From what i understood from the question,the answer is organ
Answer:
The symbol which represents atomic structure is called atomic symbol. An electron is a negatively charged particle. Proton is a positively charged particle, located at the center of the atom. Neutron is an ellectrically neutral or charge less particle located in the nucleus of the atom.
Carbon is 6, and Magnesium is 12.
Hint: A mole is the entity that denotes 6.022×1023 particles.
Answer:
-The stronger electrostatic forces of attraction between the oppositely charged ions causes the Sodium chloride to break apart until it completely dissolves in the water.
Explanation:
-Sodium Chloride has positively charged sodium ions, and negatively charged chloride ions, .
-Water on the other hand has positively charged Hydrogen ions, and negatively charged Oxygen ions, due to the difference in electroneganivity.
-When dissolved in water, the positively charged sodium ions will attract the partially negatively charged oxygen ions. The negatively charged chloride ions will be attracted to the positively charged hydrogen ions in the reaction as below:
Un paciente que recibe suero fisiológico a una velocidad de infusión de 1 gota = 0,05 ml por segundo recibirá en 5 horas 790 grs de NaCl, tomando en cuenta que la solución acuosa de suero fisiológico contiene 0,878 grs/mL de NaCl.
Explicación
Los datos que se tienen son:
- Concentración de NaCl 0,878 grs/ml
- Volumen de la gota: 0,05 ml/gota
- Velocidad de infusión 1 gota/ seg = 60 gotas/ min = 3 ml/min
- Tiempo de infusión = 5 horas = 300 minutos
Ya establecidas las respectivas conversiones se trata de determinar qué volumen de suero fisiológivo se ha infundido al paciente en 5 horas
Si se infunden 3 ml cada minuto, ¿Cuánto se habrá infundido en 300 minutos?
3 ml ______________ 1 min
X ________________ 300 min
X = (300 min x 3 ml) / 1 min
X = 900 ml
Como en 5 horas el paciente ha recibido 900 ml de suero, se determina la cantidad de NaCl que se encuentra en ese volumen de líquido
0,878 grs __________ 1 ml
X ________________ 900 ml
X = (900 ml x 0,878 grs) / 1 ml
X = 790 grs de NaCl
