How many grams of aluminum hydroxide are produced when 8 moles of aluminum sulfite react in excess sodium hydroxide ?

Answers

Answer:

Number of moles Aluminium sulfide

1 mole of sulfide contains 150 g

Therefore; 16.2/150  

              = 0.108 moles  

The mole ratio of Al2S3 : Al(OH)3 is 1:2

Therefore; moles of Aluminium hydroxide will be;

 = (0.108 × 2)

 = 0.216 moles  

But, 1 mole of  Al(OH)3 contains 77 g

Therefore, the mass of aluminium hydroxide is

  0.216 moles × 77

=  16.632 g

Michael drove from home to work at an average speed of 50 mph. His return trip home took 30 minutes longer because he could only drive at 40 mph. Find the distance from his home to his work. A. [3 pts) Define variables to represent the unknowns and setup the necessary equations to answer the question. B. [4 pts) Algebraically solve the equation you created and express your final answer using a complete sentence and appropriate units. (You will not receive full credit if a trial and error method is used in place of an algebraic method.)

Answers

Answer:

100 miles

Step-by-step explanation:

Given :

To work :

speed = 50mph

Let time taken = x

From work :

speed = 40mph

30 minutes = 30/60 = 0.5

Time taken = x + 0.5

Distance from home to work :

Distance = speed * time

To work distance = from work distance

This can be algebraically expressed as :

50 * x = 40(x + 0.5)

50x = 40x + 20

50x - 40x = 20

10x = 20

x = 20/10

x = 2

Hence,

Distance = 50 * 2 = 100

The the distance from home to work = 100 miles

The distance from Michael home to work is 100 miles

Speed

Speed is the ratio of the total distance travelled to the total time taken. It is given by:

Speed = distance / time

Let d represent the distance from Michael home to work. Hence:

50 = d/tt = d / 50

He took 30 minutes (0.5 hours) longer when driving at 40 mph, hence:

40 = d/(t + 0.5)t = (d - 20)/40

d/50 = (d - 20) / 40

40d = 50d - 1000

10d = 1000

d = 100 miles

The distance from Michael home to work is 100 miles

3(1.5x+9)= tell me NOW

Answers

Answer:

x = -6

Step-by-step explanation:

Simplifying

3(1.5x + 9) = 0

Reorder the terms:

3(9 + 1.5x) = 0

(9 * 3 + 1.5x * 3) = 0

(27 + 4.5x) = 0

Solving

27 + 4.5x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-27' to each side of the equation.

27 + -27 + 4.5x = 0 + -27

Combine like terms: 27 + -27 = 0

0 + 4.5x = 0 + -27

4.5x = 0 + -27

Combine like terms: 0 + -27 = -27

4.5x = -27

Divide each side by '4.5'.

x = -6

Simplifying

x = -6

Answers

Answer:

DVD sales have been on the decline for over a decade, but a slew of new streaming services and a shift in how consumers are watching movies and TV shows could be the final death knell for the technology.

The same can be said for Blu-Ray discs.

At its peak, DVD sales reached $16.3 billion and were 64% of the U.S. home video market. That was 2005. These days, DVD sales account for less than 10% of the total market, with total sales hitting $2.2 billion in 2018.

Blu-Ray discs, which have always been slightly more expensive than DVDs, launched in 2006. At most, Blu-Ray sales reached $2.37 billion in 2013, before falling to $1.8 billion in 2018. It’s likely that Blu-Ray sales fractionally impacted the decline of DVD sales, but the fact that DVD sales still outpace Blu-Ray sales shows it’s not the real culprit.

Instead, a combination of the Great Recession, a rise in customers buying on-demand and digital copies of films and the launch of streaming services is what has caused DVD sales to decline more than 86% in the last 13 years.

Answer:

[tex]Total = 2.35n[/tex]

Step-by-step explanation:

Given

Monday = n

Tuesday = 90% of Monday

Wednesday = 50% of Tuesday

Required

Determine the total miles

We have:

Tuesday = 90% of Monday

Substitute n for Monday

Tuesday = 90% of n

[tex]Tuesday = 90\% * n[/tex]

Express percentage to decimal

[tex]Tuesday = 0.90 * n[/tex]

[tex]Tuesday = 0.90n[/tex]

We also have that:

Wednesday = 50% of Tuesday

Wednesday = 50% * Tuesday

Substitute 0.90n for Tuesday

[tex]Wednesday = 50\% * 0.90n[/tex]

Express percentage to decimal

[tex]Wednesday = 0.50 * 0.90n[/tex]

[tex]Wednesday = 0.45n[/tex]

The total number of miles is:

[tex]Total = Monday + Tuesday + Wednesday[/tex]

[tex]Total = n + 0.90n + 0.45n[/tex]

[tex]Total = 2.35n[/tex]

Step-by-step explanation:

The Pythagorean Theorem states that the two shorter sides of a right triangle squared and added together will equal the longest side (hypotenuse) of the right triangle squared. The longest side of this right triangle is 4, 4 squared is 16. The two shorter sides of the right triangle are 2 and [tex]2\sqrt{3}[/tex], squared individually would be 4 and 12, and added together they also equal 16. These sides are a valid input for the Pythagorean Theorem, so these three sides are the sides of a right triangle. 2 and [tex]2\sqrt{3}[/tex] being the legs of the right triangle, and 4 being the hypotenuse.
