Answer:
See exaplanation
Explanation:
For this question, we several sub-questions, lets start with the first one:
<u>What is its molecular formula?</u>
<u />
For this question we have to multiply the subunit by the number of subunits in the polysaccharide, so:
<u>What is its molar mass?</u>
<u />
For this question, we have to find the molar mass of 1 subunit and then multiply by the number of subunits:
Atomic masses: C: 12 g/mol H: 1 g/mol O: 16 g/mol
Now we can multiply, the atomic masses by the number of atoms, so:
If we take into account the number of subunits:
<u>What is the empirical formula of amylose?</u>
<u />
In this case, we have to remember that the empirical formula is the smallest number of atoms. In other words, we have to simplify the formula. Therefore, the smallest formula is the subunit formula: .

You would get four moles of magnesium nitrate :) you would have to
“ ?molesmg(oh)2 = 8molmg(no3)2 x molmg(oh)2 / 2molhno3 = 4 moles of magnesium nitrate :))) hopefully this helps! <3
No, a theory is the answer
Explanation:
Orifice meters require to compensate for pressure and temperature when one uses these meters to measure the steam or the gas flow in the pipes with the variable operating pressure as well as temperature conditions.
Normally chemists do not have online density measurement tool and thus to avoid complications, the chemists consider density as constant parameter.
<u>In the steam or the gas flow measurement, density of steam or gas changes as the pressure and the temperature change. This significant change in the density can affect accuracy of measured flow rate if the change is uncompensated and thus, this has to be fixed in order to avoid errors.</u> Therefore, it is important to compensate for the pressure and the temperature when orifice is used to measure the steam or the gas flow.
This answer is based on the electron configuration.
And you can use Aufbau's rule to predict the atomic number of the next elements.
Radon, Rn is the element number 86.
Following Aufbau's rules, the electron configuration of Rn is: [Xe] 6s2 4f14 5d10 6p6. This means that you are suming 2 + 14 + 10 + 6 = 32 electrons with respect to the element Xe.
You can verity that the atomic number of Xe is 54, so when you add 32 you get 54 + 32 = 86, which is the atomic number of Rn.
Again, as per Aufbau's rules, the next element of the same group or period is when the 6 electrons of the 7p orbital are filled. For that, they have to pass 32 elements whose orbitals are:
7s2 5f14 6d10 7p6: count the electrons added: 2 + 14 + 10 + 6 = 32, and that is why the next element wil have atomic number 86 + 32 = 118.
Now, when you go for a new series, you find a new type of orbital, the g orbital, for which the model predict there are 18 electrons to fill.
So the next element of the group will have ; 2 + 18 + 14 + 10 + 6 = 50 electrons, which means that the atomic number of this, not yet discovered element, has atomic number 118 + 50 = 168.
By the way the element with atomic number 118 was already discovdered at its symbol is Og. You can search that information in internet.
Answers: 118 and 168
