30.5 g of sodium metal reacts with chlorine gas to produce sodium chloride. How much (in grams) chlorine gas must react with thi

Lena [83]

Answer:

Mass of chlorine = 47.22 g

Explanation:

Given data:

Mass of sodium = 30.5 g

Mass of chlorine= ?

Solution:

Chemical equation:

2Na + Cl₂ → 2NaCl

Number of moles of Na:

Number of moles = mass/molar mass

Number of moles = 30.5g/ 23 g/mol

Number of moles = 1.33 mol

Now we will compare the moles of Cl ₂ with Na from balance chemical equation.

Na : Cl ₂

2 : 1

1.33 : 1/2×1.33 = 0.665 mol

Mass of chlorine gas:

Mass = number of moles × molar mass

Mass = 0.665 mol × 71 g/mol

Mass = 47.22 g

In the RGB color model, each color is represented by a numerical code that is written in parentheses and separated by commas.

<h3>What is the RGB model?</h3>

RGB is a color model with which it is possible to represent a color by mixing by adding the three primary colors of light.

A special feature of this model is that it is not a reference point for defining the color red, green, or blue because the same RGB values can display noticeably different colors on different devices.

To form a color, it must be taken into account that in the RGB model the incidence of each color (red, green or blue) is measured on a scale that goes from 0 to 255.

These values are represented in parentheses, separated by commas as shown in the image below:
