2HgO = 2Hg + O₂
n(HgO)=2n(O₂)=2m(O₂)/M(O₂)
m(HgO)=n(HgO)M(HgO)=2m(O₂)M(HgO)/M(O₂)
m(HgO)=2*250.0*216.59/32.00 = 3384.219 g ≈ 3 kg 384 g
Answer:
coral bleaching is when the temperature of the water changes (even slight changes in temperature effect coral) and the coral reacts negatively to it causing it to die. unfortunately corals cannot recover once they have been bleached.
The answer is c. 104 g because 152-64 equals 88 and 192-88 equals 105
Answer:decreases
Explanation:don’t ask questions
The correct answer is option 1. It should be noted that a catalyst does not lower or decrease the activation energy because instead it provides an alternative route for the reaction to proceed. This speeds up a chemical reaction without being changed.
