Answer:
Explanation:
Based on the scenario being described it seems that this is due to the later ionization energies, namely the 2nd, 3rd etc... seem to be much higher than the first. Therefore this causes an excess amount of energy to be used in order to remove the electrons, thus causing less energy to be left after the process is over. This would be the best explanation for this behavior.
It seems that you have missed the necessary options for us to answer this question, so I had to look for it. Anyway, here is the answer. Based on the ribbon diagram that represents a protein in water, it's <span>clear that the protein's quaternary structure is not present. Therefore, the answer is none of the above. Hope this helps.</span>
Answer:
False
Explanation:
Not all molecules are compounds, since some molecules, such as oxygen gas (above image of molecule of-O2) or ozone (O3), consist only of one element or type of atom. Water is also a molecule because it is made from atoms that have been chemically combined.
Answer:
2.24 M
Explanation:
Molality is a measure of molar concentration of a solution and it can be calculated using the formula;
Molality = mole of solute ÷ kg of solvent
To calculate the number of moles present in the solute, we use the formula;
mole = mass ÷ molar mass
Molar mass of Fe(ClO2)3 = 56 + {35.5 + 16(2)}3
= 56 + (35.5 + 32)3
= 56 + (67.5)3
= 56 + 202.5
= 258.5g/mol
mole = 435/258.5
mole of Fe(ClO2)3 = 1.68mol
750g of solvent = 750/1000 = 0.750kg of solvent
Molality of the solution is thus: 1.68/0.750
Molality = 2.24 M.
