Tammy’s bush would have 30 blooms. 80% of 30 is 24.
The difference is 10 because its asking you to subtract ( 6 - (-4) = 10 ).
The volume of cup A is 1570.8 cm³ while the volume of cup B is 6283 cm³
<h3>
Volume</h3>
Volume is the amount of space occupied by a three dimensional object or figure.
The cup has the shape of a cylinder, the volume is:
Volume = π * radius² * height
For cup A:
Volume = π * (10/2)² * 20 = 1570.8 cm³
Let each punch be 1 cm³, the number of cups needed = 1570.8 cm³ / 1 cm³ = 1571
For cup B:
Volume = π * (20/2)² * 20 = 6283 cm³
Let each punch be 1 cm³, the number of cups needed = 6283 cm³ / 1 cm³ = 6283
The volume of cup A is 1570.8 cm³ while the volume of cup B is 6283 cm³

I really hope this is right, it was kinda confusing! Sorry if I got it wrong!!
The enthalpy change (ΔH) for the reaction given the data from the question is –900.8 KJ
<h3>Data obtained from the question</h3>
- 4NH₃ + 5O₂ —> 6H₂O + 4NO
- Enthalpy of ammonia, NH₃ = –46.2 KJ
- Enthalpy of Oxygen = 0 KJ
- Enthalpy of water, H₂O = –241.8 KJ
- Enthalpy of nitric oxide, NO = 91.3 KJ
- Enthalpy change (ΔH) =?
<h3>How to determine the enthalpy change</h3>
ΔHrxn = ∑ΔH(products) - ∑ΔH(reactants)
ΔHrxn = ∑[H(H₂O) + H(NO)] - ∑[H(NH₃) + H(O₂)]
ΔHrxn = [(6 × –241.8) + (4 × 91.3)] – [(4 × –46.2) + (5×0)]
ΔHrxn = –1085.6 + 184.8
ΔHrxn = –900.8 KJ
