Which reaction below represents a balanced, single replacement chemical reaction?

kenny6666 [7]

The balanced chemcial equation is B. So to do single, we need to look at where would Li stand on the metals chart (For my class we have a chart to see which element is the highest on the metals chart) . So since Li is higher, F needs to go with Li, leaving Ba alone.

I hope this helps you!

In addition to reacting with gold (see Problem 21.21), aqua regia is used to bring other precious metals into solution. Balance

suter [353]

Aqua regia is used to bring precious metals into the solution .

$3Pt(s)+ 4NO^{-} _{3} (aq)+18 Cl^{-} (aq) +16H^{+} =3Pt Cl^{2-} _{6} (aq) +4NO(g) +8 H_{2} O$

This is the balanced reaction of Pt (platinum) .

<h3>What is aqua regia ?</h3>

It is a mixture of concentrated nitric acid and hydrochloric acid .there is three part of concentrated HCl and 1 part of concentrated nitric acid .

it is red or yellowish liquid . it is extremely corrosive and can cause skin burns . it is frequently used to dissolve gold and platinum .

The equation of reaction of aqua regia with gold :

$Au + 4H^{+} +NO^{-} _{3} +4Cl^{-} =AuCl^{-} _{4} +NO +2H_{2} O$

Which are the products in this chemical reaction? 2C4H10 + 13O2 8CO2 + 10H2O A. 13O2 + 10H2O B. 8CO2 + 10H2O C. 2C4H10 + 13O2 D.

arsen [322]

<u>Answer:</u> The products in the given chemical reaction are $8CO_2\text{ and }10H_2O$

<u>Explanation:</u>

Reactants are defined as the species which react in the reaction and are written on the left side of the reaction arrow.

Products are defined as the species which are produced in the reaction and are written on the right side of the reaction arrow.

For the given chemical equation:

$2C_4H_{10}+13O_2\rightarrow 8CO_2+10H_2O$

The reactants of the above reaction are $2C_4H_{10}\text{ and }13O_2$ and the products are $8CO_2\text{ and }10H_2O$

Hence, the products in the given chemical reaction are $8CO_2\text{ and }10H_2O$
