The Earth's crust or is it the continental plates one of the two but they push against each other costing a tsunami.
Answer:
= 9.28 g CO₂
Explanation:
First write a balanced equation:
CH₄ + 2O₂ -> 2H₂O + CO₂
Convert the information to moles
7.50g CH₄ = 0.46875 mol CH₄
13.5g O₂ = 0.421875 mol O₂
Theoretical molar ratio CH₄:O₂ -> 1:2
Actual ratio is 0.46875 : 0.421875 ≈ 1:1
If all CH₄ is used up, there would need to be more O₂
So O₂ is the limiting reactant and we use this in our equation
Use molar ratio to find moles of CO₂
0.421875 mol O₂ * 1 mol CO₂/2 mol O₂=0.2109375 mol CO₂
Then convert to grams
0.2109375 mol CO₂ = 9.28114 g CO₂
round to 3 sig figs
= 9.28 g CO₂
Answer:are there any answer option? cause i know but i have to make sure
Explanation:
The answer is Argon (Ar).
First, need to know the formula of Molarity.
moles of solute
Molarity = ---------------------------
liters of solution
Given
2.0 liter of solution
58 grams of NaCl
Base of my research the moles of 58 grams of NaCl is 0.750 moles
Solution
0.750 moles
Molarity = ----------------------- = 0.375
2.0 L
The molarity of this solution is 0.375
