- If 4 moles of C8H18 are available to completely react with enough O2, how many moles of CO2 can be produced?

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.

: )

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
