I can help
Explanation:
Weather and Climate are incredibly similar.
They both involve rain, wind, sunshine, dryness, etc
However, your Climate would be your temperature, humidity, and atmospheric pressure.
If you ever have trouble with this kind of question, just look at weather studies, and what people do to identify things within them,
Answer:
See explanation
Explanation:
Recall that;
Speed = Distance/time
Distance = Speed * time
Speed = 200 km/h
Time = 4 hours
Distance = 200 km/h * 4 hours = 800 kilometres
Displacement has to do with distance covered in a specified direction, in this case, the direction is towards Zambales.
Hence, the displacement is 800 kilometres towards Zambales.
There are 1.456 moles of hydrogen in 5.2 moles of C7H18
Answer:
The wavelength of a sound is the distance between adjacent identical parts of a wave. The frequency is the same as that of the source and is the number of waves that pass a point per unit of time.
Answer:
44.8 L of N₂.
Explanation:
We'll begin by writing the balanced equation for the. This is illustrated below:
N₂ + 3H₂ —> 2NH₃
From the balanced equation above,
1 mole of N₂ reacted to produce 2 moles of NH₃.
Therefore, Xmol of N₂ will react to produce 4 moles of NH₃ i.e
Xmol of N₂ = (1 × 4)/2
Xmol of N₂ = 2 moles
Thus, 2 moles of N₂ reacted to produce 4 moles of NH₃.
Finally, we shall determine the volume of N₂ required for the reaction. This can be obtained as follow:
1 mole of N₂ occupies 22.4 L at STP.
Therefore, 2 moles of N₂ will occupy = (2 × 22.4) = 44.8 L
Thus, 44.8 L of N₂ is needed to produce 4 moles of NH₃.
