describe how this apparatus can be used to investigate the effect of temperature on the rate of decomposition of hydrogen peroxide

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
