A) Anode - hydrogen gas
Cathode-oxygen gas
B) Hydrogen gas - The gas burns with a pop sound
Oxygen gas - The gas rekindles a glowing splint
C) The volume of gas produced at the cathode is 23
<h3>What is electrolysis?</h3>
Electrolysis is the process by which electric current is passed through a substance to effect a chemical change.
The electrolysis of water produces two volumes of hydrogen at the anode and one volume of oxygen at the cathode.
The hydrogen gas burns with a pop sound. It is easily identified by this test. Also, oxygen is known to rekindle a glowing splint and this is a commonly used test for oxygen gas.
Since the ratio of hydrogen produced at the anode to oxygen produced at the cathode is 2:1 by volume; then when 23 of oxygen is produced at the cathode, 46 of hydrogen is produced at the anode.

The “twins” is telophase then going up from there is interphase, prophase,metaphase, anaphase and then back to telophase (where I started at)
Answer:
The system and the surroundings together make up the universe. There are three types of systems in thermodynamics: open, closed, and isolated. An open system can exchange both energy and matter with its surroundings. ... A closed system, on the other hand, can exchange only energy with its surroundings, not matter.
98 °C + 273.15 = 371.15 K
The density (d) of the substance is the quotient obtained when we divide the mass (m) of an object by the volume (v) it occupies. Mathematically,
d = m / v
The density of soap is greater compared to that of the sponge because soap is so much heavier compared to sponge. Sponges are usually made up of porous lightweight materials.
