Explanation

Ammonia has a pH level of around 11-12, which is strongly alkaline (basic).

Explanation

The equation A+B → AB represents an addition reaction, where two substances (A and B) combine to form a new compound (AB).

Explanation

• Carbon Dioxide (CO2) is a product of respiration.
• It not a factor that affects the process.

Explanation

The smooth endoplasmic reticulum (SER) is involved in the synthesis of lipids, including phospholipids and steroids.

Explanation

• Silicon is an example of a Semiconductor.
• Semiconductors like silicon have electrical conductivity between conductors and insulators.
• It enabling them to control electrical current flow in devices and integrated circuits.

Explanation

• The pressure exerted by a gas is a result of the countless collisions of gas molecules with the container walls, which transfer momentum.
• It force to the walls, causing pressure.
• This is a fundamental principle in kinetic molecular theory.

Explanation

The pH scale ranges from 1 to 14, with:

• 1-6 being acidic
• 7 being neutral (neither acidic nor basic)
• 8-14 being basic (alkaline)

Explanation

• Hydrogen and Oxygen combining to form water, which is an example of a synthesis reaction: 2H2 + O2 → 2H2O
• In this reaction, two substances (hydrogen and oxygen) combine to form a new compound (water).

Explanation

Our solar system takes approximately 250 million years to complete one orbit around the Milky Way galaxy.

Explanation

Dogs can hear sounds in the range of 67 Hz to 45,000 Hz, which is slightly higher than the human audible range.
