Limiting Reactant
What is a limiting reactant?
A limiting reactant is the reactant that limits the amount of product made.
What happens when the pH is lower?
When the pH is lower, the solution becomes more acidic.
What gas can cause ocean acidification?
Carbon dioxide.
What causes Acid Precipitation in most industrialized nations?
Acid precipitation in most industrialized nations is caused by pollution from burning fossil fuels.
What is the mass of 3 moles of CO2 ?
132.03 g of CO2
What happens when the limiting reactant is used up?
Once it is used up, no more products can be produced and the chemical reaction stops.
What similarities do a weak acid and a weak base have?
Both weak acids and weak bases only partially ionize in water.
What happens when the ocean gets more acidic?
The pH goes down.
Why must scientists and engineers understand Acids?
Acid precipitation harms ecosystems and damages human infrastructure.
We have 96.12g C3H8. How many moles of CO2 are produced? C3H8(g) + 5O2(g) - 3CO2(g) + 4H2O(g)
32.04 mol CO2
What is an excess reactant?
A reactant left over after the reaction.
How can a 2 acid have the same concentraion?
They can have the same concentration if both solutions contain the same amount of acid dissolved in water.
What happens to coral if the ocean becomes too acidic?
Coral cannot draw calcium from the water and may weaken or dissolve.
Where is Sulfuric Acid found?
Sulfuric acid is found in car batteries.
What is the mass of 4.5 moles of NaCl?
262.98 g of NaCl
Why is finding the limiting reactant important?
it helps find the exact amount of product made.
What does equilibrium mean?
Forward and remover reactions happen at the same rate.
How does ocean acidification affect ocean organisms?
What does (BLA + CB) mean?
Bronsted-Lowry acid + Conjugate base.
What is the molarity of a solution if 11.57g of NaOH are dissolved in enough water to make 1.50 L of solution?
0.218725 mol NaOH
Does the limiting reactant always have the smallest amount?
No, not always.
How can 2 acids can have the same strength but different pH values.
Acids can have the same strength but different pH because their concentrations are different.
Since the Industrial Revolution, what has caused ocean acidification to increase?
Increased carbon dioxide released into the atmosphere by humans.
Which 3 products contain lactic acid?
Yogurt, cheese, and sour milk
How many moles of CO2 are produced from 7.36 mol of O2 ? 2C4H10(g) + 13O2(g) - 8CO2(g) + 10H2O(g)
4.53 mol CO2
