The new volume is 800 L.

From <em>Charles’ Law</em>, we know that

<em>V</em>₁/<em>T</em>₁ = <em>V</em>₂/T₂

Then

<em>V</em>₂ = <em>V</em>₁ × <em>T</em>₂/<em>T</em>₁

<em>V</em>₁ = 200 L; <em>T</em>₁ = 100 K

<em>V</em>₂ = ?;        <em>T</em>₂ = 400 K

∴ <em>V</em>₂ = 200 L × (400 K/100 K) = 800 L

<h2>Answer</h2>

The volume will be<u> 50 L</u>

<h2>Explanation</h2>

From Kelvin Law of Temperature, we know that

V_{1} T_{1} =V_{2} T_{2}

We know that

V_{1} = 200 L

T_1 = 100 K

T_2= 400 K

So,

V_{2} = V_{1} T_{1}/T_{2}

V_{2} = 200*100/400

V_{2} = 50 L

The answer of the givern question is 50L

At a pressure of 782.3 mm Hg and 34.4 °C, a certain gas has a volume of 362.4 mL. What will
german

Answer: v2=331.289mL

Explanation:

Formula for ideal gas law is p1v1/T1=p2v2/T2

P1=782.3mmHg

P2=769mmHg at STP

V1=362.4mL

V2=?

T1=273+34.4=307.4k

T2=273k at STP

Then apply the formula and make v2 the subject of formula

V2= 782.3×362.4×273/760×307.4

V2=77397006.96/233624

V2=331.289mL

How does the density of protostars compare to other stars?
lorasvet [3.4K]

Protostars are less dense than other stars.  

Explanation:

Protostars are very young ‘stars’ made from hydrogen clouds that are beginning to coalesce and collapse under their weight. The hydrogen has not even begun fusing. Therefore, they are mainly made of hydrogen which is the lightest element in the universe.

Stars, however, have begun fusing hydrogen to other heavier elements like helium, carbon, oxygen, and iron. The elements are much heavier than hydrogen making other stars much denser than protostars.

Which of the following pairs consists of a weak acid and a strong base? (1 point)
notka56 [123]

Answer:

acetic acid, sodium hydroxide

Explanation:

A strong acid is an acid that ionizes in water to give all its hydrogen ion. Weak acid only ionize to a certain degree. Acetic acid (CH3COOH) only ionize to give one hydrogen ion despite having other hydrogen atom. This account for its weak nature as an acid as shown below:

CH3COOH <=> H^+ + CH3COO^-

A strong base is a base that ionizes in water to give all it hydroxide ion. Sodium hydroxide(NaOH) ionizes to give all its hydroxide ions. This make it a strong base as shown below;

NaOH <=> Na^+ + OH^-
