True, this is because they are too small to be studied as if they were an animal, plant, or geological formation such as a rock or crystal.
Answer:
2200J
Explanation:
Given parameters:
Specific heat of aluminum = 0.88J/g°C
Mass of nugget = 50g
Initial temperature = 20°C
Final temperature = 70°C
Unknown:
Quantity of heat required for the heating = ?
Solution:
To solve this problem, we use the expression below;
H = m c Δt
H is the quantity of heat
m is the mass
c is the specific heat capacity
Δt is the change in temperature
H = 50 x 0.88 x (70 - 20) = 2200J
Answer:
0.767 moles of ammonium phosphate are produced
Explanation:
The reaction of ammona (NH3), with phosphoric acid is:
3 NH3 + H3PO4 → (NH4)3PO4
<em>Where 3 moles of ammonia reacts per mole of H3PO4 to produce 1 mole of ammonium phosphate.</em>
<em />
If 2.3 moles of ammonia reacts, the moles of ammonium phosphate produced if phosphoric acid is in excess are:
2.3 moles NH3 * (1 mole (NH4)3PO4 / 3 moles NH3) =
<h3>0.767 moles of ammonium phosphate are produced</h3>
<em />
