the answer is 332.25 grams
Explanation:
The given chemical equation is:
Fe(CN)63-(aq) + Re(s)-> Fe(CN)64-(aq) + ReO4-(aq)
Consider oxidation half reaction and balance it first in acidic conditions:
Add water on the left side to balance the O-atoms:
Add protons on the right side to balance H-atoms:
To balance the charge add electrons:
------------(1)
Reduction half reaction:
Fe(CN)63-(aq) -> Fe(CN)64-(aq)
Add electrons to balance the charge:
---------------(2)
Multiply equation(2) with seven :
------(3)
Add (1) and (3)
Add 8OH- on both sides:
It becomes:
This is the final equation in the basic medium.
Re(s) is oxidised. So it is the reducing agent.
Fe(CN)63- is reduced.It is the oxidising agent.
Answer: The rate of the reaction decrease over time as the reaction proceeds, a decrease in the concentration of reactants results in fewer successful collisions.
Explanation:
Rate of a reaction is defined as the change in concentration of products and reactants with respect to time.
The rate of a reaction decreases with times because reactants are converting into products.
As a result, the reaction is proceeding with a decrease in the concentration of reactants due to which less number of collisions between the reactant molecules will be there.
Hence, rate of reaction will decrease.
Thus, we can conclude that the rate of the reaction decrease over time as the reaction proceeds, a decrease in the concentration of reactants results in fewer successful collisions.
Answer:
B: They are resources that are in abundant supply and can replenish themselves quickly.
Explanation:
A renewable resource is one that can be used repeatedly and does not run out because it is naturally replaced. Examples of renewable resources include solar, wind, hydro, geothermal, and biomass energy.
