Answer:

<h2>x = - 2</h2><h2 />

Explanation:

<u>3 (x - 2)</u> = x - 1

   4

3x - 6 = 4x - 4

3x - 4x = 6 - 4

x = - 2

proof:

<u>3 ((-2) - 2)</u> = (-2) - 1

Answer:

-2

Explanation:

3/2 (x-2) = x-1

<=> 3/4 x - 3/2 = x-1

<=> 3/4 x - x = 3/2 -1

<=> -1/4 x =1/2

<=> x= -2

8. Zeolite is used to remove moisture from methane. A vertical column is filled with 1000.0 kg of dry zeolite. The zeolite has t
Natasha_Volkova [10]

Answer:

Follows are the solution to this question:

Explanation:

Methane inlet humidity content of =7.00\%

Methane moisture outlet content =0.05\%

Zeolite absorption humidity = 6.95\%

Dry zeolite 1 kg will accommodate water= 0.1000 \ kg

One kilogram of Dry Zeolite will carry water from =0.1000\ kg

The water can contain 1000 kg of zeolite = 100 \ kg

Methane which would be made =\frac{100}{6.95\%}= 1,439 \ kg

That's why it will be producing 1439 kg of methane.

Please help me with this chemistry question. Image attached.
Leya [2.2K]

Answer:

Moles of zinc chloride produced are 0.09942 moles.

Explanation:

Zn+2HCl\rightarrow ZnCl_2+H_2

Mass of zinc used = 6.5 g

Moles of zinc =\frac{6.5 g}{65.38 g/mol}=0.09942 mol

According to reaction, 1 mol of zinc gives 1 mole of zinc chloride,then 0.09942 moles of zinc will give :

\frac{1}{1}\times 0.09942 =0.09942 mol of zinc chloride

Moles of zinc chloride produced are 0.09942 moles.

What is the [h3o ] for a solution of seawater at 25°c that has a ph of 8.3?
Kipish [7]
PH of solution at 25ºC = 8.3

[ H_3O^+] = 10 ^{-pH}

{H_3O^+] = 10 ^{-8.3}

[H_3O^+] = 5.011*10^{-9}  M

hope this helps!
