Xg of U and 3.795 g of O combine to form 20.00 g of
1 answer:
The percent composition of Uranium in U308 = C. 81.03%
<h3>Further explanation</h3>Given
X g of U
3.795 g of O
20.00 g of U308
Required
The percent composition of Uranium
Solution
mass of Uranium in U308 :
= mass of U308 - mass of O
= 20 g - 3.795 g
= 16.205 g
The percent composition :
%U = (mass U/mass U308) x 100%
%U= (16.205/20) x 100%
%U = 81.025≈81.03

Answer:
Here's what I get
Explanation:
1. Complete structural formula
Methylpropane consists of a chain of three carbons with another carbon atom attached to the middle carbon. Enough H atoms are added to give each C atom a total of four bonds.
The complete structural formula is shown below (There is a C atom at each intersection).
2. Condensed structural formula
A condensed structural formula is designed to be typed on one line.
The molecule has three CH₃ groups attached to a single carbon atom, so the condensed structural formula is
(CH₃)₃CH
The formula is also often written CH₃CH(CH₃)CH₃ and as (CH₃)₂CHCH₃.
