Realiza la configuracion electronica,la CEE,grupo y periodo,de cada elemento,la estructura de lewis y la formula de sarrollada d
lesya692 [45]

Answer:

1s2 2s2 2p4

Explicación:

1s2 2s2 2p4 es la configuración electrónica de la molécula de agua. En el agua, hay 10 electrones, dos de hidrógeno y ocho de oxígeno. La subcapa 2s contiene un máximo de 2 electrones, mientras que la capa 2p puede acomodar seis electrones. El átomo de hidrógeno pertenece al primer grupo y el átomo de oxígeno pertenece al sexto grupo de la tabla periódica. En la estructura de Lewis, un átomo de oxígeno está unido a dos átomos de hidrógeno en un ángulo de 104,45 grados. Existe un enlace covalente presente entre el hidrógeno y el átomo de oxígeno en el que ambos se vuelven estables. El oxígeno necesita dos electrones, por lo que forma enlaces con dos átomos de hidrógeno que tienen un electrón cada uno.

What type of nosocomial infection is likely to arise from intravenous catheterization?
mrs_skeptik [129]

Answer:

The correct answer is c. Bacteremia

Explanation:

Nosocomial infection is a hospital-acquired infection. Intravenous catheterization is majorly used in hospitals for therapeutic purposes like drug administration, blood sampling, etc.  

These catheters are one of the major causes of nosocomial bacteremia in patients. Bacteremia is the condition in which bacteria is present in the blood.

So these catheter can be contaminated with bacteria which came from a patient and when they are used in another patient without proper sterilization they can transfer these bacteria to other patients blood which then cause nosocomial bacteremia.

What is the role of the protein pumps?
levacccp [35]

Answer:

Pumps, also called transporters, are transmembrane proteins that actively move ions and/or solutes against a concentration or electrochemical gradient across biological membranes. One moves with the concentration gradient (high to low) which powers the movement of the other against the gradient (low to high).
