When wood burns it makes 1 ash and 2 CO and so law of conversation matter wouldn't be violated as the ash + the smoke each would have a fraction of the original matter from the wood
Answer:
Molarity = 0.3 M
Explanation:
Given data:
Moles of NaOH = 0.720 mol
Volume of water = 2.40 L
Molarity = ?
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
Molarity = 0.720 mol / 2.40 L
Molarity = 0.3 mol/L
Molarity = 0.3 M
V₂=0.894 L
<h3>Further explanation</h3>
Given
V₁=1.55 L
T₁=27 + 273 = 300 K
P₁=1 atm
T₂=-100+273 = 173 K
Required
The final volume(V₂)
Solution
Charles's Law
When the gas pressure is kept constant, the gas volume is proportional to the temperature
Input the value :
V₂=V₁T₂/T₁
V₂=1.55 x 173/300
V₂=0.894 L
I can’t see the image, can you name some of the energy resources under this comment?
Waterways or lakes. at least that’s what google said lol.
