Anna35 [415]

Answer;

= 64561.95 g/mole

Explanation;

mass of Fe in 100g = .346g

= .346 / 55.8452 moles

= 0.0061957 moles  

These represent 4 moles of Fe in the molecule so moles of hemaglobin

=  0.0061957/4  

= 0.0015489 moles  

these are in 100 g so mass of 1 mole = 100 / 0.0015489

= 64561.95 g / mole

molar mass of hemoglobin = 64561.95 g/mole

-Dominant- [34]

Answer:

D ) feedback

Explanation:

When we use an air conditioner, it get turn off when reaches its required temperature and when the house warm up the air conditioning unit turns on again, that is an example of feedback.

The given condition is an example of negative feedback because in negative feedback, any change in the input is opposed by generating an output. Here also,  warming up of house (change in one direction) allows the air conditioning unit turns  on and it gives cool air (opposing that change).

Hence, the correct option is "D".

I am Lyosha [343]

Answer:

Water- 9.982 grams

toluene-8.669 grams

chloroform - 14.832 grams

Explanation:

the units of density are listed as g/mL. So for every mL of substance you have, you will have that many grams.

Water- .9982g/mL * 10 mL

As you can see, the units of "mL" cancel each other out, leaving just the gram amount of water.
