Answer:
the overall cell potential
Explanation:
We must bear in mind that the standard hydrogen electrode is a reference electrode whose electrode potential has been arbitrarily set at 0 V.
The standard hydrogen electrode consists of hydrogen ion solution and hydrogen gas together with a platinum electrode.
The overall cell potential is the reduction potential of the substance being determined using the standard hydrogen electrode as a reference electrode since its electrode potential is set at zero volts.
Answer:D
Explanation:
I’ve had this question before. Since it’s stairs, the potential energy would decrease due to height decrease and it will be transformed to kinetic energy
The precaution to be taken while measuring the temperature of a liquid in a beaker is applying proper heat balance and taking all the required precautions.
- A beaker with an open top contains a sample of liquid. It exposes this sample to light.
- That liquid absorbs the light energy, turning it into heat energy. As a result, the liquid becomes warmer and evaporation is accelerated. As a result, there is less liquid in the beaker.
- Since it is well known that the surface temperature of a liquid, along with air movement above the liquid surface, is one of the dominant factors affecting evaporation, I want to measure the evaporation rate as a function of surface temperature.
- This can be done by applying a heat balance.

Answer:
it would need to lose energy
Explanation:
I don't really have an explanation
The outer shell of the atoms in group D of the periodic table consists of elements whose outermost shell is full
Their outermost shell consist of elements with valence electrons
The group D elements are found in between S and P blocks of the periodic table
<h3>What is an element?</h3>
An element is a substance which cannot be split into simpler units by ordinary process.
Few examples of elements which belongs to group D include the following:
- Scandium
- Titanium
- Vanadium
- Chromium
- Manganese
- Iron
- Nickel
- Copper
- Zinc
