\huge\mathsf{\red{\underline{\underline{Compound}}}}

{\green{\dashrightarrow}}A chemical compound is a chemical substance that is made of two or more atoms of different elements that share a chemical bond.

{\green{\dashrightarrow}}A chemical formula represents the ratio of atoms per element that make up the chemical compound.

\large{\pink{\sf{5~ Examples~ of~ Compound~ are:-}}}

<h3><u>Example 1</u><u> </u><u>:- </u></h3>

  • Water (H2O, consisting of 2 hydrogen atoms and one oxygen atom)

<h3 /><h3><u>Example 2 :- </u></h3>

  • Carbon dioxide (CO2, consisting of one carbon atom and two oxygen atoms)

<h3 /><h3><u>Example 3 :- </u></h3><h3 />
  • Sodium Chloride (NaCl, consisting of one sodium atom and one chloride atom)

<h3><u>Example</u><u> </u><u>4</u><u>:</u><u>-</u></h3>

  • Methane (CH4, consisting of one carbon atom and four hydrogen atoms)

<h3><u>Example</u><u> </u><u>5</u><u> </u><u>:</u><u>-</u></h3>

  • Pure glucose is a compound made from three elements - carbon, hydrogen, and oxygen. The ratio of hydrogen to carbon and oxygen in glucose is always 2:1:1.

¿Qué tipos de proteínas corresponden a la parte sólida del cuerpo y que porcentaje?
Nataly_w [17]

Answer:

The solid parts are the bones or the bone / cartilage tissue of the body, where they are composed of proteins such as: collagen type 1 approximately 80%, in addition 10% of other proteins combined with polysaccharides such as osteonectin and bone sialoprotein, or others proteinglucan or glycoproteins.

Explanation:

These proteins are proteins that make up the bone tissue structure, forming part of the extracellular matrix, providing consistency and support.

Type 1 collagen is one of the most important proteins in hard tissues, since it is one of the first to be formed by the osteoblast during osteoid formation, which will later calcify and conform to mature bone.

The synthesis of type 1 collagen fundamentally requires vitamin C, and it is also synthesized initially in a reticular way when the bone is immature, and then linearly when the bone becomes laminar or mature.

A solution of water (kb=0.512 ?c/m) and glucose boils at 103.06 ?c. what is the molal concentration of glucose in this solution?
nirvana33 [79]
<span>When a solute is added to a solvent, some properties are affected and these set of properties are called colligative properties. The properties depend on the amount of solute dissolved in a solvent. For this we use the boiling point elevation of the solution. We do as follows:

</span>ΔT(boiling point) = 103.06 °C - 100.0 °C= 3.06 °C<span>
ΔT(boiling point)  = (Kb)m
m = </span>ΔT(boiling point) / Kb<span>
m =  3.06 °C / 0.512 °C kg / mol
m = 5.98 mol / kg
