Explanation:
The molecules of solids are shrinked in there normal state . but as a heat energy is produced , the molecules starts curating fast and fast as temperature goes up . since they vibrate , they hit and collide each other breaking the bondings this increases the surface of area of the solid , and molecules consumes that space and they expand .
Answer:
no of moles = (mass) ÷ molar mass
you get the molar mass from the periodic table
n = 20.0g ÷ ( 149.09 g/mol )
= 0.134 mol
number of formula units = number of moles × (6.022×10^23)
= 8.07×10^22 units
number of hydrogen atoms in (NH4)3 PO3 = 12 × number of formula units
= 9.68×10^23 hydrogen atoms
Being at the beach: Joyous, thrilled - Smiling, jumping (for joy)
Seeing a tornado nearby: Terror, despair - Crying, shaking
Crossing paths with a grizzly bear: Doom, hopelessness - Frozen, sweating
Skydiving: Anxious, excited - Fidgeting, nervous laughter
Noticing a suspicious figure...: Suspicious, frightened - Observing, running
Seeing a neighbors house on fire: Pity, distress - Frowning, shaking
Seeing two dogs..: Affectionate, happiness - Smiling, giggling
Receiving money: Surprised, relieved - Jumping for joy, crying
Fight or flight response, tornado, grizzly bear, fire, suspicious figure, - maybe skydiving if you chicken out?
These are all opinions though hopefully this helps.
Answer:
1.) The result is a red solution and a blue-green precipitate.
2.) The reaction results in a precipitate of a basic salt, which can co-precipitate with other metal ions that form hydroxide precipitates, causing complications when trying to separate metal ions.
