Potassium is not found  free in nature but is found in the form of potash. Potash is the ore of potassium and this ore is mined from deep down the earth or can sometimes  be found on the surface. Potash was mostly formed as sea water receded and left deposits.

Potash is usually in the form of potassium salts such potassium chloride and  potassium sulphate.  The potash  is mined then taken to the factory where it is crushed and purified  by removing such impurities as clay.

The now purified potassium salts are subjected to a process called electrolysis where  potassium metal is obtained from its salt.

Grasslands are a biome that receives 25-75 cm of rain each year and contain what?
s2008m [1.1K]

Answer:

<h3><em>A is most likely your correct answer</em></h3>

Explanation:

A. Hills Covered with dry brush- this is most likely correct

b. Hills covered in lush grass- incorrect, because it is LUSH grass which would require lots of rain.

c. Flat lands with little grass- incorrect because grasslands DO have lots of grass.

D- incorrect because grasslands typically do NOT have rocky mountains <u>but are generally flatlands with grass</u>

In a coffee cup calorimeter, 1.60 g of NH4NO3 is mixed with 75.0 g of water at an initial temperature of 25.00 degrees C. After
igomit [66]

Answer:

+26.6kJ/mol

Explanation:

The enthalpy of dissolution of NH₄NO₃ is:

NH₄NO₃(aq) + ΔH  → NH₄⁺ + NO₃⁻

Where ΔH is the heat of reaction that is absorbed per mole of NH₄NO₃,

The moles that reacts in 1.60g are (Molar mass NH₄NO₃:80g/mol):

1.60g * * (1mol / 80g) = 0.02 moles reacts

To find the heat released in the coffee cup calorimeter, we must use the equation:

Q = m×ΔT×C

Where Q is heat released,

m is mass of the solution

ΔT is change in temperature (Final temperature - Initial temperature)

C is specific heat of the solution (4.18J/g°C)

Mass of the solution is:

1.60g + 75g = 76.60g

Change in temperature is:

25.00°C - 23.34°C = 1.66°C

Replacing:

Q = m×ΔT×C

Q = 76.60g×1.66°C×4.18J/g°C

Q = 531.5J

This is the heat released per 0.02mol. The heat released per mole (Enthalpy change for the dissolution of NH₄NO₃) is:

531.5J / 0.02mol = 26576J/ mol =

+26.6kJ/mol

<em>+ because the heat is absorbed, the reaction is endothermic-</em>

Wine goes bad soon after opening because the ethanol CH3CH2OH dissolved in it reacts with oxygen O2 gas to form water and aqueou
lara [203]

Answer:

1.70 mol of ethanol is needed

Explanation:

First, we have to write the balanced equation for reaction of ethanol with oxygen to produce acetic acid and water

Balanced reaction:

CH_{3}CH_{2}OH+O_{2}\rightarrow CH_{3}COOH+H_{2}O

According to balanced equation, 1 mol of ethanol produces 1 mol of H_{2}O

So, moles of ethanol needed to produce 1.70 mol of water = 1.70 mol
