Answer:
Limited
Explanation:
Once it is used once, it is not reusable. Also, there's a possibility to use ALL the coal there is. That's why it's an unrenewable source, unlike the sun, wind, or water that never ends. Those are renewable
Answer:
Thermal energy transfers occur in three ways: through conduction, convection, and radiation. When thermal energy is transferred between neighboring molecules that are in contact with one another, this is called conduction.
The number of grams of Cl2 formed when 0.115 moles of HCl react with O2 is calculated as follows
write the chemical equation
4HCl + O2 -----> 2H2O + 2Cl2
if 0.115 moles of HCl reacted and from the equation above the reacting ratio between HCl and Cl2 is 4:2 therefore the moles of Cl2= 0.115 x2/4=0.0575moles
mass of Cl2= moles x molar mass of Cl2(35.5 x2=71g/mol)
=0.0575 moles x71g/mol = 4.0825 grams
