Answer: #1 The poppy seeds represent the protons, electrons and neutrons
#2 The fiberfill represents the nucleus #3 Protons and neutrons are in the nucleus #4 Electrons are the particles that are surrounding the nucleus #5 Because they are representing different things and they are their own entity
Hope this really does help! : ⊃
Because the coldness in the ice cream and the suns gamma rays are hitting the ice cream and then it will start to melt. and that is why ice cream melts.
Explanation:
Sodium hydroxide completely ionizes in water to produce sodium ions and hydroxide ions. Hydroxide ions are in excess and neutralize all acetic acid added by the following ionic equation:
The mixture would contain
if undergoes no hydrolysis; the solution is of volume after the mixing. The two species would thus be of concentration and , respectively.
Construct a RICE table for the hydrolysis of under a basic aqueous environment (with a negligible hydronium concentration.)
The question supplied the <em>acid</em> dissociation constant for acetic acid ; however, calculating the hydrolysis equilibrium taking place in this basic mixture requires the <em>base</em> dissociation constant for its conjugate base, . The following relationship relates the two quantities:
... where the water self-ionization constant under standard conditions. Thus . By the definition of :
Answer:
They form crystals, they have really high boiling points, They have higher enthalpies of fusion and vaporize than an molecular compound, the are brittle
