Explanation:

Number of protons + Number of neutrons = mass number

Number of neutrons = Mass number - Number of Protons

Does seeing a gas produced always mean a chemical reaction is occurring? Explain.

Answers

Seeing signs of a chemical reaction does not always mean that a reaction is happening. For example, a gas (water vapor) is given off when water boils. ... You can tell that it is a physical change because water vapor can condense to form liquid water. In a chemical change, a new substance must be produced.

Answer:

Seeing a gas produced not always means a chemical reaction is occurring.

Explanation:

The following clues for an occurrence of a chemical reaction:

Color: The color of the solution changes when mixed with another solution or on the addition of a solid to a solution.Temperature: Rise or fall in temperature of the substance formedPrecipitation: Formation of solid substance that is precipitateGas evolution: Bubbles or gas formation. Evolution of gas or fumes from the solution.Odor: The smell of the reacting mixture initially differs from the smell of the products

Yes, gas formation is one of the clues of the occurrence of a chemical reaction but it is not completely true.

This is because the evolution of gas also occurs when a substance undergoes a physical change.Water vapors on boiling water, sublimation of dry ice giving carbon dioxide gas.

So, from this, we can conclude that seeing a gas produced not always means a chemical reaction is occurring.

How does water vapor effect the way you breathe and how you can feel the climate change around you?

Answers

Fills your lungs with air that I’m not great

Answer:

Water vapour is an efficient greenhouse emission, because it will absorb radio wave radiation and radiates it back to the surface, so contributive to warming. when put next to alternative greenhouse gases, water vapour stays within the atmosphere for a way shorter amount of your time, However, When you exhale and it's cold outside, though, the vapour in your breath loses its energy quickly. instead of continued to maneuver freely, the molecules begin to pack themselves closely along. As they are doing this, they cut down and start to alter into either liquid or solid varieties of water.
