What must happen before a chemical reaction can begin

- the activation energy must be exceeded

- the activation energy must be reached

-the concentrations of products and reactants must be equal

- the concentration of reactant molecules must be reduced

Answers

Answer:

its B

Explanation:

The incident that happen before a chemical reaction can begin the activation energy must be reached. Thus, option B is correct.

What is activation energy?

The extra energy is the minimum amount of extra energy which required by reacting molecule to convert into the product.

Factor at which activation energy depends are as follows:-

1: Activation energy depends upon the nature of reactant if reactant is ionic then required activation energy is less and if reactant is covalent then required activation energy is high.

2: Nature of catalyst if catalyst is positive then required activation energy is less and if catalysts is negative then required energy is high.

3: Activation energy doesn't depend on pressure, temperature, volume etc.

Temperature is one the important factor at which any reaction is depend. In any reaction if temperature is increases the rate of reaction is increases and if temperature is decreases the rate of reaction is decreases.

Here, is the Arrhenius Equation  which shows the temperature dependence of the rate of a chemical reaction.

k=Ae^−EaRT

Where,

k= rate constant of the reaction

A= Arrhenius Constant

Ea= Activation Energy for the reaction (in Joules mol^-1)

R= Universal Gas Constant

T= Temperature in absolute scale (in kelvins)

Therefore, The incident that happen before a chemical reaction can begin the activation energy must be reached. Thus, option B is correct.

Scientists have developed a new herbicide for dandelions that is specifically designed to prevent the conversion of stored energy. Which process does this herbicide affect?

Answers

Answer:

Ability to make ATP or the release of oxygen from chloroplasts.

Explanation:

Given that, ATP which is an acronym for Adenosine triphosphate,  is where the energy is stored and produced in a plant and at the same time Herbicides affect plants in the area of photosynthesis specifically affecting the release of oxygen from chloroplasts, which in turn prevents the generation of energy required for plant growth.

Hence, in this case, the new herbicides affect the ability to make ATP in plants or the release of oxygen from chloroplasts.

. Distinguish between gross primary productivity and net primary productivity. Explain how net primary productivity affects the number of consumers in an ecosystem and on the earth. List two of the most productive ecosystems or aquatic life zones and two of the least productive ecosystems or aquatic life zones. Use the concept of net primary productivity to explain why harvesting plants from estuaries, clearing tropical forests to grow crops, and harvesting the primary producers in oceans to feed the human population are not good ideas.

Answers

Answer and Explanation:

The gross primary productivity corresponds to the sum of all the energy produced by the plants (primary producers) during the photosynthesis process. The net primary productivity, corresponds to the gross primary productivity value, even the energy value used by the plants in the metabolic processes that they present, in this way, we can conclude that the net primary productivity is the energy that is available for the living beings that consume the vegetias.

The ecosystems with the highest level of productivity are those that have a large number of vegetables with full access to the sun, in this case, we can mention forests and ecological parks. On the other hand, ecosystems with lower levels of productivity are those with a low number of plants, such as cities and areas with deforestation.

Because of our need to consume energy from net primary productivity, we are constantly harvesting vegetables and some photosynthetic water products to use in our food. However, this causes us to remove vegetables from nature and decrease the amount of gross primary productivity that ecosystems would have, and, consequently, decreasing the amount of net primary productivity that we need so much.
