The formation of compound takes place by the combination of two or more different atoms. The combination of atoms takes place in a definite proportions. Compounds with different proportions of atoms have different properties.

Water (H_2O) is composed of the same element as hydrogen peroxide (H_2O_2) that is hydrogen (H) and oxygen (O). The combination of hydrogen and oxygen atoms in water is in 1:2 ratio whereas the combination of hydrogen and oxygen atoms in hydrogen peroxide is in 2:2 ratio. So, the properties of water and hydrogen peroxide are different as the arrangement of atoms is different in the compound.

Hence, the correct option is they have different properties because the arrangement of atoms is different.

The basic building blocks of a protein are
snow_lady [41]


The building  blocks of protein are amino acids.

Amino acids are a class of organic compounds that contain at least one amino group, -NH2, and carboxyl group, -COOH.

Alpha amino acids , RCH(NH2)COOH, are the building blocks  from which proteins are constructed.

The NH group of one amino acid and the COOH  group of the other amino acid are joined together and a peptide bond -CONH-  is formed between the two amino acids and the product is called a dipeptide.

A 1dm3 solution was made by mixing 0.0040 mol of HCl(aq) and 0.0025 mol of NaOH(aq). What was the pH of the resulting solution?
kicyunya [14]

The pH of the resulting solution is 2.82.

<h3>What is pH ?</h3>

pH is the measure of acidity and alkalinity of a solution , It has a range of 1 to 14.

HCl          +                   NaOH      →         NaCl       +         H₂O

0.0040                         .0025                 0                       0

0.0040 -0.0025             0                   0.0025          0.0025

Moles of HCl = 0.0015

As 0.0025 moles of NaOH reacts with 0.0025 moles of HCl leaving behind 0.0015 moles of HCl

Concentration of HCl = 0.0015/ 1 = 0.0015 M

[ H⁺] = 0.0015 M

pH = -log [ H⁺]

pH = -log [ 0.0015]

pH = 2.82

Therefore the pH of the resulting solution is 2.82.

What do we know about elements with half-filled energy levels??
lisabon 2012 [21]
If the energy level of a certain element is filled based on the maximum number of allowable electrons per level, then it is no longer reactive. With this, half-filled energy level means that the element may retain those electrons and attract electrons from other elements or it may give off its electrons.
