Answer:

The correct answer is option E.

Explanation:

Reducing agents are defined as the agents which reduces the other substance and itself gets oxidized. These agents undergoes reduction reactions

Reduction reaction is defined as the reaction in which an atom gains electrons. Here, the oxidation state of the atom decreases or lowers.

X^{n+}+ne^-\rightarrow X

Oxidizing agents are defined as the agents which oxidize other substance and itself gets reduced. These agents undergoes reduction reactions.

Oxidation reaction is defined as the reaction in which an atom looses its electrons. Here, oxidation state of the atom increases or highers.

X\rightarrow X^{n+}+ne^-

aleksandr82 [10.1K]

Answer:

a). The products are C6H12O6 O2 and the reactants are CO2 + H20 + (solar (light) energy)

b). The reaction chemical reaction is balanced from the number of moles of reactants and products

Explanation:

Through photosynthesis green plants, some protistans and some bacteria in the presence of energy from sunlight, produce glucose as well as oxygen from carbon dioxide and water.

It is a chemical reaction taking place in green plant to produce food which it uses to survive.

Photosynthesis requires carbon dioxide, water and solar energy in the leaves of a plant for it to take place.

The equation for photosynthesis is as follows: 6CO2 + 6H20 + (solar (light) energy) → C6H12O6 + 6O2

The products are C6H12O6 O2

and the reactants are CO2 + H20 + (solar (light) energy)

The reaction chemical reaction is balanced from the number of moles of reactants and products

a scientist is measuring the measuring the temperature change in a chemical compound. the temperature dropped 11 per hr from the
stepladder [879]

Answer:

\large \boxed{134 \, ^{\circ}\text{C}}

Explanation:

1. Calculate the temperature drop

\text{Temperature drop} = \text{4 h} \times \dfrac{11 \,^{\circ}\text{C}}{\text{1 h}} = 44 \,^{\circ}\text{C}

2. Calculate the original temperature

\begin{array}{rcl}\text{Final Temperature} & = & \text{original temperature - temperature drop}\\90 ^{\circ}\text{C} & = & \text{original temperature - 44} \, ^{\circ}\text{C}\\\text{Original temperature}& = & \mathbf{134 \, ^{\circ}}\textbf{C}\\\end{array}\\\text{The original temperature was $\large \boxed{\mathbf{134 \, ^{\circ}}\textbf{C}}$}
