Magicians often use ‘flash powder’ in their acts. Flash powder contains 69.0% potassium chlorate (31.9% K, 28.9% Cl, 39.2% O) and the remainder is aluminium. Calculate the percentage composition by mass of each element in flash powder

Answers

Answer:

[tex]\rm K[/tex]: approximately [tex]22.0\%[/tex].

[tex]\rm Cl[/tex]: approximately [tex]19.9\%[/tex].

[tex]\rm O[/tex]: approximately [tex]27.0\%[/tex].

[tex]\rm Al[/tex]: [tex]31.0\%[/tex].

Explanation:

Consider a [tex]100\; \rm g[/tex] sample. There would be [tex]69.0\% \times 100\; \rm g = 69.0\; \rm g[/tex] of [tex]\rm KClO_{3}[/tex] and [tex]100.0\; \rm g - 69.0\; \rm g = 31.0\; \rm g[/tex] of [tex]\rm Al[/tex].

Out of that [tex]69.0\; \rm g[/tex] of [tex]\rm KClO_{3}[/tex]:

[tex]31.9\%[/tex] (by mass) would be [tex]\rm K[/tex]: [tex]31.9\% \times 69.0\; \rm g \approx 22.0\; \rm g[/tex].

[tex]28.9\%[/tex] (by mass) would be [tex]\rm Cl[/tex]: [tex]28.9\% \times 69.0\; \rm g \approx 19.9\; \rm g[/tex].

[tex]39.2\%[/tex] (by mass) would be [tex]\rm O[/tex]: [tex]39.2\% \times 69.0\; \rm g \approx 27.0\; \rm g[/tex].

Overall, the composition (by mass) of each element in this mixture would be:

[tex]\rm K[/tex]:

[tex]\begin{aligned} & \frac{31.9\% \times 69.0\; \rm g}{100\; \rm g} \\ =\; & 31.9\% \times 69.0\% \\ \approx \; & 22.0\%\end{aligned}[/tex].

[tex]\rm Cl[/tex]:

[tex]\begin{aligned} & \frac{28.9\% \times 69.0\; \rm g}{100\; \rm g} \\ =\; & 28.9\% \times 69.0\% \\ \approx \; & 19.9\%\end{aligned}[/tex].

[tex]\rm O[/tex]:

[tex]\begin{aligned} & \frac{39.2\% \times 69.0\; \rm g}{100\; \rm g} \\ =\; & 39.2\% \times 69.0\% \\ \approx \; & 27.0\%\end{aligned}[/tex].

[tex]\rm Al[/tex]:

[tex]\begin{aligned}& \frac{100\; \rm g - 69.0\; \rm g}{100\; \rm g} \\ =\; & 100\% - 69.0\% \\ =\; & 31.0\%\end{aligned}[/tex].

divide rs 120 I three parts which are in THE ratio of 1:2:3.​

Answers

Answer:

20,40,60

Explanation:

Let the three parts be 1x, 2x and 3x

The the sum of three parts will be 1x+2x+3x = 120

6x=120

x=120/6

x=20

1x= 20x1=20

2x= 20x2=40

3x= 20x3=60

So 120 is divided in three parts that is 20,40,60

Answers

The levels of carbon dioxide in the atmosphere are estimated to be higher than at any time in the past 420,000 years. That is option B

Carbon dioxide is a very harmful compound which is easily released into the atmosphere through burning of fossil fuels and other carbon compounds in plenty of air.

The released carbon dioxide rises to the upper atmosphere and blocks the radiation of solar energy back into the space. This precipitates a global temperature increase called the greenhouse effect.

According to Intergovernmental Panel on Climate Change (IPCC) in a current research discovered that CO2 concentration in the earth’s atmosphere is higher than at any point during the last 650,000 years. They where able to study this through the study of higher levels of CO2 concentration which coincide with higher temperatures.

Therefore the correct option is B which states that the levels of carbon dioxde in the atmosphere are estimated to be higher than at any time in the past 420,000 years.

O B. Convert the 10 g of NaCl to moles of NaCl.


C. Convert the 2 kg of water to moles of water.


O D. Convert the 10 g of NaCl to kg of NaCl.

Answers

Answer:

O B. Convert the 10 g of NaCl to moles of NaCl.

Explanation:

The formula for finding the molality is m=moles of solute/kg of solvent. The solute for this question is NaCl and the solvent is water.

(10g NaCl)(1 mol NaCl/58.44g NaCl)=0.1711 mol NaCl

58.44 is the molar mass of NaCl

m=0.1711 mol NaCl/2 kg H2O

m=0.085557837

Answers

The correct answer is: It contains both an amino functional group and a carboxyl functional group. In a solution, the amino group can

decrease acidity, while the carboxyl group can increase acidity.

The carboxyl functional group is acidic while the amine group is basic.

In an amino acid, there are two functional groups;

The amine groupThe carboxyl group

The carboxyl functional group is acidic because it contains a replaceable or  ionizable hydrogen ion. The amine group on the other hand is capable of accepting a proton hence it is basic.

Therefore, In a solution, the amine group can  decrease acidity, while the carboxyl group can increase acidity.

URGENT PLEASE ELPP!!!Calculate the density of a piece of metal that has a mass of 2.5 × 102 kg and a volume of 4.1 × 103 m3.

Answers

Answer:

Density =mass/Volume

First of all let's find the mass

= 2.5 ×102kg

= 225kg

Then the volume

=4.1 × 103 m3

=422.3m3

225kg /422.3m3

=0.53279659

The density of a piece of metal that has a mass of 2.5 × 102 kg and a volume of 4.1 × 103 m3  will be 6.03  kg/m³ .

What do you mean by  the density of a substance ?

Density is defined as the ratio of mass of the object to the volume of the object. Different substances have different densities.

The mathematical expression for density is as follows:

Density=Mass/Volume

The mass of a substance is expressed in kilograms and the volume is expressed in liter.

Thus, the unit of density is kg L⁻¹.

The density of a substance does not depend on the amount of the matter.

Thus, density is an intensive property.

To calculate  the density -:

Given,

Mass= 2.5 ×102 kg=2550 kg

Volume=4.1 × 103 m³=422.3m³

Density=mass/volume

Density=2550/422.3

Density=6.03kg/m³

Hence, 6.03kg/m³ is the  density of a piece of metal .
