Calcium carbonate is most likely to dissolve in water with which characteristics? A.low pressure and cold temperatures B. low ca
ivolga24 [154]

Answer:

lots of carbon dioxide and cold temperatures

Explanation:

<em>Calcium carbonate has low solubility at room temperature and the solubility increases as the temperature decreases. The solubility of calcium carbonate also increases in water with high level of carbon dioxide due to the formation of more soluble bicarbonate. </em>

<em>CaCO_3_{(s)} + CO_2_{(g)} + H_2O_{(l)} --> Ca(HCO_3)_2_{(aq)}</em>

<em>This is why carbon dioxide rich rainwater is able to erode limestone rocks, leading to the formation of caves, stalactites and other structures in the long run as a result of reversal of the process.</em>

How long does it normally take to process one 12-ounce beer from your system?
Darina [25.2K]

Once the alcohol goes into our system, an ounce of it is process for a period of one hour.

The first stop happens in the stomach where absorption through the gastric lining and bloodstream occurs. Stronger drinks are absorbed more quickly. The second stop happens in the brain where its function decreases/ is increasingly impaired as the BAC or blood alcohol content grows. The third stop will be in the heart. However, it should be noted that it does not receive any physical alcohol, but its effects on the heart are strong. Alcohol is a vasodilator which means it causes blood vessels to dilate. This indicates more blood flow through the body-- but lowers the overall blood pressure. The fourth stop will be in the kidneys where blood is filtered. The fifth stop will be in the bladder where it will excreted from the body. Lastly, the liver is where the rest of alcohol left in your system is broken down. This process is known as metabolizing. The chemical that remains after metabolization is acetaldehyde and the body gets rid it by further metabolizing it into carbon dioxide and water.

Therefore, an ounce of alcohol is processed in our body for 60 minutes or one hour.

Según la clasificación de ecosistemas, indica si los siguientes ejemplos de ecosistemas son correctos: Una piscina es un ecosist
Hatshy [7]

Answer and Explanation:

  • <em>Una piscina es un ecosistema acuático y seminatural: FALSO. </em>La piscina corresponde a un ecosistema acuático, siempre y cuando existan seres vivos habitando en ese medio e interactuando entre ellos y con los factores físicos como temperatura del agua, pH, etc. No corresponde a un medio seminatural porque su origen es totalmente artificial, es decir, hecho por el hombre.
  • <em>La pradera es un ecosistema terrestre y natural : VERDADERO. </em>Es terrestre por encontrarse en un espacio continental no inundable, y natural por no ser intervenido por el hombre.
  • <em>Un bosque nativo es un ecosistema terrestre y natural: VERDADERO. </em>Un bosque no es inundable, por lo que se considera netamente terrestre y mientras no sea intervenido por la acción humana es un ecosistema natural.<em> </em>
  • <em>Un arroyo es un ecosistema dulceacuícola y natural: VERDADERO. </em>Entre las posibles ubicaciones de un ecosistema acuático, se hayan aquellos que se encuentran en un medio de agua dulce, tales como arroyos, lagos, ríos, entre otros. Al no ser alterado por el hombre, se lo considera también un ecosistema de origen natural.    <em> </em>
  • <em>El mar es un ecosistema marino y artificial: FALSO. </em>El mar sí es un ecosistema acuático marino. Sin embargo no es un ecosistema alterado o creado por el hombre en forma artificial, sino que tiene un origen plenamente natural.
  • <em>Las ciudades son ecosistemas terrestres y seminatural: FALSO. </em>Pueden ser consideradas terrestres por estar ubicadas en el continente, pero son de origen artificial por ser creadas por el hombre.
  • <em>Las represas son ecositemas seminatural y acuático: VERDADERO. </em>Las represas son creadas en un medio natural que ha sido parcialmente modificado por el hombre, lo que las convierte en seminaturales. Corresponden a ecosistemas acuáticos de agua dulce.

Which of the following accurately best describes the Ph scale?
lina2011 [118]
The Ph scale measures the acidity or alkalinity of water soluble substances (pHstands for 'potential of Hydrogen'). A pH value is a number from 1 to 14, with 7 as the middle (neutral) point. Values below 7 indicate acidity which increases as the number decreases, 1 being the most acidic.
