Answer:
Number of moles: 0.07407407407
0.60759572 gal is the volume of acid in gallons in a sample of hydraulic acid .
<h3>What do mean by the term "gallons" ?</h3>
The gallon is a unit of measurement for volume and fluid capacity in both the US units and the British imperial systems of measurement.
In SI base units, 1 Gal is equal to 0.01 m/s²
Since ,
1 L, l = 0.2641720524 gal
now, volume of acid in gallons is given by -
2.3 L, l = 2.3 × 0.2641720524 gal
=0.60759572 gal
Hence , 0.60759572 gal is the volume of acid in gallons in a sample of hydraulic acid .

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
<span>That would be compound!
Compounds are pure substances, which consists of two or more elements chemically combined in a fixed proportion by mass. Compounds have definite proportion.</span>
