The pair of reactants that would produce hydrogen most slowly is one that has a high activation energy barrier to overcome in order for the reaction to proceed. For example, a reaction between a less reactive metal like copper and a weak acid like acetic acid would produce hydrogen slowly compared to a more reactive metal like magnesium and a strong acid like hydrochloric acid. This is because the less reactive metal and weak acid combination would have a slower reaction rate due to the higher activation energy required for the reaction to occur.
What else can I help you with?
Is H2O plus Mg a mixture?
No, H2O plus Mg does not form a mixture. Mixing water (H2O) with magnesium (Mg) would not result in a homogenous combination of substances. Instead, the magnesium would likely react with the water, producing magnesium hydroxide (Mg(OH)2) and hydrogen gas (H2).
What would adding sodium hydride to ethanol produce?
Adding sodium hydride to ethanol would produce sodium ethoxide and hydrogen gas. Sodium hydride is a strong base and will react with ethanol to form the ethoxide salt and release hydrogen gas as a byproduct.
How many moles of sodium will react with water to produce 4.0 mol of hydrogen in the reaction 2Na plus 2H2O---2NaOH plus H2?
Your equation is properly balanced so for every mole of hydrogen produced it takes 2moles of sodium; therefore to produce 4.0 mol of hydrogen it would take at least 8.0 mol of sodium if the reaction were 100 % efficient.
What would be the effect of the hydrogen on limewater?
Hydrogen gas does not directly react with limewater (calcium hydroxide solution) to produce a visible change. Limewater is typically used to test for the presence of carbon dioxide, which would cause the solution to turn milky due to the formation of insoluble calcium carbonate.
What is the theoretical yield of beryllium needed to produce 36.0 g of hyddrogen?
The molar ratio between beryllium and hydrogen in the reaction will determine the theoretical yield. You would need to know the balanced chemical equation for the reaction involving beryllium and hydrogen to determine the theoretical yield of beryllium.
What will happens when you soak a nail in a vinegar for 3 days?
the acetic acid in the vinegar would slowly dissolve the iron and produce hydrogen gas
What reactants would give sodium chloride plus hydrogen?
Sodium with HCl gives NaCl and H2 2Na + 2HCl -> 2NaCl + H2
When hydrogen and oxygen conforms to water what would water be considered and what would hydrogen and oxygen be considered?
Hydrogen and oxygen are the reactants and water is the product.
How much hydrogen would be required to produce 7.5 mol of water?
To produce 1 mol of water, 2 mol of hydrogen is needed. Therefore, to produce 7.5 mol of water, you would need 15 mol of hydrogen.
Is H2O plus Mg a mixture?
No, H2O plus Mg does not form a mixture. Mixing water (H2O) with magnesium (Mg) would not result in a homogenous combination of substances. Instead, the magnesium would likely react with the water, producing magnesium hydroxide (Mg(OH)2) and hydrogen gas (H2).
How much hydrogen would be required to produce 7.4 mol of water?
To produce 1 mole of water, you need 2 moles of hydrogen. Therefore, to produce 7.4 moles of water, you would need 2 * 7.4 = 14.8 moles of hydrogen.
What is a sentence with hydrogen?
Hydrogen is the simplest element in the universe. Combining hydrogen and oxygen in a fuel cell would produce energy without pollution.
If the reactants of a reaction are 2AgClO3 and Na2CO3 what is the product?
The reaction between 2AgClO3 and Na2CO3 would produce Ag2CO3 and NaClO3.
In order to create the product h20 what reactants are necessary?
you could burn hydrogen in air, where the oxygen in the air would combine with the hydrogen to form water vapor which could be condensed on a cold surface. Also, the general reaction Base + Acid gives Salt + water for example Hydrochloric acid reacting with Sodium hydroxide gives water plus sodium chloride. Many other reactions have water as a by-product.
What reactants would give zinc nitrate water?
Reacting zinc metal (Zn) with nitric acid (HNO3) would produce zinc nitrate (Zn(NO3)2) and hydrogen gas (H2). Water can be added to dissolve the zinc nitrate salt after it is produced.
How would you classify a chemical reaction between two reactants that produce one product?
This type of reaction is known as a synthesis reaction, where two reactants combine to form a single product.
What direction doe the equilibrium shift when reactants are added to it?
Adding reactants to an equilibrium mixture will cause the equilibrium to shift to the right in order to consume the excess reactants. This helps restore the equilibrium conditions by favoring the forward reaction to produce more products.
