What is the MOLAR heat of combustion of methane(CH4) if 64.00g of
methane are burned to heat 75.0 ml of water from 25.00°C to 95.00°C?
(Water heat capacity-4.184 J/g°C)
5492 J/mol
21970 J/mol
343.0 J/mol
O
1373 J/mol

The answer is c fish

Hbr dissociates to form h+ and br-ca(oh)2 dissociates to form ca2+ and 2oh-the h+ and oh- react to form waterassuming the reactants are dissolved in water, the net reaction is h+ + oh- —> h2oif you’re asked to show all components of the reaction, the complete reaction is 2hbr + ca(oh)2 —> cabr2 + 2h2o

Depends on the speed of the car.

Ibelieve the answer is b.2200 watts, because p=vi; p=220(10); then p=2200hope my answer has you : )
