area of the microscope so there would no collision take place. The fine adjustment will help to get a clear image.

In naming the compound PCl5, the prefix used with the second element is ____________________.

Answers

Answer:

[tex]\boxed {\boxed {\sf Hepta}}[/tex]

Explanation:

We are given the formula:

[tex]PCl_5[/tex]

This is a molecular formula, because it contains nonmetals.

1. Name the first element

The first element is phosphorous (P). Since this is the first element and there is only one, we don't need a prefix.

Phosphorous

2. Second element

The second element is chlorine (Cl). It has a subscript of 5, so we must add the prefix of hepta-.

Phosphorous heptachlorine

Add the ending of -ide.

Phosphorous heptachloride

The prefix used for the second element is hepta. The compound name is phosphorous heptachloride.

Answers

Answer:

The periodic table is a set of elements organized by their atomic number, from lowest (hydrogen 1) to highest (oganesson 118). That number is the amount of protons in the nucleus of an atom of the element. The table is split into three groups of elements (metals, nonmetals and metalloids). As you go down the table the elements are more reactive.

For the reaction 2NH3(g) + O2(g) -> 2NO(g) + 3H2O(g). The reaction is run using 824 g NH3 and excess oxygen. How many moles of NO are formed? How many moles of H2O are formed?

Answers

Answer:

Explanation:

Step One

Find the molar Mass of NH3

N =   14

3H =  3

Mass = 17

Step Two

Find the number of moles of NH3

mols = given mass / Molar Mass

given mass = 824 grams

molar mass = 17

mols = 824/17

mols =  48.47

Step Three

Find the moles of NO

Here you have to look at the balanced equation

Every 2 mols of HN3 produces 2 mols of NO

So the number of mols of NH3 = 48.47

The number of mols of  NO      = 48.47

Step Four

Find the mols of H2O

2 mols of NH3 produces 3 moles of H20

48.47 mols H20 produces x moles of H20

3/x = 2/48.47     Cross Multiply

2x = 3*48.47

2x = 145.41         Divide by 2

x = 145.41/2

x = 72.71            mols of water.

A student need to predict the mass of a block of aluminum. The block is 4.23 cm on all sides and the density of aluminum is 2.7 g/cm3. What will the mass of the block be?

Answers

The equation for density is:
Density = mass / volume.
To rearrange for mass, you would times by volume on both sides to give you:
Mass = density x volume
Mass = 2.7 x (4.23^3)
= 2.7 x 75.686967
= 204.3548109
= 204.35 g (to 2 dp)

volume of 5.2 X 10^26 molecules of CH4

Answers

Answer:

19348.84 L

Explanation:

At STP, we know that;

6.02 × 10^(23) molecules = 22.4 L

Therefore, 5.2 × 10^(26) molecules = 5.2 × 10^(26) × 22.4/(6.02 × 10^(23)) = 19348.84 L

Thus, volume of CH4 with 5.2 X 10^26 molecules is 19348.84 L

Two balloons are given an electrostatic charge by rubbing them with a wool cloth. Which observation provides evidence of the force that the balloons exert on each other over a distance because of their charge?

Answers

Answer:

C. Moving Balloon 1 can make Balloon 2 move without the balloons touching.

Explanation:

When two balloons are rubbed with a wool cloth, they get electrostatic charge and both become negatively charged.

If both balloons will be place close together, balloon 1 will push the balloon 2 far from itself without touching it as they both are negatively charged and things with same charges repel each other.

Hence, the correct answer is "C. Moving Balloon 1 can make Balloon 2 move without the balloons touching."
