The photograph shows one of the boats in a science club's toy boat race. All the boats were powered by identical
rubber bands. Judges used stopwatches to time how long each rubber band took to unwind. The table shows some
of the data the judges collected.
Which boat experienced the greatest unbalanced force?
Answer:Boat P
Explanation:
Multiple all of them mass times acceleration and which ever one was the greatest was the answer. Which was Boat P 0.2436

Using the balanced chemical equation:
4NH3 + 302 --> 2N2 + 6H20
Determine the amount of grams of N2 is produced If 4.03 moles of NH3 react?
Taking into account the reaction stoichiometry, 56.42 grams of N₂ are formed when 4 moles of NH₃ react.
Reaction stoichiometryIn first place, the balanced reaction is:
4 NH₃ + 3 O₂ → 2 N₂+ 6 H₂O
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
NH₃: 4 molesO₂: 3 molesN₂: 2 molesH₂O: 6 molesThe molar mass of the compounds is:
NH₃: 17 g/moleO₂: 32 g/moleN₂: 28 g/moleH₂O: 18 g/moleThen, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
NH₃: 4 moles ×17 g/mole= 68 gramsO₂: 3 moles ×32 g/mole= 96 gramsN₂: 2 moles ×28 g/mole= 56 gramsH₂O: 6 moles ×18 g/mole= 108 gramsMass of N₂ formedThe following rule of three can be applied: if by reaction stoichiometry 4 moles of NH₃ form 56 grams of N₂, 4.03 moles of NH₃ form how much mass of N₂?
[tex]mass of N_{2} =\frac{4.03 moles NH_{3} x56 grams of N_{2} }{4 moles NH_{3}}[/tex]
mass of N₂= 56.42 grams
Then, 56.42 grams of N₂ are formed when 4 moles of NH₃ react.

Why are we able to see planets at night?
Answer: Because planets do not have nuclear fusion, they do not produce their own light. Instead, they shine with light reflected from a star. When we see planets in the night sky, such as Venus, the so-called "Evening Star," we're seeing reflected sunlight.

Using Dimensional AnalysisExplanation:Step 1: Define
[RxN - Balanced] C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
[Given] 150 g O₂
Step 2: Identify Conversions
[RxN] 5 mol O₂ → 3 mol CO₂
[PT] Molar Mass of O - 16.00 g/mol
[PT] Molar Mass of C - 12.01 g/mol
Molar Mass of O₂ - 2(16.00) = 32.00 g/mol
Molar Mass of CO₂ - 12.01 + 2(16.00) = 44.01 g/mol
Step 3: Stoich
[DA] Set up: [tex]\displaystyle 150 \ g \ O_2(\frac{1 \ mol \ O_2}{32.00 \ g \ O_2})(\frac{3 \ mol \ CO_2}{5 \ mol \ O_2})(\frac{44.01 \ g \ CO_2}{1 \ mol \ CO_2})[/tex][DA] Multiply/Divide [Cancel out units]: [tex]\displaystyle 123.778 \ g \ CO_2[/tex]Step 4: Check
Follow sig fig rules and round. We are given 2 sig figs.
