Sediment is created by wind and water.
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
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
Answers:
2. valence electrons
3. a bond formed when atoms share one or more pairs of electrons.
4. chemical formula
5. a. calcium - 2
b. carbon - 4
c. sulfur - 6
6. a. electrons
7. the elements that make up water can't be split into a simpler form, but water can. water is a liquid at room temperature, oxygen and hydrogen are gases at room temperature.
8. because it is made of oxygen and hydrogen and one is partially negative and one is partially positive.
explanation: you’re welcome.
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.
