sorry i dont know 37 AND 38. :(
Explanation:
Answer:
2:2:1
Explanation:
The reaction expression is given as:
HXO → HX + O₂
We are to balanced this unbalanced reaction expression.
To solve this put, coefficient a, b and c before every specie:
aHXO → bHX + cO₂
Now use a mathematical approach to solve this;
Conserving H: a = b
X: a = b
O: a = 2c
let a = 1, b = 1 and c =
Multiply through by 2;
a = 2, b = 2 and c = 1
So;
2HXO → 2HX + O₂
Balanced ratio; 2:2:1

Answer:
The answer to your question is letter E. 288.4 g/mol
Explanation:
Data
Number of carbons = 19
mass percent of carbon = 79.12
molar mass = ?
Process
1.- Calculate the molar mass of 19 atoms of carbon
Atomic mass of carbon = 12 g
Atomic mass of 19 atoms of carbon = 228 g
2.- Use proportions to calculate the mass of testosterone
228 g --------------- 79.12 %
x -------------- 100 %
x = (228 x 100) / 79.12
Simplify
x = 22800 / 79.12
Molar mass of testosterone = 288.2 g
