Answer:
• An acid is an electrolyte that hydrolyses in water to release hydrogen ions.
• pH level of an acid;
- Strong acid → 0 - 3.8
- Weak Acid → 4.0 - 6.7
They use anaerobic cellular respiration to produce NAD+ from NADH.
Auroras occur in the <u>"thermosphere".</u>
The thermosphere lies between the exosphere and the mesosphere.It is a district of expanding temperature in Earth's climate that is situated over the mesosphere.
The thermosphere significantly helps in ensuring the earth and making space investigation and present day types of correspondence conceivable. It additionally supports and ensures life on the planet. It reuses water, retains the sun's energy, and makes a moderate temperature.
The aurora (Northern Lights and Southern Lights) generally present in the thermosphere. It is a natural electrical marvel described by the presence of streamers of rosy or greenish light in the sky, particularly close to the northern or southern attractive shaft. The impact is caused by the communication of charged particles from the sun with iotas in the upper atmosphere.
4) Carbon Dioxide (CO2)
This gaseous evolution or precipitation of CO2 gas during yeast fermentation, causes the bread to "rise" as the CO2 gas is formed, since gas is less dense than solids and liquids.
