Oxygen difluoride is a hazardous, highly explosive gas used as a propellant. A sample of this compound weighing 0.432 grams is analyzed. It contains .128 grams of oxygen. What is the percentage composition of oxygen and fluorine in this compound ? (Show work)

Answers

Answer 1

Answer:

Percentage composition of oxygen = 29.69%

Percentage composition of fluorine = 70.37

Explanation:

Given:

Mass of compound = 0.432 grams

Mass of oxygen = 0.128 grams

Find:

Percentage composition of oxygen

Percentage composition of fluorine

Computation:

Percentage composition of oxygen = [0.128/0.432]100

Percentage composition of oxygen = 29.69%

Percentage composition of fluorine = [(0.432 - 0.128)/0.432]100

Percentage composition of fluorine = 70.37

The reason of why rainforest plants adapted to be a different shape  as compared to the desert plants is because of option d. as the rainforest environment is different than the desert environment.

Adaption of the rainforest plants to the different shapes and size?

It can be like:

Drip tips - where plants contains leaves with pointy tips.Buttress roots - These contain large roots that have ridges that develop a large surface area. Epiphytes - It lives on the branches of trees high up in the canopy.

hence,  The reason of why rainforest plants adapted to be a different shape as compared to the desert plants is because of option d. as the rainforest environment is different than the desert environment.

A resistance of 60Ω has a current of 0.73A through it when it is connected to the terminals of a battery. The voltage of the battery is ______V. (Just write the number.

Answers

Answer: 43.8 Volts

Explanation:

Ohms law states that current is directly proportional to voltage applied.

[tex]V=I\times R[/tex]

where V = voltage = ?

I = current = 0.73 A

R = resistance = 60 ohm

Putting in the values we get:

[tex]V=0.73A\times 60ohm=43.8V[/tex]

Thus the voltage of the battery is 43.8 Volts

3- a) write the formula unit of calcium fluoride.

b) A certain mass m of calcium fluoride contains 1.2*10^23 anions. Deduce the mass (m). NA= 6.02*10^23

Answers

Answer:

a) CaF₂.

b) 7.81g of CaF₂ are present.

Explanation:

a) The calcium ion has as charge Ca²⁺ and fluoride ion is F⁻, that means formula unit is:

CaF₂

b) 1 molecule of CaF₂ contains 2 anions, F⁻. Thus, the moles of CaF₂ is:

1.2x10²³ anions * (1 moleculeCaF₂ / 2 anions) = 6x10²² molecules of CaF₂

6.022x10²³ molecules = 1mol:

6x10²² molecules of CaF₂ * (1mol / 6.022x10²³molecules) = 0.10 moles CaF₂.

1 mole of CaF₂ has a mass of 78.07g:

0.10 moles CaF₂ * (78.07g / mol) =

7.81g of CaF₂ are present

Which ionic compound would you predict to have a higher boiling point: NaBr or
Na2S
Why did you select this compound?

Answers

Answer:

The boiling point of NaBr is higher than that of Na2S

Explanation:

Bromine has higher electronegativity as compared to the sulphur. The ionic strength of the bond formed with Sodium is higher in the NaBr compound. The higher the ionic bond strength the higher will be the boiling point

Also the size of bromine is large as compared to that of sulphur. Large molecules consists of more electron and hence they create der Waals attractive forces due to which the boiling point of compound increases.

Hence, the boiling point of NaBr is higher than that of Na2S

A recipe for bread states that the dough must bake for 40 minutes at a temperature of 190°C. The oven you are using has temperature marking on the dial that are in units of degrees Fahrenheit. At what Fahrenheit temperature must the bread be baked? What would this temperature be in Kelvins?

Answers

Answer:

374°F

463.15K

Explanation:

This particular Question wants to test knowledge on the conversion of the units of temperature from celsius degree to degree Fahrenheit. Also, the conversion of degree celsius to kelvin.

The value given which is 190 degree celsius can be converted into degree Fahrenheit using the formula below;

(x°C × 9/5 ) + 32.

Therefore, x = 190°C =( 190°°C × 9/5) + 32 = 374°F.

The conversion of degree celsius to kelvin is given below as;

x°C + 273.15 .

Therefore, x = 190°C = 190°C + 273.15 = 463.15K.

Therefore, the temperature needed to bake at Fahrenheit and kelvin are 374°F and 463.15K respectively.

A gas at a pressure of 360 torrs and a volume of 750 ml. If the pressure becomes 1.5 atm what is the new volume?

Answers

Answer:

V₂ = 236.84 mL

Explanation:

The relation between pressure and volume is inverse.

We can write it as follows :

[tex]P_1V_1=P_2V_2[/tex]

We have,

P₁ = 360 torrs, V₁ = 750 mL, P₂ = 1.5 atm = 1140 torr.

So,

[tex]V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{360\times 750}{1140}\\\\V_2=236.84\ mL[/tex]

So, the new volume of the gas is 236.84 mL.
