How many moles of NaCl are produced?
For every 2 moles of Na used, 2 moles of NaCl are produced.
How many grams is in 1 mole of chlorine in sodium chloride?
35.5 grams
What is the maximum number of moles of NaCl that can be formed?
0.394 mol
How many grams of Cl2 are produced?
23.4 g
How many grams of Cl2 can be prepared from the reaction of 16g of MnO2 and 30g of HCL?
Answer. The answer should be 14.6g.
How many grams of HCL react with 5g of MnO2?
8.39 grams
How is chlorine prepared lab?
Chlorine can be prepared in the laboratory by taking conc. Hydrochloric acid with manganese dioxide. The reaction of conc. Hydrochloric acid with manganese dioxide gives manganese di chloride, chlorine gas and water.
How chlorine is prepared from MnO2?
Chlorine is prepared in the laboratory by treating manganese dioxide (MnO2) with aqueous hydrochloric acid according to reaction. MnO2 + 4HCl→ MnCl2+Cl2+2H2O. This means, 1 mole of MnO2 comprises 87 gm of MnO2.
What reaction is calcium carbonate and hydrochloric acid?
Like all metal carbonates, calcium carbonate reacts with acidic solutions to produce carbon dioxide gas. It is this reaction that is responsible for limestone fizzing when dilute hydrochloric acid is placed on its surface.
What is the balanced symbol equation for calcium carbonate and hydrochloric acid?
Balance the Chemical Equation for the reaction of calcium carbonate with hydrochloric acid: CaCO3+ HCl -> CaCl2 + CO2 + H2O. To balance chemical equations we need to look at each element individually on both sides of the equation. To start with we can add up the elements to see which are unbalanced.
Does calcium carbonate dissolve in HCl?
Description: When calcium carbonate is added to water, it is practically insoluble. When added to acid it dissolves producing carbon dioxide. The HCl dissolves the carbonate, producing iron chloride, which is soluble.
Why does Limewater turn milky?
Calcium hydroxide is sparingly soluble in water producing an alkaline solution known as limewater. When carbon dioxide gas is passed through or over limewater, it turns milky due to the formation of calcium carbonate. Lime reacts with acidic gases like sulfur dioxide.
Which gas could turn Limewater milky white?
Carbon Dioxide Gas
Why does CO2 turns Limewater Milky what happens when excess of CO2 is passed and why?
CO2 makes limewater(calcium hydroxide) milky due to the formation of calcium carbonate. when excess of CO2 is passed, the milkiness disappears due to formation of calcium bicarbonate which is soluble in water.
Is lime acidic or basic?
“Limes” that are the green, hybrid citrus fruits are acidic with citric acid, just like lemons. Both have juice with a pH in the range of 2-3, for limes as in fruit a typical pH level is about 2.8. Hence the tart flavor for which both fruits are known.
What is the pH of Orange?
between 3
What is the pH of slaked lime?
12.8
What is the pH of CaO?
12.5
What is the pH of quicklime?
12.4
What is the pH of h2so4?
pH of Common Acids and Bases
| Acid | Name | 1 mM |
|---|---|---|
| H2SO4 | sulfuric acid | 2.75 |
| HI | hydroiodic acid | 3.01 |
| HBr | hydrobromic acid | 3.01 |

What is the pH of weak bases?
Weak Bases The pH of a weak base falls somewhere between 7 and 10. Like weak acids, weak bases do not undergo complete dissociation; instead, their ionization is a two-way reaction with a definite equilibrium point.
What is the pH of 0.01 m h2so4?
1.699
What is the pH of 98% sulfuric acid?
about 0.1
What is the most powerful acid?
fluoroantimonic acid
What acid has a pH of 1?
The pH scale
| Increasing pH (Decreasing Acidity) | Substances |
|---|---|
| 0 (most acidic) | Hydrochloric acid (HCl) |
| 1 | Stomach acid |
| 2 | Lemon juice |
| 3 | Cola, beer, vinegar |
What are 7 strong acids?
There are 7 strong acids: chloric acid, hydrobromic acid, hydrochloric acid, hydroiodic acid, nitric acid, perchloric acid, and sulfuric acid. Being part of the list of strong acids doesn’t give any indication of how dangerous or damaging an acid is though.
What are 3 weak acids?
Some common examples of weak acids are listed below.
- Formic acid (chemical formula: HCOOH)
- Acetic acid (chemical formula: CH3COOH)
- Benzoic acid (chemical formula: C6H5COOH)
- Oxalic acid (chemical formula: C2H2O4)
