Answer:
44.2 L
Explanation:
Use Charles Law:

We have all the values except for V₂; this is what we're solving for. Input the values:
- make sure that your temperature is in Kelvin
From here, we need to get V₂ by itself. To do this, multiply by 273 on both sides:

Therefore, V₂ = 44.2 L
It's also helpful to know that temperature and volume are linearly related. So, when temperature drops, so will volume and vice versa.
Answer:
dude! it's static!
Explanation:
a dry cell can't function and is therefore static!
Today scientist don't believe there's life in this solar system but there is proof of living things that once used to live on mars. there might be life in our universe and other galaxies.

Answer:
91%
Explanation:
Since you are just trying to find the yield, take the moles of the substance from the products and divide it by the mol value of the reactants. Multiply by 100 to find percentage
0.45 ÷ 0.41 = 0.91111...
91%
