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

For the geometric sequence, find the sum of the specified number of terms.
The first 8 terms of 4, -12, 36, ...
S8=
Answers
Given:
The geometric sequence is
[tex]4, -12, 36,...[/tex]
To find:
The sum of first 8 terms of the given geometric sequence.
Solution:
We have,
[tex]4, -12, 36,...[/tex]
Here, the first term is 4 and the common ratio is
[tex]r=\dfrac{-12}{4}[/tex]
[tex]r=-3[/tex]
The sum of first n terms of a geometric sequence is
[tex]S_n=\dfrac{a(r^n-1)}{r-1}[/tex]
Where, a is the first term and r is the common ratio.
Putting n=8, a=4 and r=-3, we get
[tex]S_8=\dfrac{4((-3)^8-1)}{-3-1}[/tex]
[tex]S_8=\dfrac{4(6561-1)}{-4}[/tex]
[tex]S_8=-6560[/tex]
Therefore, the sum of first 8 terms is -6560.

A model maker wants to make a model of a
ship
He will use a scale of 1:50
The ship was 100ft long
1 foot = 0.3 m
How long will the ship be in cm?
Answers
9514 1404 393
Answer:
60 cm
Step-by-step explanation:
The model ship will be x feet long, where ...
x/100 = 1/50
x = 100/50 = 2
In meters, that is ...
2(0.3 m) = 0.6 m
A meter is 100 cm, so the length in centimeters is ...
(0.6)(100 cm) = 60 cm
A pair of shoes that originally sold at $30 is now being offered at a 25% discount.
What is its present price?
Answers
Answer:
$22.5
Step-by-step explanation:
You will pay $22.5 for a item with original price of $30 when discounted 25%.
Answer:
Refer to explanation
Step-by-step explanation:
The screenshot you put is the correct answer, here's another method to get the same answer:
Find what 25% is.
100% = 30
1% = 30 ÷ 100 = 0.30
25% = 0.30 x 25 = 7.50
Find the price after the 25% discount.
100 - 25 = 75
75% = 30 - 7.50 = 22.50 or 0.30 x 75 = 22.50 (Both solutions give the same answer)

traveling with the current a certain boat went 24 km/h. Against the same current it only went 2 km/h. Find the current and the speed of the boat if there were no current.
Answers
Answer:
Current= 13
Speed= 11
Step-by-step explanation:
Let x represent the speed of the boat
Ley y represent the rate of current
x + y= 24......equation 1
x - y= 2...........equation 2
Using elimination method
x + y= 24
+
x - y= 2
2x = 26
x = 26/2
x = 13
Sub 13 for x in equation 1
x + y= 24
13 + y = 24
y = 24-13
y = 11
Hence the current and speed of the boat when there were no current are 11 and 13 respectively

Answers
Answer:
A
Step-by-step explanation:
Answer:
A. x = 6; v = 42
Step-by-step explanation:
Strategy : Guess and Check
Let's start with A:
If x = 6, then the first rectangle would be 12 + 42 + 6 + 12 + 42 + 6 = 120
Let's see if this checks out with the second rectangle.
6 + 42 + 42 + 6 + 42 + 42 = 180
