Which of the following materials could have been found in the giant cloud that formed the
Natalija [7]

Hydrogen and helium

These are the lightest atoms in the universe and are at the top-most of the periodic table.

Explanation:

These hydrogen and helium gas clouds when the collapse due to their own gravity, begin to fuses producing fusion energy that form stars. These light atoms become fused into heavier atoms in the center of these stars. When hydrogen and helium are fused, they form heavier atoms like those of carbon and oxygen. Supermassive stars, with intense gravity, will fuse even the heavier atoms like carbon into even heavier elements like Iron.

A gas is collected at 20.0 °C and 725.0 mm Hg. When the temperature is
krek1111 [17]

Answer:

676mmHg

Explanation:

Using the formula;

P1/T1 = P2/T2

Where;

P1 = initial pressure (mmHg)

P2 = final pressure (mmHg)

T1 = initial temperature (K)

T2 = final temperature (K)

According to the information provided in this question;

P1 = 725.0mmHg

P2 = ?

T1 = 20°C = 20 + 273 = 293K

T2 = 0°C = 0 + 273 = 273K

Using P1/T1 = P2/T2

725/293 = P2/273

Cross multiply

725 × 273 = 293 × P2

197925 = 293P2

P2 = 197925 ÷ 293

P2 = 676mmHg.

The resulting pressure is 676mmHg
