Which advantage of subdividing science into different areas ?

1 answer:

7 0

Answer:a successful classification or division implies the presence of the object own of each science and its relations with other related areas, the method or requirement of each science to face its object, and also its purpose for which poduce the fact of investigation.

Explanation:

Science is divided into numerous areas, each of which has as its object only a part of all the knowledge acquired, through experience and research.

The primary objective of science, is to improve the quality of life of humans, also helps solve everyday questions.

Science can be subdivided according to its object, its method, others by its affinity, complexity and dependence, however all classification tends to seek the links or relationships between the different disciplines or forms of knowledge, thus a successful classification or division implies the presence of the object own of each science and its relations with other related areas, the method or requirement of each science to face its object, and also its purpose for which poduce the fact of investigation.

A sample of 3.62 moles of diphosphorous trioxide is

Sindrei [870]

$H_3PO_3$ $2H_3PO_3$ $2H_3PO_3$ $P_2O_3$ Answer:

Explanation:

This question is about stoichiometry. From the balanced equation $P_2O_3 + 3H_2O$ ⇒ $2H_3PO_3$ , we see that 3 moles of water is needed to react with 1 mole of $P_2O_3$ .

This means that, to fully react 3.62 moles of $P_2O_3$ , we would need 3*3.62 or 10.86 moles of water. However, we only have 6.31 moles, so water is the limiting reactant.

Since 3 moles of water react with 1 mole of $P_2O_3$ , 6.31 moles of water can fully react with 6.31÷3 or 2.1033 moles of $P_2O_3$ .

From the balanced equation, we see that every mole of $P_2O_3$ reacted gets you 2 moles of $2H_3PO_3$ . Therefore, 2.1033 moles of $P_2O_3$ would give you approximately 4.21 moles of $H_3PO_3$ .

A binding protein binds to a ligand l with a kd of 400 nm what is the concentration of ligand when y is 0.25

vampirchik [111]

Answer:

The answer is 7600 nm.

Explanation:

As, Y = 0.25 = [ L ÷ (400 + (L)]

0.95 x 400 + 0.25 [ L] = [ L ]

380.25 = [ L ] - 0.95 [ L ]

= 0.05 [L]

[L] = 380 ÷ 0.05 = 7600nm
