Svetllana [295]

Answer:

773.43 torr

Explanation:

From the question given above, the following data were obtained:

Pressure (in inHg) = 30.45 inHg

Pressure (in torr) =?

We can convert 30.45 inHg to torr by doing the following:

1 inHg = 25.4 torr

Therefore,

30.45 inHg = 30.45 inHg × 25.4 torr / 1 inHg

30.45 inhg = 773.43 torr

Thus, 30.45 inhg is equivalent to 773.43 torr

Cuando el oxígeno reacciona con el calcio produce un sólido blanco muy utilizado en la preparación de cementos. ¿Cuál de las sig
8_murik_8 [283]

Answer:

2Ca + O₂ → 2CaO

Explanation:

Cuando el Calcio (Ca) reacciona con oxígeno (O₂) se produce cal (CaO). La cal es un sólido inodoro de color blanco a grisáceo. La cal es un óxido que se encuentra presente en el cemento y su cuantificación permite determinar la calidad y el tipo de cemento a utilizar.

La reacción que describe el proceso anterior es:

Ca + O₂ → CaO

Para balancear los oxígenos, se deben poner 2 CaO como producto:

Ca + O₂ → 2CaO

Para balancear los calcios, se pone como coeficiente del Ca un 2:

<h3>2Ca + O₂ → 2CaO</h3><h3 />

Esta última es la reacción que describe el proceso anterior

When inhaled, crystalline silica can cause scar tissue to form on what organs?
julsineya [31]

Crystalline silica is hazardous when small particles are inhaled. They can penetrate deep into the lungs and cause disabling and sometimes fatal lung diseases including silicosis, lung cancer and kidney disease. The particles of crystalline silica enters the lungs and causes the formation of scar tissue known as silicosis, thus reducing the lungs’ ability to take in oxygen.
