<h2>Let us derive empirical formula </h2>
Explanation:
We are given with compound C₆N₄O₁₀: mass percentage of all is :
For C = 12 x 6 /288=0.25%
For N= 14 x 4 /288=0.19%
For 0= 16 x 10/288=0.5%
The elements present are :
Atomic mass moles Simplest ratio rounding off
C 12 0.25/12=0.020 0.02/0.02=1 2
N 14 0.9/14=0.06 0.06/0.02=3 6
O 16 0.5/16=0.03 0.03/0.02=1.5 3
The empirical formula derived is : C₂n₆O₃
Answer:
Faster hydrogen burning means the star will grow larger and more luminous to allow the extra energy created to escape
Answer : The light rays are bent and refraction will occur - B.
Answer:
Neutralization reactions
Explanation:
A neutralization reaction is a reaction between an acid and a base. Products of this type of reaction is water and a salt. The pH of the salt product would depend on how strong or weak the base and acid would be when they react with each other. Although the characteristics of bases and acids are practically polar opposites, when combined, they cancel each other our producing a neutralized product.
