Answer:

Explanation:
Hello there!
In this case, since we have a problem about volume-pressure relationship, the idea here is to use the Boyle's law to calculate the final volume as shown below:

Then, we plug in the initial and final pressures and the initial volume to obtain:

The mathematical expression for mass percent is given by:

Put the values,

mass of zinc = 
=
or 65.4 g
Now, number of moles of zinc =
=
= 1.00 mole
Number of atoms of zinc is calculated by the Avogadro number.
Now, according to mole concept
molecules of enzyme consists of
atoms of zinc
So, 1 molecule of enzyme contains =
= 1 atom of zinc.
Hence, every carbonic anhydrase molecule consists of 1 atom of zinc.
Answer:
Which statements describe polyatomic ions? Check all that apply.
Polyatomic ions have many charges.
Polyatomic ions have one overall charge.
Polyatomic ions repel other ions to form ionic bonds.
Polyatomic ions attract other ions to form ionic bonds.
Polyatomic ions are made up of only one type of atom.
Polyatomic ions are made up of two or more types of atoms.Explanation:
Answer:742 torr= approximately 0.976 atm
Explanation:
Since we know that one atm= 760 torr, we can compute the following calculation:
(742 torr/1)*(1atm/760torr)=0.976316 atm
Remember sig figs (3) to round it to 0.976 atm
*
=0.976316=0.976 atm
(torr cancels out and we're left with atm)
Hope this helps :)
Idk I think its a major addation Or Reading Or Socail Studies Sorry tho
