Experiment results are as colorful as rainbows are. Have you check?

# data[].attributes.body
During this experiment, we followed the steps carefully yet the results have a slight discrepancy on the mass. We concluded maybe the humidity and temperature during that time contributed to the error. That's an experiment and sometimes it doesn't goes well with what you expected. Nonetheless, you can try again.

Can we separate the 2 elements that composes the water?

# data[].attributes.body
Yes, through this experiment of electrolysis we can separate the 2 elements when electric current flows. The cloudy side with less volume contains the Hydrogen and the other were bubbles are visible has the Oxygen.

Interdiffusion of Gases

A classic demonstration of interdiffusion involves ammonia (NH₃) and hydrogen chloride (HCl) gases. When brought together in a closed tube, they react to form ammonium chloride (NH₄Cl), which forms a white smoke. The position of the smoke ring indicates the relative diffusion rates of the two gases.

The concept about interdiffusion of gases can be applied in environmental science explaining how pollutants disperse in the air.

Titration of a Strong Acid with a Strong Base

Titration is a quantitative analytical technique used to determine the concentration of a solution.

Titrations are essential in various fields, including:

Determining concentrations of acids and bases.

Analyzing water quality.

Quality control of drug formulation

Essentially, this law tells us that the total mass of all the substances involved in a chemical reaction remains constant. The mass of the reactants (starting materials) must equal the mass of the products (end materials).

When an acid reacts with a carbonate, it produces carbon dioxide gas, water, and a salt.

Cathode (negative electrode): Hydrogen gas is produced at the cathode.

Anode (positive electrode): Oxygen gas is produced at the anode.

The volume of hydrogen gas produced is twice that of oxygen gas due to the ratio of hydrogen and oxygen atoms in water.

Electrolysis is a clean method of producing hydrogen, a potential clean energy source.

This movement transfers heat from one part of the fluid to another.

Such as the rising bubbles of hot water are convection currents; the movement of air masses due to temperature differences creates weather patterns; warm ocean water moves towards colder regions, influencing climate and

convection currents in the Earth's mantle are responsible for plate tectonics.

# data[].attributes.body
Convection currents are the circular motion of a fluid (liquid or gas) caused by differences in temperature. This movement transfers heat from one part of the fluid to another.
