Supercritical mass results to an increase in the rate of fission. There is a chain reaction that will occur. Nuclear fission or explosion used in atomic bombs relies on supercritical mass. An atom splits into two, with each splitting into two pairs and so on, releasing energy in each step.
Both litmus paper and phenolphthalein are used as acid/base (pH) indicators.
Litmus paper:
Litmus paper will turn either blue or red when a drop of solution is added to the paper. Red indicates an acidic solution (pH is <4.5), and blue indicates a basic solution (pH >8.3).
Phenolphthalein:
Phenolphthalein is commonly used during acid/base titrations. When the solution is acidic and the indicator is added, it will remain colorless. If the solution is basic, the phenolphthalein will turn pink.
Answer:
Photosynthesis process
Explanation:
Photosynthesis removes carbon dioxide naturally — and trees are especially good at storing carbon removed from the atmosphere by photosynthesis.
Answer:
Sublimation
Explanation:
Deposition is the process in which a gas transforms into a solid without passing through the liquid phase.
In the opposite process, a solid transforms into a gas without passing through the liquid phase. This process is called sublimation.
Answer:
Important direct drivers include habitat change, climate change, invasive species, overexploitation, and pollution. Most of the direct drivers of degradation in ecosystems and biodiversity currently remain constant or are growing in intensity in most ecosystems
