The frequency of collisions between the N₂ and H₂ molecules will decrease and the rate of reaction will also decrease.
Since the water is cooler than the gas mixture, heat will flow from the gas to the water.
The gas will cool down, so the average kinetic energy of the gas molecules will decrease.
The molecules will be moving more slowly, so there will be <em>fewer collisions</em> and <em>fewer of these collisions will have enough energy to react</em>.
The rate of reaction between H₂ and N₂ molecules at room temperature is exceedingly slow, <em>but cooling the gas mixture will make the reaction even slower</em>.
Answer:
a. 4900 mL; b. 4900 cm³ c. 4.9x10⁻³ m³
Explanation:
1 L = 1 dm³
4.9 L = 4.9 dm³
1 dm³ = 1000 cm³ → 4900 cm³
1 cm³ = 1 mL (4900 mL)
1 dm³ = 1x10⁻³ m³ → 4.9x10⁻³ m³
The blank space in the task statement should be filled with 25 as methane can retain 25 times more heat than carbon dioxide.
<h3>Heat Retention: Methane and Carbon dioxide</h3>
Methane, carbon dioxide amongst other gases are important greenhouse gases which allows the Earth retain it's heat in order for it to be habitable.
Methane can retain and release about 25 times more heat than Carbon Dioxide although Methane emissions are lower compared to Carbon Dioxide.

The answer would be D, all the above
Answer:
16.9 mol
Explanation:
8Al + 3Fe₃O₄ ⟶ 4Al₂O₃ + 9Fe
You want to convert moles of Fe₃O₄ to moles of Al.
The molar ratio is 8 mol Al:3 mol Fe₃O₄. Calculate the moles of Al
Moles of Al = 6.34 × 8/3
Moles of Al = 6.34 × 2.667
Moles of Al = 16.9 mol Al
