If you wanted to test what will happen if salt was added to water then frozen that is when you will use scientific investigation.
Answer:
11.6 L will be the number of liters of carbon dioxide measured at STP.
Explanation:
The balanced equation for this combustion reaction is:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
where 1 mol of propane reacts to 5 moles of oxygen in order to produce 3 moles of carbon dioxide and 4 moles of water.
We assume the oxygen in excess, so the limiting reagent is the propane. Now, we determine the moles: 7.65 g . 1 mol/ 44 g = 0.174 moles
Ratio is 1:3. 1 mol of propane can produce 3 moles of CO₂
Therefore, 0.174 moles will produce (0.174 . 3) / 1 = 0.521 moles of CO₂
As 1 mol of gas is contained in 22.4L at STP conditions, we propose
22.4L / 1 mol = V₂ / 0.521 mol
22.4 L / 1 mol . 0.521 mol = V₂ → 11.6 L
Explanation:
A salt is form from the reaction between an acid and a base
This is an incomplete question, here is a complete question.
Calculate the volume in milliliters of a 1.29 mol/L iron(II) bromide solution that contains 275 mmol of iron(II) bromide . Round your answer to significant 3 digits.
Answer : The volume of iron(II) bromide solution is, 
Explanation : Given,
Concentration of iron(II) bromide = 1.29 mo/L
Moles of iron(II) bromide = 275 mmol = 0.275 mol
conversion used : 1 mmol = 0.001 mol
Now we have to calculate the volume of iron(II) bromide.
Now put all the given values in this formula, we get:
Thus, the volume of iron(II) bromide solution is,
