Explanation

Electrons are lost in an oxidation reaction.

Oxidation simply means a gain of oxygen and an oxidizing agent is a substance that oxidizes something.

The reduction is the gain of electrons

Explanation

Acute diarrhea is defined as three or more loose or watery stools per day

The most common causes of acute and persistent diarrhea are:

• infections
• travelers' diarrhea
• and side effects of medicines.

**

Key measures to prevent diarrhea include:

• access to safe drinking water;
• use of improved sanitation;
• hand washing with soap

Explanation

Nitrogen is the chemical element with the symbol N and atomic number 7. It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772.

Symbol: N

Atomic number: 7

Boiling point: -195.8 °C

Explanation

1 radian ≈ 57.3 degrees, based on the formula: 

1 radian = 180/𝜋 degrees.

It is a standard angular measurement in mathematics and physics.

Explanation

When a car moves at constant velocity, it means there is no acceleration.

According to Newton’s First Law, if there’s no acceleration, the net force acting on the object is zero.

Explanation

F-block elements are also known as inner transition elements.

They include the lanthanides and actinides and are located at the bottom of the periodic table, separated into two rows.

This placement is due to their electron configuration, where the "n-2" f orbitals are being filled.

Explanation

The biosphere includes all of these: the Atmosphere, the Hydrosphere, and the Lithosphere.

The biosphere is the zone on Earth where life exists, encompassing the living organisms and their interactions with the surrounding environment, including the atmosphere, hydrosphere (water bodies), and lithosphere (land).

Explanation

Vacuum distillation is used to distill substances at lower temperatures by reducing the pressure, which lowers the boiling point of the substances.

Explanation

 Sweet peas are annual climbing plants with fragrant, butterfly-shaped flowers. 

They are part of the genus Lathyrus within the Fabaceae family. 

The name Lathyrus is derived from the Greek word for "pea," and odoratus means "scented". 

They are cultivated for their beautiful and fragrant flowers.

Explanation

• The sun generates electricity from a manner known as nuclear fusion. at some point of nuclear fusion, the high stress and temperature in the solar's middle cause nuclei to split from their electrons. Hydrogen nuclei fuse to shape one helium atom.
• sun power is electricity that comes from the solar. every day the solar radiates, or sends out, an vast amount of electricity. The sun radiates extra electricity in a single 2nd than human beings have used on the grounds that the start of time!
• It comes from in the sun itself. Like different stars, the solar is a huge gas ball made up by and large of hydrogen and helium. The solar generates energy in its middle in a system called nuclear fusion. at some point of nuclear fusion, the solar's extraordinarily high strain and extreme temperature reason hydrogen atoms to return apart and their nuclei (the principal cores of the atoms) to fuse or combine. 4 hydrogen nuclei fuse to become one helium atom. however the helium atom weighs less than the four nuclei that blended to shape it. some depend is lost at some point of nuclear fusion. The misplaced remember is emitted into area as radiant power.
