Answer:

The volume inside the balloon is = 121 m^{3}

Explanation:

Temperature T = - 1 °c = 272 K

Pressure = 0.7 atm = 71 k pa

No. of moles = 3.8

Mass of the gas inside the volume = 3.8 × 4 = 15.2 kg

From ideal gas equation

P V = m R T

Put all the values in above formula we get

71 × V =15.2 × 2.077 × 272

V = 121 m^{3}

Therefore the volume inside the balloon is = 121 m^{3}

Answer:

\large \boxed{\text{121 L}}

Explanation:

We can use the Ideal Gas Law.

pV = nRT

Data:

p = 0.700 atm

n = 3.80 mol

T = -1  °C

Calculations:

1. Convert the temperature to kelvins

T = (-1 + 273.15) K= 272.15 K

2. Calculate the volume

\begin{array}{rcl}pV &=& nRT\\\text{0.700 atm} \times V & = & \text{3.80 mol} \times \text{0.082 06 L}\cdot\text{atm}\cdot\text{K}^{-1}\text{mol}^{-1} \times \text{272.15 K}\\0.700V & = & \text{84.86 L}\\V & = & \textbf{121 L} \\\end{array}\\\text{The volume of the balloon is $\large \boxed{\textbf{121 L}}$}

Rank the following elements by electron affinity, from most positive to most negative EA value. Rank from most positive to most
Svetlanka [38]

Answer:

Most positive = rubidium

Most negative = fluorine

Explanation:

Electron affinity of an element is the energy released when an electron is attached to a neural atom to form an ion in its gaseous state.

X + e⁻ → X⁻

Electron affinity is similar to electronegativity which is the tendency at which an atom accepts an ion towards itself.

Electron affinity increases across the period and decreases down the group in the periodic table.

In the above option,

Fluorine has the highest electron affinity

Rubidium has the lowest electron affinity

Tellurium and then finally Phosphorus

Helium in this case would have the lowest electron affinity because it has filled orbital and does not require any electron to attain stability. Technically, Helium has the lowest or is expected to have the lowest electron affinity which is close to zero according to quantum mechanics.

Most positive = rubidium

Most negative = fluorine.

You can check periodic table for their exact values

1 What direction do<br> molecules move in?
notsponge [240]

Answer:

The majority of the molecules move from higher to lower concentration, although there will be some that move from low to high. The overall (or net) movement is thus from high to low concentration.

How do cells use lipids and carbohydrates?
Nata [24]

Answer:

Animals tend to use carbohydrates primarily for short-term energy storage, while lipids are used more for long-term energy storage. Carbohydrates are stored as glycogen in animals while lipids are stored as fats (in plants carbohydrates are stored as cellulose and lipids as oils)
