Answer:
according to me I think acid is answer
Explanation:
answer is acid
like it and follow me
Assume 1mol of Al2O3:
mm(Al) = 26.98g/mol
x2(moles needed in 1mol of Al2O3)
= 53.96g
~54g
mm(O) = 16.00g/mol
x3(moles needed in 1mol of Al2O3)
=48g
mm(Al2O3) = m(Al) + m(O)
= 102g/mol
x1mol
=102g (in 1 mol)
<em>What</em><em> </em><em>percent</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>total</em><em> </em><em>does</em><em> </em><em>X</em><em> </em><em>or</em><em> </em><em>Y</em><em> </em><em>take</em><em> </em><em>up</em><em>?</em>
Just take the portion that it gets and divide by the total:
Al: 54/102 = 53%
O: 48/102 = 47% or 100%-53%=47%
<em>Notice that, with binary compounds, you only need to calculate one of the two elements: the remaining amount HAS to be taken up by the other element, or else there would be something else involved.</em>
120 grams of NaOH means 3 Moles of NaOH because 40 grams (Molecular Weight in grams) is one mole of NaOH.
Each mole of any substance contain Avogadro’s number of molecules ie., 6.022 x (10 to the power 23).
Hence 3 Moles of NaOH contain 3 times of Avogadro’s number of molecules ie., 3 x 6.022 x (10 to the power 23)
An electron accelerates through a twelve.five V potential contrast, starting from rest, and then crash with a hydrogen atom, exciting the atom to the highest energy level grant. List all the probable quantum-jump progression by which the excited atom could emit a photon and the wavelength of each.
Answer:
Organic chemistry
Explanation:
Organic material like alcohols and esters are composed mostly of carbon structures, hence the branch is referred to as organic chemistry
