Answer:
5250 grams or 5.25 kg of carbon monoxide and 375 grams of hydrogen are required to form 6 kg of methanol.
Explanation:
The balanced reaction:
CO (g) + 2 H₂ (g) -> CH₃OH (l)
By stoichiometry of the reaction, the following amounts of moles of each compound participate in the reaction:
- CO: 1 mole
- H₂: 2 moles
- CH₃OH: 1 mole
Being the molar mass of each compound:
- CO: 28 g/mole
- H₂: 1 g/mole
- CH₃OH: 32 g/mole
By reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
- CO: 1 mole* 28 g/mole= 28 grams
- H₂: 2 moles* 1 g/mole= 2 grams
- CH₃OH: 1 mole* 32 g/mole= 32 grams
Being 6 kg equivalent to 6000 grams (1 kg= 1000 grams), you can apply the following rules of three:
- If by stoichiometry 32 grams of methanol are formed from 28 grams of carbon monoxide, 6000 grams of methanol are formed from how much mass of carbon monoxide?
mass of carbon monoxide= 5250 grams= 5.25 kg
If by stoichiometry 32 grams of methanol are formed from 2 grams of hydrogen, 6000 grams of methanol are formed from how much mass of hydrogen?
mass of hydrogen= 375 grams
<u><em>5250 grams or 5.25 kg of carbon monoxide and 375 grams of hydrogen are required to form 6 kg of methanol. </em></u>
Nuclear fusion is the source of all energy the Sun releases into space. The Sun fuses hydrogen at a steady rate, thanks to a natural feedback process that acts as a thermostat for the Sun's interior (p-p chain). Solar energy production remains steady because the rate of nuclear fusion is very sensitive to temperature.
<h3>Nuclear fusion</h3>
When two or more atomic nuclei join, one or more new atomic nuclei and subatomic particles are created. This reaction is known as nuclear fusion (neutrons or protons). Energy is released or absorbed depending on how much mass the reactants and products have in common.
The atomic nuclei before and after the reaction had different nuclear binding energies, which is how this difference in mass developed. Active or main sequence stars, along with other high-magnitude stars, are powered by nuclear fusion, which releases enormous amounts of energy. Energy will often be released during nuclear fusion that creates atomic nuclei lighter than iron-56 or nickel-62. Both their mass and nucleon binding energy are relatively high for these elements.

Answer:
3 × 10¯¹⁰
Explanation:
9×10² ÷ 3×10¹²
The above expression can be evaluated as follow:
9×10² ÷ 3×10¹²
Recall:
3² = 9
3¹ = 3
Therefore,
9×10² ÷ 3×10¹² = 3²×10² ÷ 3¹×10¹²
Recall:
y^m ÷ y^n = y^(m – n)
Therefore,
3²×10² ÷ 3×10¹² = 3²¯¹ × 10²¯¹²
= 3¹ × 10¯¹⁰
Recall:
y¹ = y
Therefore,
3¹ × 10¯¹⁰ = 3 × 10¯¹⁰
Therefore,
9×10² ÷ 3×10¹² = 3 × 10¯¹⁰
1.) produces tremendous amounts of energy with little fuel ( 4 lbs of H-2 and Li-6 produces the same energy as 9,000 T. of Coal )
2.) very abundant fuels Lithium ( for Tritium ) and Deuterium are found everywhere on the Earth Deuterium in water and Lithium in various sources
3.) fusion reactors require very special conditions so the reactions terminate with something goes wrong
