Find My iPhone - Erase iPhone?

Am I correct in thinking that if I log in to iCloud and use the Erase iPhone feature for my phone, it will turn remove the passcode, and deactivate Find My iPhone?

Thanks.

Added (1). Basically the phone doesn't turn on and I need to deactivate the passcode and deactivate Find My iPhone. I'm concerned that if I erase all data, Find My iPhone will still be active but the device will longer be linked to my iCloud in order to turn off Find My iPhone. I'm also concerned that if I turn off Find My iPhone first, I won't be able to factory restore the device in order to deactivate the passcode.

How to calculate the overhead rate and overhead cost allocated of this problem?

Apple produces the iPhone 6 and the iPhone 5 iPhone 6 costs more to produce

a) calculate overhead rate of activity pools

Activity Pools costs for each pool are as follows - with cost drivers
i. $52,000 - # units produced
ii. 84,000 - # programming hours
iii. 6,000 - # of inspections
Total Overhead cost: $142,000

For iphone 6
# of units produced = 16,000
# of programming hours = 2,000
# of inspections = 190

For iphone 5
# of units produced = 36,000
# of programming hours = 1,500
# of inspections = 60

total of activity units
# of units produced = 52,000
# of programming hours = 3,500
# of inspections = 250

AFTER THAT: what is the overhead cost allocated of EACH PRODUCT (iPhone 5 and 6)

Added (1). ACCOUNTING

What minerals have the most bacteria in them?

For a school project I'm doing "Why the minerals in the iPhone matter". My main topic is how they trap bacteria the most and can cause acne breakouts in your skin. I know what minerals are in the iPhone but I don't know which ones are the most germy. Can someone tell me in general what minerals trap the most bacteria? Also here are the minerals in the iPhone (that we're using) so you can tell me if any of them trap bacteria the most.
