Answer:
b.Beta
Explanation:
mass number remains constant while atomic number has been increased by 1 unit . beta is electron like element where its mass number is 0 and atomic number is -1.
Answer: Heating the hydrated forms of cobalt chloride reverses the reactions above, returning cobalt chloride to the blue, water-free, or anhydrous, state. Water is "liberated" in these reactions, known as dehydration reactions.
Explanation:
The answer is (1) CaCl2. The reaction formula of this is HCl + Ca(OH)2 = CaCl2 + H2O. This is a reaction of base and acid. So the production is CaCl2 and H2O.
Cooking oil and the extinguishing agent combine to produce saponification, which creates a soapy foam blanket that separates fuel and oxygen.
<h3>What takes place when you add foam to a fire?</h3>
These are the ways foam functions: The foam smothers the flames by covering the fuel surface. The foam covering keeps the fuel surface and the flames/ignition source apart. Foam cools the fuel as well as any nearby metal surfaces.
<h3>What are some uses for a foam fire extinguisher?</h3>
The best and safest fire extinguisher to use on fires involving solid combustibles and flammable liquids (Class B) is foam (Class A). Typically, when liquids like gasoline, diesel, paint, oil, solvents, or spirits are burned, it can result in potentially deadly fires.
