I'm not completely sure but if I did know I would definitely tell u
Answer:
To tell if something is an acid or a base, you can use a chemical called an indicator. An indicator changes color when it encounters an acid or base. There are many different types of indicators, some that are liquids and others that are concentrated on little strips of "litmus" paper.
Explanation:
Answer:
the property that is shared between liquids us called thermometric property your welcome
Explanation:
Reduction is a chemical reaction in which electrons are gained by one of the atoms taking part in the reaction and lowering of an oxidation state of that atom.
Reduction takes place at the cathode.
In aqueous, vanadium(V) is present in +5 oxidation state which on reduction changes to vanadium(I) with +1 oxidation state.
The half reaction is :
Answer:
Percentage yield = 57.57%
Explanation:
Given data:
Actual yield of carbondioxide = 38.0 g
Mass of propane = 22.05 g
Percentage yield = ?
Solution:
Chemical equation:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
Number of moles of propane:
Number of moles of propane = mass / molar mass
Number of moles of propane = 22.05 g/ 44 g/mol
Number of moles of propane = 0.5 mol
Now we compare the moles of carbon dioxide with moles of propane.
C₃H₈ : CO₂
1 : 3
0.5 : 3×0.5 = 1.5 mol
Mass of carbondioxide:
Mass of carbondioxide = moles × molar mass
Mass of carbondioxide = 1.5 mol × 44 g/mol
Mass of carbondioxide = 66 g
Percentage yield:
Percentage yield = actual yield / theoretical yield × 100
Percentage yield = 38 g/ 66 g × 100
Percentage yield = 57.57%
