Explanation:
A catalyst lowers the activation energy of a reaction allowing them to proceed faster than they would naturally. Activation energy is the free energy that is required to be input in the reactant side to activate them to the transition state after which the reaction proceeds spontaneously to products.
An example of a catalyst is platinum, that is put in the exhaust of cars, to help convert carbon monoxide to carbon dioxide before it is emitted into the air.
Answer: they lower these activation required for the reactions to take place.
Explanation:
Step 2: Cl(g)+CHCl3(g)→HCl(g)+CCl3(g)(slow)
Step 3: Cl(g)+CCl3(g)→CCl4(fast)
What is the overall rate constant?
Methane (CH4) consists of a central carbon atom surrounded by four hydrogen atoms in the shape of a tetrahedron, due to the phenomenon of sp³ hybridization.
A molecule of methane, CH4, is composed of a single carbon atom surrounded by four hydrogen atoms. These atoms are placed at the corners of a geometric shape known as a tetrahedron. The carbon atom in methane exhibits a phenomenon called sp³ hybridization. Hybridization refers to the mixing of atomic orbitals to form new, hybrid orbitals. In the case of methane, this leads to four sp³ hybridized orbitals. When methane forms, each of these hybrid orbitals overlaps with a hydrogen orbital, thereby forming a C-H bond. This also creates four regions of electron density. The resulting molecular structure, a tetrahedron, has each of the four hydrogen atoms spaced 109.5° apart.

B:gravel on the bottom of the aquarium
C:temperature of the water
D:amount of oxygen in the water
To solve this we must be knowing each and every concept related to ecosystem. Therefore, the correct option is option A that is algae growing on the glass.
An ecosystem is created by how all living things interact with one another, with the chemical and physical components of their surroundings, and with each other through the movement of energy.
It includes every living item in a certain location along with their nonliving surroundings including air, water, and sunshine. Ecosystems provide for the basic necessities of humans. By supplying us with fresh food and clean water, ecosystems keep us alive.
They supply the basic ingredients we need to meet our demands for food, water, housing, clothes, and transportation. Algae growing on the glass is a biotic factor of an aquarium ecosystem.
Therefore, the correct option is option A.
