Ammonium magnesium phosphate hexa-hydrate usually looses its water of crystallization in a gradual manner. At the temperature above 100 degree Celsius the compound would have lost all its water of crystallization.<span />

Answer:

T = 100 C (212 F)

Explanation:

'Water of hydration' is the terminology used to refer to the water molecules present in the crystals of a given substance that can be removed by heating the substance without altering its composition.

MgNH4PO4.6H2O is essentially magnesium ammonium phosphate which has  6 molecules of water of hydration. These can be removed stepwise by gradually increasing the temperature. At a final temperature of 100 C or 212 F the compound will lose all water of hydration.

How many gallons of concentrated sulfuric acid (density of 1.84 g/cm3) are required to have a mass of 184.33 pounds?
KengaRu [80]

After series of conversion from one unit to another, the number of gallons was found to be 12 litres

<h3>Density, Mass and Volume</h3>

Given Data

  • Density of Sulfuric acid = 1.84 g/cm3
  • Mass of Sulfuric acid = 184.33 Pounds

Conversion from pounds to Gram

1 kg ---------2.204 lb

x kg ---------184.33 lb

x = 184.33/2.204

x = 83.634 kg

hence the mass in gram = 83.634*1000

mass in gram = 83634 g

Now let us find the volume

We know that density = mass/volume

volume = mass/density

volume = 83634/1.84

volume = 45453.26 cm^3

Convert cm^3 to litres

Volume in litres = 45453.26 /1000

Volume in litres = 45.45 Litres

Convert from Litres to Gallons

1 gallon = 3.79 L

x gallons =  45.45 L

x =  45.45/3.79

x gallons = 11.99 L


Approx = 12 Litres

The electron pair in a C-F bond could be considered Question 3 options: closer to C because carbon has a larger radius and thus
Leokris [45]

Answer:

closer to F because fluorine has a higher electronegativity than carbon

Explanation:

Electronegativity refers to the ability of an atom in a bonding situation to draw the shared electrons of the bond closer to itself.

Electronegativity increases across the period and decreases down the group. A highly electronegative atom draws the shared electron pair of a bond towards itself.

When two atoms are bonded together, the electron pair is always drawn closer to the atom that has a higher electronegativity.

Hence, the electron pair in a C-F bond could be considered closer to F because fluorine has a higher electronegativity than carbon.
