Explanation

Oxidation half-reaction :

Zn - 2e = Zn^2+

Reduction half-reaction :

Cu^2+ +2e = Cu

Zn donates two electrons to form Zn^2+ ion and Cu^2+ gains two electrons to form Cu metal.

Thus, Cu^2+ is the oxidant.

Explanation

On a clear day at noon, the intensity of the solar energy reaching the Earth's surface is approximately 1kW/m 2 (kilowatts per square meter),

which is equivalent to 1000 W/m².

Among the given options, the closest match is:

1 kW/m² (or 1 K W m-2 if expressed in kilowatts per square meter).

Explanation

Dilatometry is a method of a physical nature.

It involves measuring the volume changes or dimensional changes of a substance or system as a function of temperature, pressure, or time.

This technique is commonly used in materials science, chemistry, and physics to study phase transitions, thermal expansion

Explanation

According to the latest classification, Bryophyta is divided into three classes:

• Hepaticopsida (Liverworts)
• Anthocerotopsida (Hornworts)
• Bryopsida (Mosses)

Hepaticopsida (Liverworts):

The name Hepaticopsida comes from the word “hepatic” meaning liver.

Liverworts come under this class.

Hepaticopsida is further divided into 4 orders:

1. Marchantiales (e.g. Riccia, Marchantia)
2. Sphaerocarpales (e.g. Sphaerocarpos)
3. Calobryales (e.g. Calobryum)
4. Jungermanniales (e.g. Pellia)
