The products of electrolysis can be predicted for a given electrolyte. Sample exam questions - chemical changes - AQA Understanding how to approach exam questions helps to boost exam performance.

The speed of a chemical reaction is affected by temperature, concentration, particle size and the presence of a catalyst. It can be calculated by measuring changes in reactants/products.

Scientists have achieved the first real-time visualization of how excited-state aromaticity emerges within just hundreds of ...

Iron oxide, aluminum, and a catalyst are placed in a flowerpot. The reaction is extremely exothermic resulting in molten iron and aluminum dripping into sand below the flowerpot. The demonstration ...

Students help design experiments to test whether the temperature of water affects the rate of evaporation and whether the temperature of water vapor affects the rate of condensation. Students also ...

Both chemical changes generating electric currents and chemical reactions triggered by the passage of electricity can be considered electrochemical reactions. Thermal stability in high-nickel ...

The Biden-era rules require thousands of hazardous-chemical sites to adopt new safeguards against storms, spills and other ...

AUGUSTA, Ga. (WRDW/WAGT) - A last-minute effort is underway to convince Georgia’s Environmental Protection Division that modifications to the Solvay chemical plant’s permit will worsen the air ...
