2) generating power by using fossil fuels is harvesting a non-renewable resource. The more you harvest = the less you have
Answer : The final volume of gas will be, 26.3 mL
Explanation :
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,

where,
= initial pressure of gas = 0.974 atm
= final pressure of gas = 0.993 atm
= initial volume of gas = 27.5 mL
= final volume of gas = ?
= initial temperature of gas = 
= final temperature of gas = 
Now put all the given values in the above equation, we get:


Therefore, the final volume of gas will be, 26.3 mL
Nuclear fusion in the sun involves hydrogen (H) atoms
combining to form helium (He). A student claims that since the atmosphere
contains hydrogen, any fusion reaction on Earth would result in an uncontrolled
chain reaction. What is wrong in the student’s reasoning is that the uncontrolled
chain reactions can only happen during nuclear fission.
The monomers that react together to form polyurethane polymer are diisocyanate and diol.
<h3>
What are polymers?</h3>
- Polymers are a class of natural or synthetic substances
- It is made up of small units called monomers arranged in a repeated pattern to form large molecules called macromolecules
- Cellulose and resins are examples of natural polymers
- Polyethylene and polychloroprene are examples of synthetic polymers.
Polyurethane polymer is made up of monomers diisocyanate and diol. It is mostly used in home furnishing in flexible form. The structures of monomers are as follows:
