Answer:
This means that as pressure increases,the volume decreases or the volume increases as the temperature increases, and decreases as the temperature decreases
Answer:
5.8 moles of copper are needed to react with sulfur to produce 2.9 moles of copper (I) sulfide.
Explanation:

Moles of copper(I) sufide = 2.9 mol
According to reaction, 1 mole of copper(I) sulfide is obtained from 2 moles of copper, then 2.9 moles of copper(I) sulfide will be obtained from :
copper
5.8 moles of copper are needed to react with sulfur to produce 2.9 moles of copper (I) sulfide.
Answer:
P₂ = 28.5 torr
Explanation:
Given data:
Initial pressure = 38 torr
Initial volume = 500 L
Final volume = 677 L
Final pressure = ?
Solution:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = Initial volume
P₂ = Final pressure
V₂ = Final volume
Now we will put the vales in formula.
P₁V₁ = P₂V₂
P₂ = P₁V₁ /V₂
P₂ = 38 torr × 500 L / 667 L
P₂ = 19000 torr. L / 667 L
P₂ = 28.5 torr
Start with moles of ammonia you want to produce, then convert to how many moles of H2 you need to get one mole of ammonia, then convert that to grams :)
Answer: In the possible source of error goes: Changing two variables at once to increase rate of data collection, Taking turns with lab partners performing different tasks in an experiment, Measuring millimeters with an ordinary meter stick
In the good experimental practice goes: Measuring in standard metric units, Doing repetitive trials of the same experiment, changing the angle of a ramp in an experiment by constant intervals
Explanation: hopefully this helps i got them right so it guaaranteed you will get this right aswell.
