$\mathbb\color{orange}{\tiny A\scriptsize N\small S\large W\Large E\huge R}$

surfactant, also called surface-active agent, substance such as a detergent that, when added to a liquid, reduces its surface tension, thereby increasing its spreading and wetting properties.
In the dyeing of textiles, surfactants help the dye penetrate the fabric evenly.
They are used to disperse aqueous suspensions of insoluble dyes and perfumes.

How many ions of aluminum oxide (Al²O³) are there in 200 g of Al²O³??

valentinak56 [21]

= 6.022 × 1020

Explanation;

Mole of aluminium oxide (Al2O3) is

⇒ 2 x 27 + 3 x 16

Mole of aluminium oxide = 102 g

i.e., 102 g of Al2O3= 6.022 x 1023 molecules of Al2O3

Then, 0.051 g of Al2O3 contains = 6.022 x 1023 / (102 x 0.051 molecules)

= 3.011 x 1020 molecules of Al2O3

The number of aluminium ions (Al3+) present in one molecule of aluminium oxide is 2.

Therefore, the number of aluminium ions (Al3+) present in 3.11 × 1020 molecules (0.051g) of aluminium oxide (Al2O3)

= 2 × 3.011 × 1020

= 6.022 × 1020

Consider a specific chemical reaction represented by the equation aA + bB → cC + dD. In this equation the letters A, B, C, and D

BartSMP [9]

Answer:

The answer to your question is: c = a + b - d

Explanation:

aA + bB → cC + dD

c could have any number from 1 to the number necessary in order that the

equation be balanced.

For example

c + d = a + b

c = a + b - d

If a = 1; b = 3 and d = 2

then c = 1 + 3 - 2

c = 2,

etc.
