When sodium metal is added to water an orange flame is observed on the metal surface. Based on this observation what can best be concluded?
The observation of an orange flame when sodium metal is added to water indicates the release of energy in the form of light. This suggests that a chemical reaction is taking place between the sodium and water, likely producing sodium hydroxide and hydrogen gas.
If 40 grams of sodium hydroxide and 3 grams of hydrogen gas are produced when 27 grams of sodium metal is consumed how many grams of liquid water must have been added?
Using stoichiometry, we can calculate that 27 grams of sodium metal reacting with water produces 40 grams of sodium hydroxide. Since 40 grams of sodium hydroxide were produced, this correlates to 27 grams of sodium being consumed. Therefore, the water added should be the difference between the initial weight of sodium (27 grams) and the weight of sodium left (0 grams) after the reaction, resulting in 27 grams of water being added.
Sodium fizzes when added to water. But why doesn't sodium chloride fizz when added to water?
Sodium fizzes in water because it is undergoing a chemical reaction with water to form sodium hydroxide. The result is more stable than either of the original chemicals. When sodium chloride is added to water both of these substances are stable with respect to each other and no reaction occurs that results in a new chemical product.
Water reacts with sodium metal to produce sodium hydroxide and hydrogen gas along with heat and light. What are the reactants in this chemical reaction?
The reactants in this chemical reaction are water and sodium metal.
What gas is produced when Sodium metal reacts violently with water to produce sodium hydroxide and a gas that pops in the presence of a burning splint?
The gas produced is hydrogen gas (H2). The reaction between sodium metal and water is a highly exothermic reaction that liberates hydrogen gas, which in turn reacts explosively with oxygen in the air when ignited by a burning splint.
What alkali is produced when sodium chloride is added to water?
Sodium chloride is dissociated in water in Na+ and Cl-. Sodium is an alkali metal.
What gas is produced from the reaction when sodium is added to water?
Hydrogen gas is produced when sodium is added to water. This reaction is highly exothermic and can result in the sodium igniting.
Why Sodium metal is not treated with water?
Sodium is an unstable element which reacts violently when in contact with water. Sodium added to water can result in explosions.
What compounds are produced when sodium nitrate is added to a mixture of water and ethanol?
When sodium nitrate is added to a mixture of water and ethanol, it dissociates into sodium ions and nitrate ions. No new compounds are formed.
What gas is produced when NaCl is added to water?
Sodium chloride is soluble in water but don't react with water.
When sodium oxide is added to water sodium hydroxide is produced?
When sodium oxide is added to water, it reacts to form sodium hydroxide as a product. This is because sodium oxide is a basic oxide that reacts with water to produce a strong base, sodium hydroxide, along with the release of heat. This reaction is exothermic and can be used in industries for the production of sodium hydroxide.
When sodium metal is added to water an orange flame is observed on the metal surface. Based on this observation what can best be concluded?
The observation of an orange flame when sodium metal is added to water indicates the release of energy in the form of light. This suggests that a chemical reaction is taking place between the sodium and water, likely producing sodium hydroxide and hydrogen gas.
Is the gas produced when sodium mixes with water a physical change or chemical change?
It is a chemical change, as sodium cannot evaporate (or water go to water vapor) without added heat. The main gas produced in this highly exothermic chemical reaction is hydrogen, liberated from the water by the combination of a hydroxide radical (OH) with the sodium, yielding a sodium hydroxide (NaOH) solution. The heat released is typically sufficient to ignite and burn both the sodium and the released hydrogen. So pure sodium metal oddly appears to catch fire and burn when placed in water.
What is added to sodium hydroxide that will get sodium sulphate and water?
You would need to add Sulphuric acid to make Sodium Sulphate + Water :)
If 40 grams of sodium hydroxide and 3 grams of hydrogen gas are produced when 27 grams of sodium metal is consumed how many grams of liquid water must have been added?
Using stoichiometry, we can calculate that 27 grams of sodium metal reacting with water produces 40 grams of sodium hydroxide. Since 40 grams of sodium hydroxide were produced, this correlates to 27 grams of sodium being consumed. Therefore, the water added should be the difference between the initial weight of sodium (27 grams) and the weight of sodium left (0 grams) after the reaction, resulting in 27 grams of water being added.
What gas is produced when sodium and sulphuric react?
When sodium metal reacts with sulfuric acid (H2SO4), hydrogen gas (H2) is produced in addition to sodium sulfate (Na2SO4) and water (H2O). Sodium displaces hydrogen from sulfuric acid to form hydrogen gas.
Why doesnt sodium chloride fizz when added to water?
Sodium chloride (table salt) does not fizz when added to water because it is a stable compound that does not undergo a chemical reaction with water. When dissolved in water, sodium chloride dissociates into sodium and chloride ions, but there is no gas produced to create fizzing.
