Which of the following is a combustion reaction?
a. c3h8 (g) + 5o2 (g) → 3co2 (g) + 4h2o (g)
b. 2so3 (g) → 2so2 (g) + o2 (g)
c. 2na (s) + cl2 (g) → 2nacl (s)
d. 2kclo3 (s) → 2kcl (s) + 3o3 (g)

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

In an experiment, how can i change human errors? be specific.

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 j 1: write the equation 2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!
