Reactants on left (see on the arrow), products on right.
Final answer:
For the given chemical equation illustrating cellular respiration, the reactants comprise glucose (C6H12O6) and oxygen (6O2), and the products are carbon dioxide (6CO2) and water (6H2O). This symbolizes how in living cells, glucose and oxygen are transformed into energy, leading to the release of carbon dioxide and water as byproducts.
Explanation:
In the given chemical equation for cellular respiration, C6H12O6 (glucose) and 6O2 (oxygen) are the reactants and 6CO2 (carbon dioxide) and 6H2O (water) are the products.
This represents the process in living cells where glucose and oxygen are transformed into energy, releasing carbon dioxide and water as byproducts. Therefore, the correct answer is option A: Reactants are C6H12O6 + 6O2 and products are 6CO2 + 6H2O.

is the energy needed to raise an electron in the hydrogen atom from the second energy level to the third energy level.
What are Energy Levels?
The electrons that surround an atom around the nucleus are located in regions called "energy levels". It represents the 3-D space that surrounds the nucleus where the electrons are present. It is divided into several energy levels such as first energy level, second energy level and so on.
The level that is closest to the nucleus is the first energy level, then the second one is further away from it, then the third one is a little further away and so on. Each energy level has different number of electrons like first has 2 electrons, second has 8, third has 8 and so on. The electrons which are further away from the nucleus are called valence electrons.
For given above information,
E = - /
where,
= 13.6 eV (1 eV = 1.602×10-19 Joules) and n = 1,2,3… and so on so that the ground state has energy
= -13.6 eV and the second energy level (the first excited state) has energy
= -13.6/4 eV = -3.4 eV.
So,
1eV = 1.602×J
Energy difference can be calculated by -13.6eV (-
)
= Final energy;
= Initial energy
1.88 eV is equals to x
So, x= 3.03*
Thus, is the energy needed to raise an electron in the hydrogen atom from the second energy level to the third energy level.

Answer:
An SN2 (substitution nucleophilic bimolecular) reaction
Explanation:
This is a type of organic reaction that involves a nucleophile attacking an electrophilic center, resulting in the displacement of a leaving group from that center. This type of reaction typically occurs at a saturated carbon atom, where the nucleophile displaces a leaving group attached to that carbon atom. The reaction is bimolecular because it involves the collision of two molecules, the nucleophile and the substrate.

The answer choice is B) It should actually double.
Considering it's been in the bank so long, it would have increased because of interest rates.
