Answer:
According to the Environmental Paper Network's Paper Calculator, it takes about 32 million BTUs of energy to produce 1 ton of virgin paper fiber. To produce 1 ton of recycled paper, it takes about 22 million BTUs.
so the answer could be it takes less Btu to manufacture recycled products than new ones
<h2>Gas Molecules Move in Random Motion </h2>
Explanation:
- According to the property of an ideal gas the volume occupied by the gas molecules themselves is negligible as compared to the volume occupied by the gas
- The molecules of ideal gas obey Newton's laws of motion thus they move in random motion
- According to the above statements we can conclude that Helium gas can fill many more balloons as compared to fit the baloons inside the cylinder because the particles of gas is free to move in random motion and can occupy more volume
Answer: To answer your question of what is true of a lewis base, it is true that a lewis base donates electron pairs.
Explanation: A Lewis base is any substance, such as the OH- ion, that can donate a pair of nonbonding electrons. A Lewis base is therefore an electron-pair donor.
<span> We are given with the rate constant of a first-order decomposition of n2o which is equal to 3.40 s-1. Half life of the radioactive material can be determined through the formula: t= ln2 /k where t is the half life of the material. t then upon substitution is equal to 0.2048 s. </span>
Answer:
Force of Tension = 1832.8 N
Explanation:
Any mass of object supported or pulled by a rope or cable is subject to a force of tension. Since the mass is raised by a cable, tension is involved.
Mathematically,
Tension = mass × gravity(9.8 m/s²)
Tension can be represented as
T = (m × g) + (m × a)
Where g is the acceleration due to gravity of the object the cable is supporting and a is the acceleration on the object the cable is supporting. And m is the mass of the object.
mass = 158 kg
a = 1.8 m/s²
g = 9.8 m/s²
T = mg + ma
T = m(g + a)
T = 158(9.8 + 1.8)
T = 158 × 11.6
T = 1832.8 N
