I hope it helps, make sure of the answer before answering
Acceleration means that while it's falling, its speed will increase by 9.8 m/s
every second. That's the acceleration of everything that falls near the Earth's
surface, no matter how heavy or light the object is.
In 0.67 seconds, then, the speed of the acorn increases from zero to
(0.67 x 9.8) = <u>6.57 m/s</u> .
Technically the are both right and wrong. Solid substances are most likely to sublime is they have... high vapor pressure and weak intermolecular forces.
I would say the match because it has a higher temperature but I kinda feel it’s A ice cube because it’s to much of an easy question
3.5 moles of ammonia (NH₃) are produced
Explanation:
We have the following chemical reaction where hydrogen (H₂) reacts with nitrogen (N₂) to produce ammonia (NH₃):
3 H₂ + N₂ → 2 NH₃
number of moles = mass / molecular weight
number of moles of N₂ = 48.97 / 28 = 1.75 moles
We see from the chemical reaction that 1 mole of N₂ will react with 3 moles of H₂, so 1.75 moles of nitrogen will react with 3 × 1.75 = 5.25 moles of H₂. We have 7.32 moles of H₂, a quantity more of what is needed, so the limiting reactant is N₂.
Knowing this we devise the following reasoning:
if 1 mole of N₂ produces 2 moles of NH₃
then 1.75 moles of N₂ produces X moles of NH₃
X = (1.75 × 2) / 1 = 3.5 moles of NH₃
