What is a chemical property of soda ash

1 answer:

8 0

A chemical sodium carbonate (Na2CO3), produced by reacting sodium chloride and limestone, is commonly known as soda ash.

Soda ash has a number of chemical properties and one of the important properties is that it a basic i.e. an alkaline compound. It can be used as a pH regulator for a number of processes such as raising the pH of a swimming pool.

It is also a good electrolyte and can make a good conductive solution when add to water.

What mass in kilograms of E85( d = 0.758 g/mL ) can be contained in a 13.0 gal tank?Express your answer to three significant fig

melamori03 [73]

The mass in kilograms of E85 with density of 0.758 g/mL that can be contained in a 13.0 gallon tank is 2,869.34g.

<h3>How to calculate mass?</h3>

The mass of a substance can be calculated using the following formula:

Density = mass ÷ volume

According to this question, a substance E85 has a density of 0.758g/mlL and it contains 13.0gallon of liquid. The mass can be calculated as follows:

13 gallon can be converted to 3785.412 millilitres

mass = 0.758 × 3785.412

mass = 2,869.34g

Therefore, the mass in kilograms of E85 with density of 0.758 g/mL that can be contained in a 13.0 gallon tank is 2,869.34g.

A constant current of 0.350 A is passed through an electrolytic cell containing molten CrCl₂ for 21.7 h. What mass of Cr(s) is p

zhuklara [117]

An electrochemical cell can generate or use electrical energy. The mass of solid chromium that will be deposited on the electrochemical plate is 7.17 gm.

<h3>What is current?</h3>

Current in an electrochemical cell is the ratio of the quantity of electricity in columns and time in seconds.

Given,

Current (I) = 0.350 A

Time = 21.7 hours

Molar mass of chromium = 52.0 g/mol

First time is converted into seconds:

1 hour = 3600 seconds

21.7 hours = 76020 seconds

The quantity of electricity flowing in the electrochemical solution is calculated as:

$\begin{aligned} \rm Q & = \rm It\\\\& = 0.350 \times 76020 \\\\& = 26607\;\rm C \end{aligned}$

Electricity required for depositing 1 mole or 52.0 g chromium is calculated as:

In electrochemical solution, chromium chloride is dissociated as:

$\rm CrCl_{2} \rightarrow Cr^{2+} + 2 Cl^{-} \\\\\rm Cr^{2+} +2 e^{-} \rightarrow Cr$

Two moles of electrons are needed to deposit 52.0 g of chromium.

If, 1 electron = 96500 C

Then, 2 electron = 193000 C

The mass of chromium deposited is calculated as:

193000 C = 52 g chromium

So, 26607 C = $\dfrac{26607 \times 52}{193000} = 7.17 \;\rm gm$

Therefore, 7.17 gm of chromium is produced.
