A sample of hydraulic acid has a volume of 2.3L. What is the volume of acid in gallons?
Assoli18 [71]

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 .

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
