Answer:
B. Respiration
Explanation:
cellular respiration is the process where cells use glucose (C6H12O6) and oxygen gas (O2) to make carbon dioxide (CO2) water (H2O) and ATP, which is energy
formula:
C6H12O6 + 6O2 -> 6CO2 + 6H20 + 38ATP
Answer: 3.52 grams
Explanation:

Given moles:
moles of oxygen = 6.62
moles of 
According to stoichiometry:
2 moles of benzene reacts with = 15 moles of oxygen
Thus 0.08 moles of benzene will react with =
moles of oxygen
Thus benzene is the limiting reagent as it limits the formation of products and oxygen is the excess reagent.
As 2 moles of benzene produce = 12 moles of carbon dioxide
0.08 mole of benzene will produce =
of carbon dioxide
Mass of carbon dioxide=
Thus 3.52 g of carbon dioxide are produced.
Answer:
The table refers to emissions of CO2 from burning oil, coal and gas for energy use. Carbon dioxide also enters the Atmosphere from burning wood and waste materials and from some industrial processes such as cement production.
Explanation:
A chemical reaction occurs only when the collision between the reacting molecules takes place. However, not all the collisions are efficient in making the reaction. The products are produced only when the molecules colliding exhibits a certain kind of minimum energy known as threshold energy.
The threshold energy refers to the least amount of energy needed for the reactants to collide effectively, and to produce the activated complex. It is kinetic energy in supplementation with the energy of activation. Hence, threshold energy is more in comparison to the activation energy.
You must add 45 mL of the 80 % alcohol to the 30 % alcohol to get a 35 % solution.
You can use a modified dilution formula to calculate the volume of 80 % alcohol
V1×C1 + V2×C2 = V3×C3
Let the volume of 80 % mixture 1 = <em>x</em> mL. Then the volume of the final 35 % mixture 3 = (405 + <em>x</em> ) mL
(<em>x</em> mL×80 % alc) + (405 mL×30 % alc) = (405 + <em>x</em>)mL × 35 % alc
80x + 12 150 = 14 175 + 35 x
45x = 2025
x = 2025/45 = 45
