Answer: The reaction must proceed in the reverse direction.
Explanation:
is the constant of a certain reaction at equilibrium while is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.
For the given chemical reaction:
The expression of for above equation follows:
We are given:
There are 3 conditions:
When ; the reaction is product favored.
When ; the reaction is reactant favored.
When ; the reaction is in equilibrium.
As, , the reaction will be favoring reactant side or the reaction must proceed in the reverse direction.
Hence, the reaction must proceed in the reverse direction.
B. slow
C. variable
D. constant
Answer:
correct answer is option C (constant)
Explanation:
Radioactive decay of radioactive element occur at known rates, the unit of radioactive decay is called half-life. The amount of time a radioactive element takes for half of the parent atoms to decay is known as half-life of a radioactive element
During Radioactive decay radioactive elements emits a particle. It's impossible to predict exactly when a given atom of a substance will emit a particular particle, but the decay rate of a radioactive element over a long period of time is constant.
By radioactive decay scientist can determine the age of that particular element. If radioactive decay will vary than age cannot be determined from radioactive decay.

Explanation:
Answer:
Single-stream recycling has two main advantages: Since it's so much easier than sorting out recyclables for individuals, it increases household recycling rates, and since it's easier to dump one can of stuff into a collection truck with one compartment, it saves cities money.
Benefits of Recycling: Reduces the amount of waste sent to landfills and incinerators. Conserves natural resources such as timber, water and minerals. Increases economic security by tapping a domestic source of materials. Prevents pollution by reducing the need to collect new raw materials. Saves energy.
