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?
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.

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?
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.

what is the other term used to describe tropical cyclone when it is formed in the northwestern part of the pacific ocean
Answer:
Typhoons
Explanation:
A tropical cyclone is a word that is used by meteorologists to explain a rotating, organized system of clouds & thunderstorms that take their origins over tropical or subtropical waters and also possess closed but low-level circulation.
Now, In the Northwest part of the Pacific ocean, these tropical cyclones which are west of the dateline are referred to as Typhoons while In the southwest Pacific and in the Indian Ocean they are called Cyclones. Lastly, those that form over the Atlantic Ocean or eastern Pacific Ocean are referred to as hurricanes

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.

What do you think is hotter, a blue flame or a red flame, explain why?
Answer:
Blue Flame
Explanation:
Because, flames consists of photons which can be defined as quantum of energies of varying freq. and wavelengths in the electromagnetic spectrum, blue has higher freq than the red colour. Thus, energy is directly proportional to energy which makes the blue flame hotter than the red flame.
¿Cuántos moles de bióxido de Nitrógeno (NO 2) se forman cuando reaccionan 5 moles de Nitrógeno (N 2)?
Answer:
10 moles de NO2
Explanation:
Tenemos la ecuación de la reacción como sigue;
N2 (g) + 2 O2 (g) → 2 NO2 (g)
Asi que;
Si 1 mol de nitrógeno produce 2 moles de NO2
5 moles de nitrógeno producirán 5 * 2/1 = 10
Por tanto, se producen 10 moles de NO2 moles

3. How many atoms are in 85 moles H2O?
Answer:
5.119 *10^25
Explanation:
1 mole = 6.022 * 10^23
[tex]\frac{85 mol H20}{1} =\frac{6.022*10^2^3}{1 mol H20}[/tex]
the moles cancel out so you get
85 * (6.022*10^23)
Plug that into the calculator so you get:
5.119 *10^25

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
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?
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
