Answer: It will be produced 276,3 mg of product
Explanation: The reaction of anthracene (C14H10) and maleic anhydride (C4H2O3) produce a compound named 9,10-dihydroanthracene-9,10-α,β-succinic anhydride (C18H12O3), as described below:
C14H10 + C4H2O3 → C18H12O3
The reaction is already balanced, which means to produce 1 mol of C18H12O3 is necessary 1 mol of anthracene and 1 mol of maleic anhydride.
1 mol of C14H10 equals 178,23 g. As it is used 180 mg of that reagent, we have 0,001 mol of anthracene. With it, the reaction produces 0,001 mol of C18H12O3.
As 1 mol of C18H12O3 equals 276,3 g, the mass produced is 276,3 mg.
Answer:
6
Explanation
every p sublevel holds up to 6 electrons
so the 4p sublevel must hold up to 6 electonsr
Answer:- The formula tells us that one formula unit of this compound is composed of one calcium atom, two nitrogen atoms, and six oxygen atoms.
Explanations:- Subscripts tell us about the number of atoms of the element for which they are used. For example, here the subscript of Ca is one, it means there is one calcium atom in the given one formula unit.
When we have subscripts inside and outside the parenthesis then they are multiplied and the outside subscript is considered for all the atoms present inside the parenthesis.
Here, for the given chemical formula, the subscript of N is 1 and the subscript present outside is 2. So, 1 x 2 = 2 and for oxygen, 3 x 2 = 6
So, we have one calcium atom, two nitrogen atoms and six oxygen atoms for one formula unit of given compound.
Answer:
The volume of the flask is<u> 20.245 litres .</u>
Explanation:
We are given with following information-
-------- 1
where R =
Molar mass of
The given chemical equation is -
--------- 2
Now , calculation -
Mass of formed = 118g
Molar mass of =
Mole =
Therefore , moles of formed =
From equation 2 , we get to know that ,
2mole formed from 5 mole
Therefore , mole formed from mole
Moles of used =
R=
Pressure (P)= 1.85atm
Temperature (T)= 322K
Moles of (n)= moles
Applying the formula above in 1 equation , that is
PV = nRT
putting the given values -
V = 20.245 litres.
Hence , the volume of the flask is <u>20.245 litres . </u>
