Name an acid which is highly corrosive and should never be tested by mouth.​

Answers

Answer:

We all know that HCI is highly corrosive mineral acid. It's produced naturally in our (Human being) Stomach

It (HCI) is produced by the gastric glands in stomach. HCI activates the enzyme Pepsin and creates an acidic medium which kills the bacteria which might have entered while digestion & also making it simpler for further digestion.

HCI does not harm our stomach because the gastric gland also produces Mucus which helps in preventing the damage of inner wall (layer) of stomach from the action of this Acid.

m = 240 grams

discuss one way in which global warming aggravates the effect of radiation​

Answers

The energy that then radiates out from the surface, longwave radiation, is trapped by the same greenhouse gases, warming the air, oceans, and land. This process, appropriately dubbed “the greenhouse effect,” is how global warming occurs.

One way by which global warming aggravates the effect of radiation is through greenhouse effect

The combined effects of global warming and radiation is explained as follows.

Global warming is the gradual increase in the temperature of the Earth's surface (land), ocean and the atmosphere through the heat from the radiation of the sun.

One way by which global warming aggravates the effect of radiation is through greenhouse effect.

This occurs when the radiation from the sun is allowed to pass into the Earth's atmosphere but subsequent heat radiating from the Earth is prevented from escaping into the space.

This greenhouse effect aggravates the effect of radiation.
