Answer:

neutrons, isotope

Explanation:

Isotopes are atoms of the same element with different atomic mass. The difference in atomic mass is as a result of difference in the number of neutrons in the nuclei of the atoms.

Hence, changing the number of neutrons of an atom with result in having different atomic mass but the number of protons and electrons remain the same.

a 10.99g sample of NaBr contains 22.34% Na by mass. Considering the law of constant composition (define proportions), how many g
leonid [27]

Given :

A 10.99 g sample of NaBr contains 22.34% Na by mass.

To Find :

How many grams of sodium does a 9.77g sample of sodium bromine contain.

Solution :

By law of constant composition , in any given chemical compound, the elements always combine in the same proportion with each other.

Therefore , percentage of Na by mass in NaBr will be same for every amount .

Percentage of Na in 9.77 g NaBr is 22.34 % too .

Gram of Na = 9.77\times \dfrac{22.34}{100}=2.18\ g .

Hence , this is the required solution .

How many tons of zinc can be obtained from 976 tons of zinc ore that is 78.0% zinc carbonate?
kramer
First, calculating the amount of zinc carbonate by multiplying the given mass of the ore by the percent zinc carbonate. 
                          mass of zinc carbonate = (976 tons)(0.78) 
                                                       = 761.28 tons
Then, calculate for %Zn in zinc carbonate
                           %Zn = ((65.38) / (125.39)) x 100%
                                          % Zn = 52.141%
tons of Zn from the sample,
                           mass of Zn = (761.28 tons)(0.52141)
                                              = 396.94 tons Zn

Hemoglobin (Hb) can be viewed as having two quaternary states, a low oxygen affinity state (T), and a high oxygen affinity state
natta225 [31]
<h3><u>Answer;</u></h3>

The statements that are True are;

  • Upon binding a molecule of oxygen, Hb undergoes a conformational change that makes the binding of subsequent O2 molecules easier.
  • The conformational change induced in Hb upon binding oxygen is the result of a small movement (0.2 Å) of the iron cation in the center of heme.
  • Site-directed mutagenesis studies have indicated that the cooperativity of O2 binding in Hb is attributable to the movement of the F helix in Hb.
<h3><u>Explanation</u>;</h3>
  • Hemoglobin is a key pigment in the blood that transports oxygen gas to all the tissues in the body. It is made up of two types of chains; that is two alpha chains and two beta chains.  
  • in its deoxygenated state hemoglobin has a low affinity for oxygen compared to myoglobin. When oxygen is bound to the first subunit of hemoglobin it leads to subtle changes to the quaternary structure of the protein. This in turn makes it easier for a subsequent molecule of oxygen to bind to the next subunit.
