1 answer:

Tema [17]3 years ago

7 0

Answer:

When air is admitted into the well, the water recedes from the level of static head to the bottom of the discharge pipe. The displaced column of liquid rises up the discharge pipe. Air bubbles mix with water and this reduces the specific gravity of the column of water sufficiently to lift it to the surface.

An iron chloride compound contains 55.85 grams of iron and 106.5 grams of chlorine. What is the most likely empirical formula fo

mart [117]

Answer:

$FeCl_{3}$

Explanation:

$Moles =\frac {Given\ mass}{Molar\ mass}$

mass of Fe = 55.85 g

Molar mass of Fe = 55.85 g/mol

<u>Moles of Fe = 55.85 / 55.85 = 1</u>

mass of Cl = 106.5 g

Molar mass of Cl = 35.5 g/mol

Moles of Cl = 106.5 / 35.5 = 3

Taking the simplest ratio for Fe and Cl as:

1 : 3

The empirical formula is = $FeCl_{3}$

vredina [299]

Answer:

<h2>6.14 cm³</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

$volume = \frac{mass}{density} \\$

From the question we have

$volume = \frac{55}{8.96} \\ = 6.138392...$

We have the final answer as

<h3>6.14 cm³</h3>
